Grafting, seed production and the DREVO gene pool

Grafting, seed production and the DREVO gene pool

System for the preservation, reproduction and development of plant heritage

Grafting, seed production, and genetic conservation are three interrelated areas that ensure the sustainable development of DREVO's forest gardens, nurseries, and restoration projects.

Their common goal is not just to produce planting material, but to preserve biological diversity, local varieties, stable genetic lines, and plant properties accumulated over generations.

The main principle of DREVO:

We preserve not only individual plants, but also their origins, hereditary qualities, ability to adapt and pass on life to future generations.

1. Three directions of a unified system

Vaccination

Allows the propagation of specific varieties and the combination of the properties of the rootstock and scion.

Seed production

Ensures the receipt of seeds of known origin, quality and purpose.

Genetic fund

Preserves varieties, natural populations, ecotypes, mother plants, seeds, tissues and pedigrees.

These directions complement each other.

Grafting preserves the variety virtually unchanged.

Seed propagation creates genetic diversity.

The genetic fund ensures long-term preservation and control of origin.

2. Basic methods of plant propagation

Reproduction can be by seed or vegetatively.

Seed propagation

A new plant develops from a seed.

Advantages:

a new genetic combination is formed;

population diversity increases;

plants can better adapt to local conditions;

usually a full-fledged root system is formed;

you can get a large amount of planting material.

Limitations:

the offspring does not always repeat the properties of the parent variety;

fruiting may begin later;

fruit quality may vary;

some of the hereditary traits are split.

Vegetative propagation

A new plant is obtained from a part of the mother plant.

Main methods:

vaccination;

cuttings;

deductions;

root shoots;

dividing the bush;

tissue culture.

Such a plant is genetically close to the parent specimen if no mutations or other changes occur during the reproduction process.

3. The importance of genetic diversity

A genetically uniform planting may be productive, but it remains vulnerable.

If thousands of trees have nearly identical properties, a single disease or climate event can damage a significant portion of the stand.

Genetic diversity increases the likelihood that individual plants will be resistant to:

drought;

frost;

heat;

salinization;

new pests;

diseases;

change of flowering season;

unstable precipitation.

Therefore DREVO combines:

varietal grafted trees;

local seedlings;

natural populations;

experimental hybrids;

old traditional varieties;

reserve genetic lines.

4. What is vaccination?

Grafting is the joining of parts of two plants in such a way that they grow together and continue to develop as a single organism.

The lower part is calledrootstock.

The upper varietal part is calledgraft.

The rootstock forms:

root system;

part of the trunk;

plant resistance to soil;

growth force;

part of the adaptive properties.

The scion forms:

varietal crown;

flowers;

fruit;

most of the economically significant characteristics of the variety.

5. Why is vaccination used?

Vaccination allows:

preserve a valuable variety;

accelerate the onset of fruiting;

control the size of the tree;

adapt the variety to the soil;

increase resistance to certain diseases;

restore damaged trees;

change the variety of an adult tree;

grow several varieties on one plant;

preserve rare genetic lines.

6. Rootstock

The rootstock is the foundation of the grafted plant.

When choosing it, the following are evaluated:

compatibility with scion;

growth force;

winter hardiness;

heat resistance;

drought resistance;

salinity tolerance;

soil requirements;

disease resistance;

root depth;

tendency to root suckers;

durability;

influence on the onset of fruiting.

The rootstock can be:

seed;

clonal;

local;

hybrid;

dwarf;

semi-dwarf;

vigorous.

7. Seed rootstock

Seed rootstock is grown from seed.

Its advantages:

developed root system;

possible durability;

resistance to adverse conditions;

genetic diversity.

Flaws:

uneven growth force;

different compatibility;

unpredictable reaction to soil;

late fruiting of some grafted plants.

Seed rootstocks are especially important for:

nature-like gardens;

long-lived trees;

dry areas;

restoration of local populations;

selection work.

8. Clonal rootstock

Clonal rootstocks are propagated vegetatively.

Advantages:

homogeneity;

predictable size;

earlier fruiting;

convenience for industrial gardens;

possibility of tight fit.

Limitations:

less genetic variability;

sometimes weaker root system;

possible need for support;

increased dependence on care;

the same vulnerability of the entire planting.

In DREVO projects, it is advisable to combine clonal rootstocks with seed and local forms.

9. Scion

The scion is taken from a proven mother plant.

The following are selected for preparation:

healthy one-year-old shoots;

well-ripened wood;

prominent kidneys;

branches without signs of disease;

typical parts of the crown.

For each scion the following is recorded:

mother tree;

variety;

date of procurement;

place of preparation;

responsible person;

storage conditions;

vaccination results.

10. Compatibility of rootstock and scion

For successful grafting, plants must have sufficient botanical and physiological compatibility.

The most reliable vaccinations are:

within one variety;

between varieties of the same species;

between closely related species of the same genus.

The more distant the relationship, the higher the probability of incompatibility.

It can manifest itself:

straightaway;

in a few months;

in a few years;

after the start of intensive fruiting.

Signs of incompatibility:

poor fusion;

thickening at the grafting site;

cracking;

premature yellowing;

poor growth;

scion breakage;

sudden death of a tree.

11. Basic methods of grafting

Copulation

It is used when the rootstock and scion have similar thickness.

Improved copulation

Uses additional longitudinal cuts - tongues, which increase the stability of the connection.

Cleft grafting

Suitable for grafting thicker branches or young trees.

Bark grafting

It is used during active sap flow, when the bark separates well.

Grafting

Instead of a cutting, one bud with a small piece of tissue is transferred.

Inoculation by rapprochement

The two plants first grow on their own roots and are joined without completely separating the scion.

Bridge grafting

It is used to restore the movement of substances through a damaged section of the trunk.

12. Conditions for successful grafting

It is necessary to ensure:

clean and sharp tools;

precise cut;

combination of cambial layers;

protection from drying out;

strong fixation;

suitable temperature;

the right time;

infection control;

subsequent removal of rootstock shoots.

It is important not only to join the wood, but to ensure contact of living tissues capable of forming a connecting callus.

13. Timing of vaccinations

The period depends on:

the type;

climate;

method of grafting;

rootstock conditions;

storage conditions of the scion.

Main periods:

winter table grafting;

early spring grafting;

grafting during sap flow;

summer budding;

autumn grafting in protected conditions.

All deadlines must be specified for a specific region and type.

14. Post-vaccination care

After the operation it is necessary:

check the fixation;

protect the area from drying out;

remove shoots below the graft;

control the growth of the scion;

loosen or remove the harness;

tie up a young shoot;

protect from wind and animals;

record the result.

During the first season, it is important not to allow the young scion to become overloaded with fruits.

15. Re-grafting an adult tree

Re-grafting allows you to replace a variety without removing the entire root system.

It is applied if:

the variety is not suitable;

the harvest is of low quality;

a pollinator needs to be added;

it is necessary to preserve the old trunk;

The tree has a valuable root system.

It is better to re-graft a large tree in stages, preserving part of the original crown until the new scions have strengthened.

16. Tree-garden

Several compatible varieties can be grown on one tree.

Such a tree can:

ensure cross-pollination;

produce crops at different times;

preserve rare varieties;

be used for educational purposes.

However, it is necessary to take into account:

different growth strength of branches;

different yields;

flowering time;

compatibility;

uniformity of illumination;

risk of displacement of weak varieties.

17. Mother garden

A mother garden is created to obtain:

grafting material;

cuttings;

seeds;

otvodkov;

root suckers.

Mother plants should have:

confirmed origin;

typical characteristics of the variety;

good health;

sustainable productivity;

absence of dangerous infections;

digital passport.

A mother garden shouldn't be viewed solely as a source of harvest. Its primary value is the high-quality, traceable propagation material.

18. Seed production

Seed production is a system of obtaining, testing, storing and distributing seeds with known characteristics.

It includes:

Selection of parent plants.

Control of flowering and pollination.

Seed collection.

Cleaning.

Drying.

Quality control.

Storage.

Germination.

Documentation of offspring.

Field evaluation of the new generation.

19. DREVO Seed Categories

Natural seeds

Collected from natural plant communities.

Seeds of local populations

They originate from plants that have been adapted to a specific area for a long time.

Varietal seeds

Obtained from registered or sustainably reproduced varieties.

Open pollinated seeds

The mother plant is known, but the origin of the pollen may be mixed.

Controlled pollination seeds

Both parents are known.

Selection seeds

Obtained through directional selection or crossing.

Reserve seeds

They are stored for long periods and are not used for regular production.

20. Mother and father plant

In seed propagation, the offspring receives hereditary material from both parents.

The mother plant forms:

ovule;

tissues of seed and fruit;

conditions for embryo development.

The paternal plant transmits hereditary material through pollen.

In open pollination, the mother plant is known, but the father plant may be unknown or only approximately determined.

21. Pollination control

To obtain seeds of known origin, the following are used:

spatial isolation;

temporary isolation;

protective bags;

removal of unwanted flowers;

hand pollination;

branch marking;

Pollinator control;

genetic testing of offspring.

Controlled pollination is especially important for breeding and preserving rare lines.

22. Open pollination

Open pollination is beneficial for:

maintaining wide genetic variability;

population adaptation;

nature-like seed production;

creation of new sustainable forms.

To do this, you need to have a sufficiently large number of unrelated mother plants.

A collection of seeds from a single tree does not represent the full diversity of the entire population.

23. Selection of mother plants

The mother plant is assessed based on several years of observation.

The following are taken into account:

health;

height;

form;

productivity;

fruit quality;

weather resistance;

absence of obvious defects;

pest resistance;

conformity to grade;

ecological value.

You can't choose your parents based on just one successful season.

24. Seed collection

Seeds are collected:

at an optimal stage of maturity;

in dry weather, whenever possible;

separately from each mother plant;

with mandatory marking;

without mixing unknown batches.

The following are recorded:

date;

place;

coordinates;

view;

mother plant number;

condition of fruits;

collection method;

intended purpose.

25. Cleaning seeds

Cleaning may include:

separation from pulp;

removal of shells;

washing;

screening;

sorting;

separation of empty and damaged seeds;

disinfection using acceptable methods.

The method depends on the biology of the species.

26. Drying

Seeds cannot be dried using a single universal method.

Some species tolerate deep drying and long-term storage well.

Others quickly lose their germination capacity when dried out.

Therefore, the DREVO catalogue indicates for each type:

permissible humidity;

drying speed;

temperature;

sensitivity to drying out;

maximum shelf life.

27. Types of seeds by storage ability

Orthodox seeds

They tolerate low humidity and storage at low temperatures.

Recalcitrant seeds

Sensitive to drying and freezing.

They need to:

sow quickly;

store for a short period of time;

preserve the plant using other methods.

Intermediate seeds

They have limited tolerance to drying and cold.

The storage type must be determined for each species separately.

28. Seed dormancy

A mature seed does not always germinate immediately.

The reasons for rest may be:

hard shell;

immaturity of the embryo;

chemical inhibitors;

physiological rest;

the need for a seasonal temperature cycle.

To overcome peace the following are used:

stratification;

scarification;

soak;

washing;

temperature alternation;

exposure to light;

natural winter sowing.

29. Stratification

Stratification is keeping seeds in a moist environment at a certain temperature.

It can be:

cold;

warm;

combined;

multi-stage.

The party passport records:

start date;

temperature;

humidity;

substrate;

duration;

results.

30. Scarification

Scarification breaks the seed's hard shell.

Methods:

mechanical;

thermal;

water;

chemical;

natural.

The treatment should not damage the embryo.

31. Checking the quality of seeds

Key indicators:

party purity;

humidity;

weight;

fullness;

germination energy;

laboratory germination;

field germination;

health;

authenticity;

genetic purity.

Laboratory germination does not guarantee the same survival rate in the field.

32. Germination test

A representative sample is selected for the party.

The following are recorded:

number of seeds;

germination conditions;

start of the test;

duration;

number of normal sprouts;

number of weak seedlings;

number of dead seeds.

The results are indicated along with the testing date.

33. Field germination

Field germination depends on:

temperatures;

humidity;

soil structure;

sowing depth;

pests;

fungal diseases;

quality of site preparation.

Therefore, laboratory and field results are stored separately.

34. Seed passport

Each batch receives a unique code.

Example:

WOOD-CH-WTZ-SEED-ML-2026-0042

The passport contains:

view;

variety or population;

batch number;

origin;

mother plants;

pollination type;

collection date;

quantity;

cleaning method;

humidity;

germination;

storage conditions;

movements;

the resulting offspring.

35. Seed storage

For each batch the following are determined:

temperature;

humidity;

package;

permissible storage period;

frequency of repeat tests;

backup storage location.

Batches cannot be stored in only one room.

Valuable samples are duplicated in an independent storage facility.

36. DREVO Seed Bank

The seed bank includes:

working collection;

reserve collection;

scientific collection;

emergency stock;

collection of local varieties;

collection of natural populations.

Working collection

Used for regular sowing and exchange.

Reserve collection

Designed to restore lost lines.

Scientific collection

Kept for research and comparison.

Emergency stock

Placed separately from the main collection.

37. Genetic fund

The DREVO Genetic Fund is a collection of living plants, seeds, tissues, pollen, documentation, and digital data that preserve hereditary diversity.

It may include:

old varieties;

local varieties;

wild relatives of cultivated plants;

natural ecotypes;

resistant seedlings;

valuable rootstocks;

mother trees;

breeding lines;

rare and endangered populations.

38. Forms of preservation of the genetic fund

On site

Preservation of plants in their natural environment.

Examples:

natural population;

old forest;

traditional garden;

natural grove.

On-farm

Preservation in the existing farm.

For example:

local varieties in the farm garden;

family seed lines;

traditional breeding methods.

From the situation

Preservation outside its natural place of origin.

Examples:

seed bank;

collection garden;

nursery;

laboratory tissue culture;

cryocollection.

The best protection is a combination of several methods.

39. Living collections

Some species and varieties cannot be reliably preserved by seeds alone.

The following are created for them:

collection gardens;

mother plantations;

clone archives;

reserve nurseries;

field gene banks.

Each valuable line should be represented by several copies, preferably in different places.

40. Clone archive

The clone archive preserves genetically close copies of specific plants.

Used for:

fruit varieties;

grapes;

berry crops;

decorative forms;

valuable rootstocks;

rare mutations;

old trees.

The material can be stored in the form of:

grafted trees;

rooted cuttings;

otvodkov;

tissue cultures.

41. Preservation of pollen

Pollen can be used for:

controlled crossings;

preservation of rare paternal lines;

pollination when flowering times do not coincide;

international exchange of genetic material.

For each batch the following are recorded:

source plant;

collection date;

drying method;

storage temperature;

viability;

pollination results.

42. Tissue culture

Tissue culture allows plants to propagate from small areas of living tissue under sterile conditions.

Advantages:

rapid reproduction;

preservation of rare material;

obtaining a large number of plants;

the possibility of improving the health of individual lines.

Limitations:

high cost;

laboratory requirements;

risk of contamination;

possible changes in culture;

the need for plant adaptation after laboratory testing.

43. Cryopreservation

Cryopreservation is used for long-term storage of:

fabrics;

embryos;

meristem;

pollen;

individual types of seeds.

It does not replace living collections, but serves as an additional reserve.

44. Digital Family Tree

Each plant in the gene pool is linked to parents and offspring.

Example:

Mother tree A

↓

open-pollinated seeds

↓

seedlings A-01 — A-100

↓

A-17 team

↓

trial

↓

new stable line

For grafted plants the following are recorded separately:

genetic line of rootstock;

genetic line of scion;

junction;

date of vaccination.

45. Genetic passport of a plant

It includes:

identifier;

view;

variety;

ecotype;

origin;

mother;

alleged or confirmed father;

method of reproduction;

rootstock;

scion;

clone line;

results of genetic tests;

offspring;

level of data reliability.

46. ​​Levels of Origin Confirmation

Level A - Confirmed Origin

There are documents, traceable pedigree and, if necessary, genetic analysis.

Level B - Well documented

Origin confirmed by nursery, mother plant and observations.

Level C - probable

There is partial information, but no full verification.

Level D - Folk or oral origin

Information is based on information provided by owners or the local community.

Level E - Unknown

Origin unknown.

Unknown origins don't mean lack of value. Sometimes these plants turn out to be rare local varieties that require further study.

47. Genetic testing

For individual collections the following may apply:

DNA markers;

genotyping;

profile comparison;

kinship analysis;

duplicate detection;

confirmation of variety;

population diversity assessment.

Molecular methods complement, but do not replace, field observations.

Two plants with a similar genetic profile may differ in their condition, epigenetic features, and response to the environment.

48. Phenotypic assessment

Phenotype is the observable properties of a plant.

Evaluated:

size;

crown shape;

leaves;

flowers;

fruit;

flowering period;

ripening period;

taste;

stability;

productivity;

stress response.

The assessment is carried out over several seasons and, if possible, under different conditions.

49. Genotype and environment

The properties of a plant depend not only on genetics.

They are formed by the interaction of:

genetic inheritance + environment + age + care + random events.

Therefore, low yield from a single tree does not always indicate weak genetics. The cause could be soil, water, root damage, poor pollination, or improper pruning.

50. Epigenetic memory

Plants are able to change the activity of individual genes in response to environmental conditions without changing the DNA sequence itself.

Some adaptive responses may persist for part of the plant's life and sometimes affect the next generation.

In the practical DREVO system, this means that it is necessary to store not only the variety name, but also information about the conditions in which the mother plant developed.

51. Local ecotypes

An ecotype is a population or form of a species adapted to specific conditions.

For example:

height;

drought;

marine aerosol;

cold winter;

early spring;

a certain soil.

Transfer of seeds from a distant region can reduce local fitness, even if it is the same botanical species.

52. Wild relatives of cultivated plants

Wild relatives may contain characteristics of:

disease resistance;

drought resistance;

frost resistance;

salt tolerance;

adaptation to poor soil;

pest resistance.

They need to be preserved as an important reserve for future selection.

53. Old and popular varieties

Old varieties may have:

unusual taste;

local stability;

cultural value;

different ripening periods;

recyclability;

ability to grow without intensive care.

They do not always meet the requirements of industrial trade, but they have high genetic, food and cultural value.

54. Selection DREVO

DREVO selection should focus not only on maximum yield.

Main objectives:

stability;

product quality;

durability;

adaptation to the local climate;

economical use of water;

disease resistance;

support for biodiversity;

suitability for multi-tiered communities;

low dependence on chemical protection.

55. Mass selection

The best specimens are selected from a large group of plants.

The method is useful for:

local populations;

forage crops;

forest species;

adaptation of seed lines.

It is necessary to avoid too narrow a selection, which reduces genetic diversity.

56. Individual selection

Each selected plant receives a separate passport.

His offspring are raised and evaluated separately.

This makes it possible to determine whether valuable traits are passed on to the next generation.

57. Family selection

Groups of descendants descended from certain parents are compared.

Evaluated:

average family indicators;

stability;

scatter of signs;

repeatability of properties;

adaptation to different conditions.

58. Controlled crossing

To create a new combination, two parents are selected.

For example:

one is drought resistant;

the other one has quality fruits.

The resulting offspring will be genetically diverse, and only a portion of the plants will combine the desired traits.

Therefore, after crossing, many years of selection are required.

59. Test sites

New lines are being tested:

on different soils;

under different irrigation regimes;

in different climatic conditions;

in various plant communities.

Compared:

survival;

height;

health;

harvest;

quality;

stability;

interaction with pollinators;

need for care.

60. Protection from genetic pollution

Genetic pollution is possible when introduced or selectively bred forms cross with rare local populations.

The following are used for protection:

spatial buffers;

flowering control;

removing flowers from unwanted forms;

separate seed production;

offspring monitoring;

maintaining clean reserve areas.

61. Prevention of inbreeding

Small, isolated collections can lose diversity.

Necessary:

maintain a sufficient number of parents;

avoid constantly collecting seeds from one tree;

take into account pedigrees;

exchange material between compatible collections;

conduct genetic assessment of particularly valuable populations.

62. Preventing variety loss

For each valuable variety it is desirable to have:

main mother tree;

several grafted copies;

reserve collection;

digital passport;

photo documentation;

description of features;

material in an independent nursery;

if possible - laboratory reserve.

63. Sanitary safety of the genetic fund

Planting material can tolerate:

viruses;

bacteria;

mushrooms;

nematode;

insects;

quarantine organisms.

Before inclusion in the collection the following are applied:

quarantine;

visual inspection;

laboratory diagnostics;

separate maintenance;

document verification;

regular monitoring.

64. Quarantine zone of the nursery

New plants are initially placed separately.

The following are recorded in the quarantine zone:

origin;

state;

symptoms;

test results;

processing;

observation period;

decision on admission.

The plant should not be added to the main mother collection until the inspection is completed.

65. Inventory of the genetic fund

At least once a year the following are checked:

presence of plants;

marking condition;

viability;

compliance with passport;

availability of backup copies;

condition of seed lots;

test results;

threats of loss.

The final principle

The gene pool is a living library of the future. Every variety, seed line, natural ecotype, and old tree may contain traits that will one day prove essential for food security, ecosystem restoration, and adaptation to a changing climate.

By preserving the origins of plants, developing seed production and passing on valuable varieties through grafting, DREVO creates a continuous connection between the nature of the past, the needs of the present and the possibilities of future generations.
