Abstract

FIELD: agriculture.SUBSTANCE: extract, which is composed of the intravital secretions of the plants, and of the exometabolites received by chopping, is used for processing, and then the Cladonia rangiferina blastema water extractions at the rate of 250 gram per 1 litre of water are used within 24 hours. The processing by the aqueous extract of the lichen is accomplished through the seeds-soaking treatment at exposures in the solution within 24 hours at a temperature of 20±2°C.EFFECT: scotch pine seeds germination high speed, roots and germ plants growth acceleration and its immunity to the bacterial and fungal diseases enhancement.1 tbl

Description

The invention relates to forestry and can be used for growing planting material of ordinary pine during pre-sowing preparation of seeds for sowing.

The invention relates to forestry and can be used in the cultivation of planting material of ordinary pine in nurseries and selection and seed centers, forestries and household plots for presowing seed preparation.

The closest analogs (prototypes) are methods for pre-sowing seed treatment of common pine, including seed treatment with preparations obtained on the basis of plant material extract based on shoots and needles of juniper, zircon. The disadvantage of extracts based on shoots and needles of juniper is the increasingly shrinking area of common juniper, therefore, the difficulty of harvesting and storage in sufficient quantities of biological material. The disadvantages of drugs, such as zircon, are their low efficiency in stimulating growth processes, in relation to the seeds of forest and shrub crops. In addition, the above drugs are obtained chemically, or produced by irretrievable removal of biological materials from the environment [1].

The aim of the invention is to increase the energy of germination, germination of seeds of ordinary pine, thereby increasing the quality class of seeds under the condition of a lack of planting material during artificial regeneration, accelerating the growth and resistance of seedlings against bacterial and fungal diseases.

The technical result obtained by the implementation of the invention is to provide a high rate of germination of common pine seeds, accelerate the growth of roots and seedlings and increase their resistance to bacterial and fungal diseases (Fusarium and others).

The technical result is achieved by the fact that the method of stimulating the germination rate of common pine seeds involves pre-sowing treatment of common pine seeds, according to the invention, an extract containing intravital plant excretions (exametabolites) obtained by grinding and then extraction with water at a rate of 250 g per 1 is used for processing liter of water for 24 hours of the thallus of the lichen Cladonia rangiferina, treatment with an aqueous extract of lichen is carried out by soaking the seeds with aging in solution for 24 hours at a temperature of 20 ± 2 ° C.

Presowing treatment of pine seeds with an ordinary extract of the thallus of the lichen Cladonia rangiferina with an extract containing biologically active substances and secondary metabolites: fumarprotetzetrovoy acid, atranorin [2], which accelerate the increase in seed germination rate, soil germination and germination resistance against fungal diseases and the development of bacteria. The thallus of the lichen is taken in its natural (non-dried) state, crushed and then extracted with water at the rate of 250 g per 1 liter of water for 24 hours. Treatment with an aqueous extract of lichen is carried out by soaking the seeds with aging in solution for 24 hours at a temperature of 20 ± 2 ° C. The use of a solution at the rate of 2 liters per 1 kg of ordinary pine seeds.

Application example

When germinating seeds, measurements were made of the length of the seedlings grown from the treated seeds, as well as germination and germination energy compared to control seeds soaked in distilled water. The research data are given in table. one.

The use of the invention helps to increase the energy of germination, germination of seeds of ordinary pine, thereby increasing the quality class of seeds, provided there is a lack of planting material with artificial reforestation, accelerate the growth and resistance of seedlings against bacterial and fungal diseases.
