SU1207412A1 - Method of presowing treatment of seeds with deep organic dormancy - Google Patents

Description

The invention relates to agriculture, crop production, and in particular to methods of pre-sowing seed treatment.

The aim of the invention is to reduce the period of germination of seeds, the increase in germination and germination energy.

Example. Freshly harvested fruits PanaKginzeng S.A. Meu, which are characterized by deep organic dormancy and therefore require a two-story (thermal and cold) stratification, are immersed in the bath jc with warm (22-25 s) activated water and remove them from the pericarp. Part of the fruit for control is treated with activated water at room temperature (18 ° C). Then, dried and ventilated, the seeds are placed in clay vessels, mixed with moistened sand. They are held in vessels for 3-3.5 months. at an air temperature of 18-22 C (thermal stratification). Then the temperature drops and the seeds are 3.5-4 months. and, practically, before sowing into the ground, they are kept at an air temperature of O - C C (cold stratification).

In the control group, stratification was carried out with ordinary tap water under the same temperature conditions.

After 2 months after the beginning of stratification, the number of seeds disclosed was taken into account monthly. Seeds that have undergone a two-stage stratification. were sown in the ground.

The obtained statistics are summarized in table. L (heat stratification) and 2 (cold stratification).

As a result of seed treatment with activated water, taken at room temperature, all indicators increased by 2-3, and sometimes 4 times (germination energy, number of seeds ready for sowing, germination, etc.), and during stratification With heated activated water, indicators are still available. Thus, when the temperature of the activated water 22 — the seed germination energy increased to 87%, the laboratory germination rate of 96.6%, the damage to diseases decreased to zero, the germination period of the seeds decreased to 6.9 months. A further increase in temperature adversely affects the sowing qualities of seeds.

Consequently, the optimal temperature regimes of the activated water used for warm stratification are 24 -, and for cold stratification 20–22 ° C.

Of great importance is stratification by activated water to preserve the gene pool of rare and endangered (listed in the Red Book) plant species. Thanks to this method, it is possible to grow plants from seeds whose storage period has expired or the germination period does not correspond to the growing season of this species.

The proposed method is easy to use for mass growing and expanding the range of useful plants, when introduced from different geographic areas, which expands the raw material base.

METHOD FOR PRE-SEED TREATMENT OF SEEDS WITH A DEEP ORGANIC UNDERSTANDING, including preliminary preparation, soaking with water, warm and cold periods of stratification, characterized in that, in order to reduce the period of seed production, increase germination and germination energy, the soaking of seeds is carried out in an activated genus with a pH of 8-10 obtained by electrolysis, while in the warm period of stratification, the water temperature is maintained at 24-25 ° C, and in the cold period - 20-22 ° C. · ABOUT
