RU1789096C - Method for presowing hard seed treatment - Google Patents

Abstract

Usage: in agriculture, in particular in crop production. SUMMARY OF THE INVENTION: In order to increase the germination capacity of hard-coated seeds, they are kept in a 1% solution of the enzyme of strain 40 obtained from the fungus Bjeriandera alusta for 48 hours. This increases the moisture content by up to 52 percent. 2 tab.

Description

The invention relates to agriculture and relates to a method for producing seedlings from seeds with hard shells.

Known methods for removing seeds from a dormant state include presowing seed treatment by means of scarification;

- chemical (grate seeds with sand, briefly treat with sulfuric acid);

- mechanical (rotation of Sem n in the drum with a gasket from carborundum);

- bacterial (activity of soil microorganisms gradually destroys the outer layer of the seed coat).

Closest to the proposed method is the effect of scarification of seeds with a hard shell of sulfuric acid on the example of soy, millet and cotton.

The known method consists in the fact that the hard shell of seeds is destroyed by exposure to sulfuric acid, which facilitates the access of water and oxygen to the embryo. As a result of chemical scarification, seed germination is 31.6% versus 12% control. Further observation of plants showed that chamois

acid affects the passage of plants through the initial stages of ontogenesis. Experienced in ariants exceed the control by 1.5-1.8 times. The disadvantages of the prototype are: a relatively low percentage of germination; insufficiently effective aftereffect of sulfuric acid on the passage of initial ontogenesis to plants: the complexity of the technological technique associated with working with concentrated acids ..

The purpose of the invention is to increase seed germination.

The goal is achieved in that as a biologically active substance using a 1% solution of the enzyme strain 40. obtained from the fungus Bjercaandera adusta, and the effect is carried out by soaking the seeds for 48 hours. The enzymatic preparation of strain 40 is described in copyright certificate No. 482494, class . Since 12 N 9 / 42,1976, authors Ganbarov H.G., Ismailov E.I., Muradov P.Z. To confirm the beneficial effect and determine on-. Under optimal conditions, the following experiment was carried out. Seeds were pre-sowed by the enzyme in concentrate VI 00 45

After the specified time, the seeds were washed in distilled water, mixed with sand 1: 1 and sown on pre-prepared basalt wool. Sprouts exposed to continuous light. Watering was carried out every other day, in a series of Knop solution and distilled water. The data obtained are presented in table.1.2. Studying the effect of a wide range of concentrations of strain 40 enzyme and exposure time showed a significant dependence of the percentage of seed germination on these parameters. As can be seen from the data presented in Table 1, the optimal solution is a 1% solution after 48 hours pre-sowing soaking. The obtained version gives a 1.7-fold superiority in seed germination in comparison with the method of scarification using sulfuric acid. The data presented in table 2 indicate that the most intensive development

characterized by plants obtained from seeds treated with a 1% solution of the enzyme for 48 hours.

The use of an enzymatic scarifier allows one to increase the germination of seeds with a hard shell, and also has a consequence on the passage of plants through the initial stages of ontogenesis. This approach increases the efficiency of reproduction of solid seeds and has a significant advantage over the known methods of scarification. ..-.;. x. SUMMARY OF THE INVENTION

A method of pre-sowing treatment of seeds with a hard shell, including exposure to a biologically active substance on them, with the exception of purpose and purpose. To increase germination, as a biologically active substance use a 1% solution of the enzyme strain 40, obtained from the fungus Bjercandera adusta, and the effect is carried out by soaking the seeds for 48 hours.
