Description

: o: p lU 1.1 The invention relates to agriculture and can be used in the presowing treatment of seeds. It is known to use as a stimulant in presowing treatment of seeds of succinic acid l. It is also known to use calcium 3-deoxy-2-hydroxymethyl-B-pentonate as a stimulant. However, the use of these stimulants is expensive and ineffective. The aim of the invention is to increase the effectiveness of stimulating seed germination and increase yields. The goal is achieved by using the calcium salt of 2-C-methyl-D-ribonic acid of the formula (EMA) n n n, (NOSHgC-C-C-C-0). Ca f I I In OH OH ON 74 as a stimulant for presowing treatment of seeds. This compound is obtained by the action of alkali on hexoses h. fi p and me R 1. Seeds of haricot variety Tsanava-3 (100 pieces in each experiment) are soaked in aqueous solutions of the preparation at a concentration of 0.000005-0.05% for 24 hours at 20 C. Control - soaking seed in water at the same mode. Next, the seeds are washed with running water and grown in a thermostat. Accounting for germination is carried out on the fourth and eighth day. The test results are presented in Table. 1. Table 1

From tab. As can be seen in Figure 1, preplant treatment of bean seeds in dilute solutions of the drug increases the germination energy by up to 64%, and germination up to 61%.

Harvest of beans (seed weight) of Tsanava-3 increased by 46-62% (23.4 and 26.0 c / ha instead of 16 c / ha) when processing the proposed compound, while pre-sowing treatment with beans with succinic acid increases yield of 4.3%, and 3-dedoxy-2-C-hydroxymethyl-B-calcium pentonate 40% (Table 2).

It should also be noted that the proposed compound is much lower in comparison with the known doses and has the maximum stimulating effect.

In contrast to the known stimulators, the proposed approach markedly increases plant resistance to external agents. For example, before sowing

Example 2. The use of the proposed compound is also effective for increasing the corn yield. The processing of these seeds is carried out as in Example 1. The corn crop of the Kartuli variety has increased by 29.6%. Harvest is not only due to

It should also be noted that the chemical composition of the yield of the treated seeds is distinguished by a higher quality (see Table 3).
