SU512691A3 - Plant growth regulator - Google Patents

Description

one

The invention relates to chemical means of regulating physiological processes in plants to accelerate their flowering, ripening, increase or retard growth, which ultimately contributes to an increase in yield and a new quality of agricultural products.

It is known to use as a plant growth registrant of sulfinic acid derivatives of the general formula (1)

leaflets n ripening is proposed to use as the plant growth regulator arsenic 2-halogenoethanesulfinic acid of general formula (U1)

Example 2. Peanut seeds in the germline age — After 2 days, the number of seeds is counted and treated with compounds of the general formula (III) grown seeds (in pieces) in comparison with the control and the known compound as a reference. Table 2 shows the results. 2

Example 3. Slowing down the aging of barter.

The primary leaves of barley cut into segments; . , 1 cm long and treated with compounds of the general formula. in in various concentrations. Growth regulators cause yellowing of jmcTbeB segments. After 4 days, slowing down of aging is determined and is assessed on a scale:

O - there is no slowing down of aging;

+ - slight slowing of aging;

- and - strong aging slowdown;

+++ - a strong slowdown in aging
