SU818584A1 - Plant growth stimulant - Google Patents

Description

The invention relates to the field of agriculture and can be used in the regulation of plant growth.

It is known to use various organic compounds as plant growth stimulators, such as heteroauxin 1, o-mentadiene-3,6 2.

However, these plant growth regulators do not have a sufficient stimulating effect.

The aim of the invention is to increase the stimulation of plant growth and development.

The goal is achieved by using o-menthadiene-1,4 of the general formula:

Cucumber variety B Znikovsky 37 was soaked in a solution of o-mentadien-1,4 for 24 hours. Treatment of seeds in solutions of o-mentadien-1, 4 increased the germination energy and increased the germination rate of the seeds of these crops (Table 1).

as a plant growth regulator.

The o-mentadiene-1,4 fraction is obtained by distillation in a vacuum on a column of 90 theoretical plates of the product of the interaction of o-cymol with calcium hexaamyamoate in the presence of tertiary butyl alcohol 3.

Example 1. Seeds of winter wheat varieties Mironovska 808, white cabbage varieties Number One Gribovsky 147 and

Example 2. Seeds of radish varieties Rubin soaked before sowing in a 0.001% 30 solution of o-mentadien-1,4 for 12 hours

In radish plants under the conditions of vegetative and field experiments, growth stimulation and an increase in the yield of biomass and root crops were observed (Table 2).

Example 4. Plant seeds of barley variety Beam were treated before sowing with a 0.001% aqueous solution of o-mentadien-1, 4 at a rate of 10 l per 1 centner of seed. Seed treatment with a solution of o-meitadiene-1, 4 increases the length of the ear, accelerates filling and ripening for 2-3 days and increases the grain yield (Table 4).

Example 3. Hop varieties Moscow early (30-6) were sprayed with a 0.01% aqueous solution of o-mentadnene-1, 4 during the budding period at the rate of 1000 l of the working solution per hectare, in the period before budding.

The treatment of hop plants with a solution of O-mentadiene-1,4 facilitated intensive growth, increased the yield of checkers and increased the content of bitter plants in them (Table 3).
