Description

I

The invention relates to the field of agriculture, in particular to synthetic plant growth regulators.

It is known to use as regulators of physiological processes in plants x-gibberelpine, heteroauxin, synthetic analogues of auxins, acetal of unsaturated cyclic formyl derivatives of fl}, and also mixtures of unsaturated bicyclic formyl derivatives 2.

However, they were not widely used due to the complex technological process, their production, due to the high cost and insufficiently high stimulating effect.

The aim of the invention is to expand the range of effective plant regulators.

This goal is achieved by using tri- (E-chloroethyl) phosphate as a plant growth regulator, which was previously used as a plasticizer in the production of cellulose cellulose cellulose materials.

Example 1. In laboratory conditions in 1977, the seeds of a variety Grenovsky Gribovsky-1180 tomato variety, white cabbage variety Gribovsky-147 No. 1 and Strygunovsky variety onions are soaked in solutions of tri- (|) -chloroethyl) phosphate, gibberellin or water ( control) for 12 hours and

The s are then germinated to determine the germination and germination energy according to the method of state variety testing of agricultural crops (Table 1).

Under the influence of presowing treatment of seeds with 0 | 005% aqueous solution of tri- ({L-chloroethyl) -phosphate, both prostakid energies and an increase in laboratory germination of seeds are observed.
