INFLUENCE OF SEEDS INCRUSTATION BY N-PHOSPHONOMETHYLGLYCINE AND EPIBRASSINOLIDE MIXTURES ON THE PLANT GROWTH
Abstract
The dependence of action of an inhibitory dose of N-phosphonomethylglycine mixed with epibrassinolide over a wide concentration range, on the root growth of flax (Linum usitatissimum L.) and barley (Hordeum vulgare L.) seedlings is studied. Specific and varietal specificity of growth responses to the incrustation of seeds by such mixtures is identified. The epibrassinolide concentration range, in which its interaction with N-phosphonomethylglycine is most expressed, is detected. It is characterized by the intensification (in spring barley seedlings) or the weakening (in flax seedlings) of the inhibitory effect of glyphosate on the root system.
