GROWTH RESPONSES OF SEEDLINGS OF CERTAIN SPICIES AND CROP VARIETIES IN TREATMENT GLYPHOSATE (N-PHOSPHONO-METHYLGLYCINE)
Abstract
Physiological effects of low doses of glyphosate are studied on the seedlings of three different crops – spring barley, flax and winter rape. The dose-response dependence is found for each culture in a wide range of concentrations of N-phosphonomethylglycine. Specific and varietal specificity of growth responses to incrustation of seed by glyphosate is identified.
