Abstract: | The influence of a number of defoliants on the gossypol pigments of cotton seeds of variety S-4880 has been studied. It was established that the qualitative compositions of the pigments of the defoliant-treated plants and of the control plants were identical. However, their quantitative composition in seeds treated with defoliants having a severe action had changed substantially: they contained larger amounts of the bound forms of gossypol than in the variants with defoliants having a mild action.Institute of Chemistry of Plant Substances, Uzbekistan Academy of Sciences, Tashkent.
