Abstract: The article presents the results on the content of chlorophylls a and b, total chlorophyll, carotenoids, water content and intensity of leaf transpiration in fine-fiber varieties and cotton lines in different conditions of water regime. Compared to optimal water availability, the content of chlorophylls “a” and “b”, total chlorophyll and carotenoids increased in varying degrees, water content and leaf transpiration intensity decreased depending on the individual genotypic response of fine-fiber varieties and cotton lines to the lack of soil moisture in the soil.
