Certain Physiological Characteristics of Water Metabolism in Local and Foreign Cotton Varieties Under Soil Salinity Conditions

Abstract

This article presents comprehensive data obtained regarding the water metabolism of local and foreign cotton varieties cultivated under conditions of soil salinity. It provides a detailed substantiation of the variations in water metabolism rates across the local Bukhara-8 variety and several foreign varieties, specifically Xinluzao-57, Zhongmian-88, Xinluzao-52, Zhongmian-113, Xinluzao-78, and Zhungtay-2, within both control and experimental variants. The investigation established that the critical physiological parameters defining the water metabolism characteristics of cotton − namely, the water-retaining capacity of the leaves, the intensity of transpiration, and the diurnal leaf water deficit − exhibit a direct and significant dependence on the specific variety, the experimental conditions, and the developmental stages of the cotton plants.
