Physiological Characteristics of Soybean Varieties Under Meadow-Alluvial and Water-Deficit Soil Conditions of The Bukhara Region

This article presents experimental data on the physiological indicators that determine stress tolerance in soybean varieties under varying soil moisture regimes (optimal, limited, and arid/drought). The study reveals that changes in these physiological parameters are significantly influenced by soil moisture levels, plant developmental stages, and the unique biological characteristics of each variety. Specifically, the dynamics of cellular turgidity, water-binding capacity, and catalase enzyme activity were analyzed to evaluate the adaptive mechanisms of soybeans under water-deficit conditions. The findings provide insights into selecting resilient cultivars for cultivation in the meadow-alluvial soils of the Bukhara region.
