Abstract

This article examines recent advancements in research concerning the physiological mechanisms underlying sorghum crop growth under diverse abiotic stress conditions. Photoperiod sensitivity and photosynthesis are critical determinants of sorghum development and productivity, governed by multiple environmental and hormonal factors. Sorghum is significantly influenced by abiotic stresses such as drought, extreme temperature fluctuations, and salinity, which impact both growth and physiological parameters. Substantial progress has been made in identifying sorghum genotypes with enhanced resistance to these stressors, as well as elucidating the physiological, biochemical, and molecular processes involved in such resistance. The accumulation of osmolites including HCN, proline, ABA, HPSs, and betaine plays a pivotal role in improving tolerance to drought, temperature stress, and salinity. The selection of straightforward traits, such as seedling glossiness and sustained leaf greenness during severe drought, represents significant advances in breeding. Implementing proper agronomic practices is advocated to mitigate crop stress. A comprehensive understanding of the physiological basis of sorghum growth and its application in breeding strategies is essential for maintaining crop productivity and resilience under various stress conditions in the semi-arid tropics.
