Abstract:
Numerous metabolic functions, including photosynthesis, endure detrimental consequences under drought-stress conditions. As a fact, water scarcity harms the plants' fundamental components, which prevents carbon assimilation and harms the photosynthetic machinery. In this regard, the present research was conducted to study chickpeas' photosynthetic efficiency (PSII efficiency) under restricted moisture levels. We found that six chickpea genotypes differing in their behavior towards depleting soil moisture levels viz., 60, 50, 40, 30, and 20% FC evaluated for PSII efficiency. Water stress substantially decreased the leaf PSII efficiency in all the genotypes under soil moisture depletions. The G1 had more PSII efficiency than the other genotypes under severe soil moisture depletion. However, at the same moisture level, the G4 genotype had lower PSII efficiency than the rest of the genotypes.
