Studying plants' capability to adapt and recover from drought stress is essential because of the ever-changing nature events. To evaluate genotypically variable morpho-physiological adaptations recovery after re-watering, two wheat cultivars (Luhan-7 Yangmai-16) were pot-cultured under three levels water stress: severe (35-40% field capacity, FC) moderate deficits (55-60% well-watered conditions. Drought was applied at tillering (Feekes 2 stage) jointing 6 stage), respectively, followed by we observed changes in leaf characteristics, growth physiological activities during rewatering periods as well final grain yield traits maturity. Results showed that adaptability associated with reduced area, higher thickness, chlorophyll, dry matter maintenance potential more strongly pronounced Luhan-7 than Yangmai-16. Under both exhibited a small decrease gas-exchange chlorophyll fluorescence activities, rapid recovery. stress, Yangmai-16 displayed relatively less drought, slower re-watering greater yield. It concluded even though crop rate completely recovered outcomes affected pre-drought dependant on intensity, differences stage. also genotypic variations are indicators tolerance sustainability wheat.
