Physio-biochemical parameters were recorded under moisture stress and normal condition of tolerant and susceptible cotton G. hirsutum genotypes, when plants experiencing moisture stress at 65-67 DAS (15-17 days of water withholding and 80-82 DAS (30 days water withholding). The genotypes, Khandwa-2, F-2226, RAJ-2, Bikaneri nerma, PH1009, CCH1831 and 5433A2A03N83 were found to exhibit one or more than one physiological parameters towards tolerance to higher RWC, less reduction in photosynthetic rate, stomatal conductance and transpiration rate with higher canopy temperature in drought tolerant genotypes than susceptible MCU-5. Similarly biochemical traits like higher proline and peroxidase enzyme activity play important role in exhibiting drought tolerance under moisture stress condition. | Effect of physio-biochemical factors influencing moisture stress tolerance in cotton (Gossypium hirsutum L.)
