Gas exchange and leaf water relations in two peanut cultivars of different drought tolerance

Year: 1995

Type: article

Abstract: In summer seasons of 1991 and 1992 the gas exchange and leaf water relations were analysed in two peanut cultivars: drought tolerant cv. GG 2 (DT) and drought sensitive cv. JL 24 (DS). Soil moisture stress was imposed by withholding irrigation at pod development phase. The decrease in photosynthesis (PN) under stress was associated with a decrease in stomatal conductance (gs) and relative water content (RWC). The PN and RWC were significantly higher under stress in DT than DS. On relief of stress the gs and RWC recovered more quickly in DT than DS. The maintenance of higher RWC (>80 %), gs and PN under stress appears to be imparting drought tolerance in peanut.
