Plant water status, ethylene evolution, N 2-fixing efficiency, antioxidant activity and lipid peroxidation in Cicer arietinum L. nodules as affected by short-term salinization and desalinization
Abstract
Salinity induced changes in ethylene evolution, antioxidant defense system, N 2-fixing efficiency and membrane integrity in relation to water and mineral status in chickpea ( Cicer arietinum L.) nodules were studied under screen house conditions. At vegetative stage (55–65 DAS) plants were exposed to single saline irrigation (Cl ‑ dominated) of levels 0, 2.5, 5.0 and 10.0 dS m ‑1 and sampled after 3 d. The other set of treated plants was desalinized by flooding and the plants were sampled after further 3 d. Water potential (
