Genotypic differences in water status, membrane integrity, ionic content, N2-fixing efficiency and dry matter of mungbean nodules under saline irrigation.

A pot experiment was conducted under natural conditions of screen house to evaluate the effect of saline irrigation given at flowering stage (30-35 DAS) on nodule functioning and their tolerance in two mungbean genotypes viz. Asha and Muskan based on various physiological traits. The pots containing sandy soil (Typic Torrispamments) were saturated with Cl-dominated saline irrigation to maintain ECe of 2.

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.

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.
