Salinity tolerance is one of the important abiotic stresses that damages crop growth. In order to study the effect of saline on germination and seedling attributes, four cultivated varieties of greengram were subjected with five levels of salinity viz., 0, 4, 8 and 12 ds/m. Genotypic variation was observed for germination and seedling characters among the varieties. The experimental results revealed that with increase in salinity levels, greater reduction was observed for all the parameters. Germination per cent, seedling length, shoot, ischolar_main and total dry matter production, seed vigour and salt tolerance index were found reduced in all the varieties studied with more reduction at higher salinity (12 ds/m) level rather than other lower salinity levels and shoot ischolar_main ratio was found increased with increase in salinity.

Abstract


Salinity tolerance is one of the important abiotic stresses that damages crop growth. In order to study the effect of saline on germination and seedling attributes, four cultivated varieties of greengram were subjected with five levels of salinity viz., 0, 4, 8 and 12 ds/m. Genotypic variation was observed for germination and seedling characters among the varieties. The experimental results revealed that with increase in salinity levels, greater reduction was observed for all the parameters. Germination per cent, seedling length, shoot, ischolar_main and total dry matter production, seed vigour and salt tolerance index were found reduced in all the varieties studied with more reduction at higher salinity (12 ds/m) level rather than other lower salinity levels and shoot ischolar_main ratio was found increased with increase in salinity.
