Standardization of mango rootstock for mitigating salt stress

Abstract

Seedlings of different mango varieties were tested against different EC levels of water developed by several salt compositions. Seedlings from stone of Kesar variety was found better with significantly highest survival percentage, germination percentage and growth parameters. Significantly more mortality of seedling was observed in Totapuri variety. In case of EC level of water, significantly highest survival percentage was registered only at 1.20 dSm-1 EC level. Poor seedling survival (14.12%) could be‘ recorded at 4.00 dSm-1 EC level of water. Germination percentage, number of leaves, plant height and root length were increased with decreasing EC level. The accumulation of sodium was found to be higher in leaves, whereas, potassium and Na: K ratio were noted lower with higher EC level. The interaction effect of days to germination, number of leaves, root length, survival percentage, Na content and Na:K ratio were found significant.
