A pot experiment using sandy soil was conducted under natural conditions of a screen house to assess the effect of different levels of soil salinity (0, 2, 4, 6, 8, 10, 12, 16 and 20 dSm-1) on germination and vegetative growth of Albizia lebbeck and Melia azedarach with an objective to tet their tolerance on the basis of germination and seedling growth. The germination percentage of both the species reduced significantly with the increase in salinity level beyond ECe 2 dSm-1. There was substantial reduction in shoot, root growth and dry weight with the increase in salinity levels and M. azedarach was most adversely affected as compared to A. lebbeck. Saline treatment significantly reduces the dry weight of seedling and maximum per cent reduction was observed in M. azedarach suggesting sensitivity of this plant to high salinity. It is concluded that increase in salinity adversely affect the growth of seedling of both the tree species. Salt tolerance was better in A. lebbeck than M. azedarach as found from the germination and growth parameters.
