Abstract
The effects of salinity were studied on germination of Gossypium hirsutum, Kosteletzkya virginica and Thespesia populnea under different concentrations of sea salt i.e. non saline control (ECiw: 0.4 dS.m-1 ), 0.5% sea salt (ECiw: 6.2 dS.m-1 ), 1.0% sea salt (ECiw: 12.95 dS.m-1 ), and 1.5% sea salt (ECiw: 18.90 dS.m-1 ) in irrigation medium. An increase in germination was noticed at 0.5% salinity (ECiw: 6.2 dS.m-1 ) in K. virginica and T. populnea, but germination was completely inhibited at 1.5% salinity (ECiw: 18.9 dS.m-1 ). There was regular decline in germination under increasing salinities in G. hirsutum.
