Abstract
Vigna is a genus of flowering plants in the legume family, Fabaceae with worldwide distribution. In the present study, effect of salt stress was investigated in four species of Vigna viz. V. mungo (urd), V. angularis (rais), V. radiata (moong) and V. aconitifolia (moth) at germination and seedling growth stages in a glasshouse experiment. Seeds of selected crops were surface sterilized and placed under three salt stress levels of 0 (control), 50mM and 100mM using NaCl solutions. Three replicates for each treatment was used for this experiment. The results indicated that increase in salt stress levels caused a reduction in germination percentage, germination rate, shoot length, root length and seedling dry weight of each Vigna species. The overall results indicated that among the four species, V. aconitifolia was the most sensitive, whereas V. mungo was the least sensitive species to the salinity in almost every aspect of growth.
