Fluctuation in Germination on Exposure to Salt Stress in Trifolium Alexandrium L. in Cultivars

Abstract

Trifolium alexandrinum L. is a leguminuous plant having tremendous nutritional values associated with it to be utilized as cattle feed. The germination is affected by different factors and one of them being the water absorption capacity of seeds for initial germination. In our study three cultivars of T. alexandrinum viz. BB1 BB2 BB3 were selected and their corresponding seeds were germinated under Na2SO4 stress. The salt concentration chosen for the study ranged from 0 mM, 25 mM, 50 mM, 75 mM, 100 mM, and 150 mM. The study revealed that the salt concentration 0 mM, 25 mM, 50 mM were not having pronounced effect but upon increasing the salt concentration the rate of germination decreased and hence the radical, plumule and cotyledonary leaf also was drastically reduced
