Abstract
Abstract: Egyptian clover (Trifolium alexandrinum L.) is a forage legume considered to be of high nutritional values and palatable as cattle feed. Germination of the seed is affected by water availability and environmental stress prevailing there in. Three cultivars of T. alexandrinum viz. Bundel Berseem 1 (BB1), Bundel Berseem 2 (BB2), and Bundel Berseem 3 (BB3) were germinated under varying NaNO3 and KNO3, concentration range of 0 mM, 25 mM, 50 mM, 75 mM, 100 mM, and 150 mM. Our experiment revealed that up to 50 mM salt concentration, the tested cultivars responded in similar way but when the concentration started to reach 100 mM and 150 mM significant differences between the germination rates of the three cultivars and their respective TI were found for radicle emergence, plumule emergence and cotyledonary leaf appearance. BB1 was found to be more susceptible to the salt stress and the other tested cultivars BB2 and BB3 were comparatively tolerant to salinity.
