Abstract
The effect of salt stress was studied on physiological, biochemical and molecular
parameters in different genotypes viz. Kent, OL-10, OL-1862, OL-1869, OL-125, OL-
1966, OL-1876, OL-1895 of oats (Avena sativa L.). When seeds of oats were subjected
to different salt concentrations ( at 25mM, 50mM, 75mM, 100mM, 125mM, 150mM,
175mM, 200mM) of NaCl, various physiological parameters such as shoot
length(lamina and sheath), root length, dry weight, fresh weight, seed vigour I, seed
vigour II declined with the increase in salt stress level in all the genotypes whereas the
biochemical parameters such as total soluble sugars, total protein content and activities
of antioxidant enzymes increased with the increase in salt stress level in all genotypes.
