Abstract

Alpha-amylase, protease, reducing sugars, non-reducing sugars, protein and total amino acids were studied in
seedlings of 4 wheat genotypes, for a period of 96 hrs. after sowing, under stressed and non-stressed conditions. It
was observed that u-amylase, protease, reducing and non-reducing sugars and total mino acids increased in all the
genotypes subjected to -0.6 MPa water stress. The genotypes Chakwal-86 and DS-4 showed the highest a-amylase
activity, sugars and total amino acids. On the other hand DS-17 and Pavon showed higher protease activity than the
others. The highest reduction in protein content was recorded in DS-17 andPavon. The significance of these findings
is-discussed.
