Peroxidase
Sp. act. of peroxidase in TKM-1 and I.S. in 72 hr
imbibed seeds and I-day-old shoot and root at different
water stress is shown in Table 1. At 72 hr imbibition sp.
act. of peroxidase decreased with increasing moisture
stress both in TKM-1 and I.S. The decrease in I.S. was
74% while in TKM-1 it was only 37 %. Peroxidase
activity did not change much in the shoots of either
variety. In roots of TKM-1 also peroxidase activity
increased with moisture stress while in IS. roots it
decreased. These observations further support the greater
decrease in peroxidase isoenxyme bands [5] and their
intensities in IS. as compared to TKM-1
