Sp. act. of RNase in shoots increased in IS. at - 5 bar JI
while in TKM-1 it remained more or less the same.
Further increase in water stress resulted in decrease in
enzyme activity in I.S. shoots. The ratio of RNase A/B
did not change much during water stress. RNase sp. act.
decreased in TKM-1 roots with increase in water stress
while in IS. it showed an increase up to - 10 bars JI and
a slight decrease thereafter. The RNase A/R ratio decreased
at - 15 bars $ in TKM-1 roots while in I.S. it
remained more or less the same.
