The activity of CAT in primed and non-primed Chinese cabbage
seedlings increased with elevating drought stress levels and then
decreased at higher levels of drought stress (Table 1). CAT activity in
unprimed, hydroprimed, KNO3and urea primed seedlings peaked at
−2.0,−3.0 and−1.0 MPa, respectively (Table 1). Results indicated
that CAT activity was positively correlated with the germination
percentage (r=0.468,pb0.01)
