The activities of SOD in unprimed and primed plants were markedly
increased with the increasing drought stress levels. SOD activities in
primed seedlings were higher than that in non-primed one both normal
and stress conditions (Table 1). The results indicated that SOD activity
was significantly negatively correlated with the germination percentage
(r=−0.736,pb0.05), potential (r=−0.632,pb0.01) and vigor index
(r=−0.642,pb0.05)
