Abstract

The growth and osmotic adjustment ability of four black locust clones were studied .The results showed that drought stress inhibited the growth of Robinia pseudoacacia clones , increased their soluble sugar as well as membrane permeability and content of proline , and decreased their water potential .Research found that R . pseudoacacia had strong ability to automatically adapt to drought stress , but the four clones had different pattern of adaptation .W1 and L1 protected cell membrane stability by increasing their activities of superoxiede dismutase (SOD), catalse (CAT)and peroxidase (POD), but L59 and L78 did so by improving their activities of SOD and CAT .W1 and L1 were more sensitive to drought stress than L59 and L78 .The osmotic adjustment ability of black locust clones was almost irrelative to its growth and injury of cell membrane .[ Ch , 5 fig .3 tab .20 ref .]
