Abstract: In order to explore the effect of drought and rewatering on growth and drought resistance of silver edge ivy， the changes of growth and some physiological indexes were studied. The results showed: comparing with the control， the growth rate of the longest caulis and increment rate of leaf in each treatment decreased in varying degrees， the relative plasma membrane permeability and proline content increased in varying degrees. The chlorophyll content and root activity under the severe stress significantly increased compared with the control， but there was no difference in chlorophyll content and root activity among other treatments. After rewatering， chlorophyll content， the relative plasma membrane permeability and proline content of the treatments were decreased to the normal level， but root activity was higher than the control. The results indicated that the survival of silver edge ivy was not threatened under drought stress condition in this experiment.
