Abstract:: ‘Xizhoumi No.25’ hami melon was used as materials，change of free proline，betaine，soluble sugar，chlorophyll，malondialdehyde and enzyme activity of melon were tested under drought stress in this study.The results showed that the proline content changed little in the early，but proline content increased rapidly since 5 days and was significantly higher than CK，betaine content changed smoothly and was always higher than CK,soluble sugar content increased in the early and declined in the later，alondialdehyde content increased，chlorophyll a and carotene contents declined in the early and increased in the later，but chlorophyll b was opposite，they did not change obviously in the later and was higher than CK，POD and SOD activity first roughly fell then rose，and were slightly higher than CK after 5 days.
