【 摘 要 】

In order to study the effect of exogenous melatonin (MT) on breaking the dormancy of kiwifruit seeds, in this experiment, the kiwi fruit seeds were kept at 4°Cfor 15 days. At the same time, we used different concentration gibberellin (GA) and MT solution to treat the seeds, and calculated germination rate (GR) and germination potential (GP) of seeds. Compared with the control treated with water with no any germination (CK), MT treatments promoted the GR to 10%-16%, and the GP increased to 4%-7%. And 50μmol/L MT treatment had the best results, with 16% GR and 7% GP respectively. GA treatments promoted the GR to 15%-30%, and the GP increased to 8%-12%. And 50μmol/L MT treatment had the best results, with 30% GR and 12% GP respectively. The results showed that MT and GA may have some effects on breaking kiwi seed dormancy, and GA had better effect.
