【 摘 要 】

To study the influence of temperature and growth regulating substances on seed germination, kiwi seeds stored at 4°C refrigerated for 55 days were used as experimental materials. The treatments were set as below: (1) poikilothermal (25°C 8h/4°C 16h) or constant temperature (25°C 24h) treatment; (2) treated with melatonin and gibberellin under constant temperature; (3) treated with melatonin and gibberellin under poikilothermal. The germination rate and germination potential of the treated seeds were analyzed statistically. The results showed that the germination rate of seeds could be increased by poikilothermal treatment, especially for the variety MW2, and the germination rate reached to 86.86%. Under constant temperature, gibberellin had a significant effect on the germination of kiwi seeds, while melatonin had no effect. Under the condition of polikilothermal, gibberellin and melatonin treatment alone can obviously promote the germination of kiwi seeds, while the application of gibberellin and melatonin at the same time can promote the germination of kiwi seeds, but there was no synergistic effect.
