Abstract:
Four-year-old‘Zhongnongjinhui’peach was taken as material.The effects of defoliation periods and ways on germination rate under the way of cultivation with non-chilling accumulation on facilities nectarine were studied.The results showed that under the way of cultivation with non-chilling accumulation on facilities peach,the effects of different defoliation periods on germination rate was different.The germination rate gradually increased from August,the highest germination rate was occurred on mid-to-late of September,since then declined gradually,the germination rate was declined to zero on the end of October.The effects of different defoliation ways on germination rate were also different,among the three defoliation ways,the germination rate was the highest in the defoliation model away from light,the difference was very remarkable compared with artificial leaf picking and defoliation by 8% urea.So,the best defoliation period was screened out on mid-to-late of September under the way of cultivation with non-chilling accumulation on facility peach,and the best defoliation model was away from light.
