桃的采收成熟度与果实的耐藏性有较密切的关系。在７～８成熟时的绿熟期采收，经贮藏后果面新鲜，果实硬而脆，褐变和腐烂少；采收过晚则果实易软化，容易褐变和腐烂。采前１个月用１００ｍｇ／ｋｇＧＡ３处理有利于提高桃果实的耐藏性，贮藏后处理果的硬度比对照高１倍；采前１～２ｄ用５００ｍｇ／ｋｇ朴海因处理大久保、京玉和燕红桃，贮藏好果率分别增加２２．８％，２２．９％和１８．３％；采前用混合液（ＧＡ３５０ｍｇ／ｋｇ，２，４－Ｄ５０ｍｇ／ｋｇ，多菌灵２０００倍）处理可减慢桃果实在贮藏期间的生理代谢，并能较好地保持品质，腐烂和褐变指数分别比对照降低７．７％和４．０％。
Peach harvest maturity and fruit storage resistance are more closely related. Harvested at the ripening stage of 7 ~ 8 ripening, fresh fruit after storage, the fruit is hard and brittle browning and decay less; the harvest is too late, the fruit is easy to soften, browning and decay easily. The treatment with 100mg / kg GA3 for 1 month before harvest was helpful to improve the storability of peach fruit. The hardness of postharvest fruits was 1 times higher than that of the control one month before harvesting. Yan Hongtao, the stored good fruit rate increased by 22.8%, 22.9% and 18.3%, respectively. Before harvesting, the mixture was treated with GA350mg / kg, 2,4-D50mg / kg and carbendazim 2000 times Can slow down peach fruit physiological metabolism during storage, and can better maintain the quality, decay and browning index decreased 7.7% and 4.0% respectively compared with the control.
