摘要
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％。
The effects of maturities and pre harvest treatments on storage performance of peaches ( Amygdalus persica cv. Okubao,A.p. cv Jingyu and A.p .cv Yanhong )were studied. The results showed that maturities could affect the storage performance directly. Fruits harvested at green mature stage,the surface color and fruitfirmness were maintained very well during storage,the rates of pulp brown and storage rot was much lower than the fruit harvested at the ripe stage. Pre harvest treatment with 100 mg/kg GA 3 could enhance the storage performances. The storage rot was reduced if the orchards were sprayed with funglcides such as rovral flo (500 mg/kg) 1 or 2 days before harvest. Another pre harvest treatment reagent (50 mg/kg GA 3,50 mg/kg 2,4 D and 2 000 folds carbendazim) was also sprayed in orchards 10 days before harvest,the treated fruits retarted their physical and chemical metabolism,so that maintained the fruits quality well and reduced the rates of rot and the pulp brown during storage.
