2、生物保鲜剂)的7个处理结合冰温贮藏果实,以空白处理为对照,每隔30d测定冬葡萄的品质指标1次,连续测定5次。【结果】随着贮藏期的延长,巨峰冬葡萄果实脱粒率、pH波动上升,好果率波动下降,可溶性总糖(Ts)含量先升后降,可滴定酸(TA)、可溶性固形物(Tss)和维生素c(Vc)含量均有不同程度降解和损失。果实贮藏至5个月,化学保鲜剂处理的好果率均保持在85.oo%以上,对照处理的好果率降至13.66%;各保鲜剂处理的Ts、Tss和vc含量均显著高于对照处理(P<0.05,下同),化学保鲜剂处理的TA含量显著高于对照处理。生物保鲜剂处理在短期贮藏(0~3个月)呵显著保持果实品质。
3、【结论】保鲜剂结合冰温贮藏可有效保持采后巨峰冬葡萄的品质,最佳贮藏期为0~3个月。关键词:保鲜剂;巨峰;冬葡萄;贮藏保鲜;果实品质中图分类号:S663.1文献标志码:A文章编号:2095一“91(2014)12—2236一06Effectsofdif托rentfIresh—keepingtreatmentsonqualityofGuangxi、)l,interKyohograpesduringstorageperiodUUShu—yi,ZHANGJin,LIWei,CHENGuo—pin,XIELin_jun,LIHong—yan,YANGRen—gui,WENRen—de+
