摘　　要：为调整浙江省水蜜桃品种结构、延长供应期,并利于产地合理选择适宜品种,以浙江2个主栽品种黄肉桃锦绣黄桃和白肉桃奉化玉露为对照,对比研究4个日本引进品种清水白桃、秋白桃、新川中岛白桃和黄金桃以及2个国内品种秋玉露和徐蜜果实单果质量、果实大小、硬度、可溶性固形物含量、可滴定酸、还原性糖、有机酸、主要香气组分及其含量等生理指标,并结合品种生物学特性作出评价.结果表明:黄肉桃品种黄金桃风味品质优于对照品种锦绣黄桃,其可溶性固形物含量高,可滴定酸含量低,总香气组分含量高,但个别年份始花期可能会遭遇晚霜冻;3个日本白肉桃品种的果实大小、固酸比和贮藏性显著优于对照品种奉化玉露,特别是清水白桃香气最浓;2个国产品种徐蜜和秋玉露除果实大小和贮藏性优于奉化玉露外,其他风味品质无显著差异,而徐蜜质地不够细腻.In order to adjust to the peach structure,extend the supply period and choose suitable varieties for production area in Zhejiang Province,six middle and late maturity honey cultivars,including ＇Qingshuibaitao＇,＇Qiubaitao＇,＇Huangjintao＇ and ＇Xinchuanzhongdaobaitao＇ introduced from Japan,and other two Chinese cultivars ＇Qiuyulu＇ and ＇Xumi＇ were evaluated,based on their size,mass,firmness,total soluble solids,titratable acid,soluble sugar,organic acid and key aroma components.Two main varieties of yellow-fleshed ＇Jinxiuhuangtao＇ and white-fleshed ＇Fenghuayulu＇ were used as control.Meanwhile,the biological characteristics of each cultivar also were commented during the flowering and fruit development periods.The results showed that ＇Huangjintao＇ was better than ＇Jinxiuhuangtao＇ in flavor qualities,which had the higher soluble solids,total aroma content and lower titration acids,however,the former maybe experience late-frost at the flowering stage.Three white-fleshed cultivars from Japan were better in the fruit mass,total soluble solids / acid ratio and storage character.Especially,the fragrance of ＇Qingshuibaitao＇ was the strongest.Two domestic cultivars ＇Xumi＇ and ＇Qiuyulu＇ had obvious advantages in the fruit mass and storage characteristic compared with the cultivar ＇Fenghuayulu＇,and other flavor qualities had no significant differences.However,＇Xumi＇ was more coarse in texture.
