[Methods]With Muscat Hamburg grape from different producing areas as an experimental material,procyanidine content was determined by n-butanol-hydrochloric acid colorimetry. [Results] The procyanidins contents in different parts of the same variety ranked as grape seed > grape skin > grape flesh. The procyanidins contents in grapes from different producing areas were in order of Changli County,Hebei Province > Dazeshan Town,Shandong Province > Hangu District,Tianjin City.[Conclusions]The procyanidins contents in Muscat Hamburg grapes from different producing areas differ to a certain degree.展开更多

The results showed that the soil p H was lower,and the soil K,Ca and total salt( 0. 445%) contents were higher in the vineyard of Ninghe District than those in the vineyard of Hangu District. There were no significant differences in the soil Mg,Fe and Na contents between the vineyards in the two regions. The soil of the vineyard in Ninghe District is medium loam,and that in Hangu District is heavy loam. In short,all the soil indicators of the vineyard in Ninghe District were better than those in Hangu District except the indicator of soil salt content. The soluble sugar and soluble protein contents of one-year-old vine branches differed significantly between the two regions.展开更多
以玫瑰香(Vitis vinifera L. cv. Muscat Hamburg)葡萄为试材,研究果实纵横径,始熟期前后pH值、可溶性糖、总酸和脱落酸含量的变化。结果表明,玫瑰香葡萄果实纵横径变化趋势基本一致,分第一个快速生长期、缓慢生长期、第二个快速生长期...以玫瑰香(Vitis vinifera L. cv. Muscat Hamburg)葡萄为试材,研究果实纵横径,始熟期前后pH值、可溶性糖、总酸和脱落酸含量的变化。结果表明,玫瑰香葡萄果实纵横径变化趋势基本一致,分第一个快速生长期、缓慢生长期、第二个快速生长期三个时期,果实内可溶性糖主要为葡萄糖和果糖,蔗糖含量很少。可溶性糖含量在始熟期开始快速上升,三种糖变化趋势基本一致。葡萄糖、果糖和蔗糖始熟期前平均日增量分别为0.29,0.23,0.01 mg/g,始熟期后三者平均日增量分别为1.35,1.67,0.12 mg/g。始熟期前果实内葡萄糖∶果糖为12∶1,始熟期后葡萄糖和果糖含量开始快速升高,果糖升高速率高于葡萄糖,到花后77 d,二者差距逐渐缩至葡萄糖∶果糖为1∶1。pH值在始熟期开始快速升高,总酸含量和pH值呈吻合相反变化趋势。脱落酸含量伴随始熟的发生而迅速增加,果实成熟阶段有一个高峰,完熟前下降。总之,随着花后56 d葡萄果实成熟的启动,可溶性糖含量(主要葡萄糖和果糖)、pH值和ABA水平开始快速上升。葡萄果实成熟的启动依赖于ABA峰出现,而果实完熟过程不依赖于ABA的积累。葡萄果实始熟期前后可溶性糖含量、pH值和ABA水平之间平行关系调控的生理机制,即ABA持续积累的生理机制是今后研究的重要内容。展开更多
