摘要
[目的]了解南宁地区阳光玫瑰葡萄夏果和不同修剪时期冬果的品质差异。[方法]以阳光玫瑰葡萄2月5日修剪的夏果、8月20日和8月29日修剪的冬果为试材(其中8月29日修剪的树体转色期后进行保温处理),分别测定果实的穗重、粒重、可溶性固形物、总糖、可滴定酸、固酸比以及Vc等果实品质指标。分析夏果和不同修剪时期冬果的果实品质差异。[结果]在一年两收栽培模式下的阳光玫瑰葡萄夏果品质优于冬果,夏果可溶性固形物、总糖及Vc含量均高于冬果;8月29日修剪保温的阳光玫瑰冬果Vc及固酸比均高于8月20日修剪不保温的冬果,且其可滴定酸含量更低。[结论]该研究为葡萄一年两收生产中果实品质的提高提供了理论依据。
[Objective] To study the quality differences between summer fruits and winter fruits of Shine Muscat in Nanning Area at different pruning periods.[Method] The summer fruits of Shine Muscat pruned on February 5 th and winter fruits pruned on August 20 th and August 29 th were taken as the test materials. The panicle weight,single grain weight,soluble solids,total sugar,titratable acid,ratio of acid to solid,and Vc were determined. Quality differences between the summer and winter fruits at different pruning periods were analyzed.[Result]Under the mode of double harvest every year,the quality of the summer fruits were superior than that of winter fruits. The soluble solids,total sugar and Vc content of summer fruits were higher than those of winter fruits. The Vc and solid acid ratio of Shine Muscat pruned on August 29 th were higher than those on August 20 th,and the titratable acid content was lower.[Conclusion]This research provided theoretical foundation for the enhancement of fruit quality under the mode of double harvest every year.
