不同花序修剪长度对阳光玫瑰葡萄商品性状的影响

Effects of Inflorescence Length on the Commercial Properties of Shine Muscat Grape

[目的]不同花序修整长度对阳光玫瑰葡萄商品性状的影响。[方法]在花后7~14 d分别对花序保留不同长度的修剪,保留花序的长度分别为5.0、6.0、7.0、8.0和9.0 cm。果实成熟后,分析不同果穗长度对阳光玫瑰葡萄果粒和果穗的重量及长度、果实可溶性固形物含量的影响。[结果]当花序长度为9.0 cm时成熟后的果穗长度最长,约14.5 cm,当花序长度为5 cm时成熟后的果穗长度最短,约10.0 cm,各处理成熟果穗的长度差异显著;当花序长度为7.0 cm时,成熟后果实单粒重为9.2 g,果实可溶性固形物含量较高,为20.5%。[结论]阳光玫瑰葡萄在露地栽培条件下,适当进行花序修剪可以提高果实的外观品质,并增加单粒重和可溶性固形物含量。

[Objective]To explore effects of inflorescence length on the commodity properties on Shine Muscat grape.[Method]The inflorescences were pruned for the different lengths(5,6,7,8 and 9 cm).Then the size,weight,and the soluble solid content of berry and the length of clusters of Shine Muscat grape were analyzed.[Result]The length of grape cluster was 14.5 cm when the length of inflorescence was pruned for 9 cm.The length of grape cluster was 10 cm with 5 cm inflorescence.The single berry height was the highest with 10.0 g when the inflorescence length was pruned for 7 cm.The highest soluble solid content(SSC)was obtained with 7-8 cm,and SSC was 20.5%.[Conclusion]Under the conditions of open field cultivation,proper inflorescence pruning can improve the appearance quality of the fruit,and increase the single grain weight and soluble solid content.
