摘要: 为了探讨不同夏季修剪方法对巨玫瑰葡萄果实发育、品质及醇醛化合物含量的影响,将葡萄生长季的叶果比设置为20∶1,利用“三段式”修剪法,设置了“4+8+8”、“4+12+4”、“4+4+12”这3种修剪方法。自花后8周开始,每隔2周测定1次葡萄果实的质量、体积、可溶性固形物、原花青素、类黄酮、总酚含量以及己醛、2-己烯醛、己醇、2-己烯-1醇、橙花醇、里那醇等芳香化合物含量,并分析各指标间的相关性。结果表明:处理B(“4+12+4”)在果实发育、可溶性固形物含量以及1-己醇、橙花醇和里那醇的含量评价中要优于另外2个处理;“三段式”修剪法在新梢的中段留相对多的叶片,其果实品质要优于少留叶片;1-己醇、橙花醇和里那醇的含量与果实单粒质量、单粒体积、可溶性固形物、原花青素含量等葡萄成熟指标呈显著或极显著的正相关性。果实中橙花醇和里那醇的含量在果实成熟期前后增长的幅度最高。综上,夏季修剪方法会影响葡萄果实品质,采用“4+12+4”修剪方法后果实品质最佳。

Abstract: In order to explore the effects of different summer pruning methods on the fruit development, quality, alcohol and aldehyde compounds content of Jumeigui grape, the leaf-to-fruit ratio during the grape growing season was set to 20∶1, and the “three-stage” pruning method was used to be set 3 kinds of pruning methods which was “4+8+8”, “4+12+4” and “4+4+12”. The weight, volume, total soluble solid (TSS) content, procyanidine, flavonoids, total phenols, hexanal, 2-hexenal, hexanol, 2-hexene-1 alcohol, nerol, linalool contents, and other indicators of grape fruit were measured once every 2 weeks from 8 weeks after flowering. Correlation analysis was used to analyze the correlation between the indicators. The results showed that treatment B (“4+12+4”) was superior to the other two treatments in fruit development, TSS and the content of 1-hexanol, nerol and linalool. The fruit quality of the “three-stage” pruning method which left relatively more leaves in the middle of the new shoots was better than that of the less leaves. The content of 1-hexanol, nerol and linalool were significantly or highly significantly positively correlated with the grape ripening index which were single weight, single volume, soluble solids and proanthocyanidin content. The increasing strength of the content of nerol and linalool was the largest before and after fruit maturation period. In summary, the summer pruning method could affect the quality of the grape fruit, and the summer pruning method of treatment “4+12+4” was the best of all.
