摘要：

以3年生‘贝达’砧木设施栽培‘京蜜’葡萄为试材,研究直立、V形和水平3种叶幕形处理下葡萄叶幕微环境、叶片质量及果实品质的差异.结果表明: 直立叶幕的总孔隙度和开度显著高于V形叶幕和水平叶幕,叶面积指数、光能截获率和叶幕昼夜温差均显著低于V形叶幕和水平叶幕,后两者间无显著差异.V形叶幕葡萄叶片的栅栏组织厚度显著大于直立叶幕,水平叶幕居中,叶绿素和类胡萝卜素含量显著高于直立叶幕和水平叶幕,后两者间无显著差异.果实品质以V形叶幕最佳,水平叶幕其次,直立叶幕最差.通过GC-MS分析发现,V形叶幕挥发性香气化合物种类最多,为29种,直立叶幕与水平形叶幕分别为17和16种.V形叶幕中‘京蜜’葡萄的特征香气组分除乙醇、反式-2-己烯-1-醇、仲辛酮和甲酸己酯含量较低外,其余含量均较高.芳樟醇(里那醇)含量在直立叶幕和V形叶幕中显著高于水平叶幕,橙花醇含量在V形叶幕中显著高于直立叶幕和水平叶幕,叶醇含量在V形叶幕和水平叶幕中显著高于直立叶幕,香茅醇仅在V形叶幕中检出.V形叶幕设施栽培葡萄的果实香气更浓,更能体现其品种特性.

Abstract: The effects of three canopy shapes, i.e., vertical canopy, V shaped canopy and horizontal canopy, on canopy microenvironment, quality of leaves and fruits were studied in the 3-year-old grape ‘Jingmi’ grafted on ‘Beta’ in greenhouse. The results showed that gap fraction and openness of vertical canopy were significantly higher than that of Vshaped canopy and horizontal canopy, and leaf area index, light interception rate and canopy temperature difference between day and night were significantly lower than those of V shaped canopy and horizontal canopy. There was no significant difference between the latter two treatments. The palisade thickness of V-shaped canopy was significantly greater than that of vertical canopy, and horizontal canopy was in the middle. The chlorophyll and carotenoid contents of V shaped canopy were significantly higher than those of vertical canopy and horizontal canopy, and those in the latter two treatments had no significant difference. The fruit quality of V shaped canopy was the best, and that of horizontal canopy was the worst. The results of GC-MS analysis showed that 29 types of volatile aroma compounds were detected in V-shaped canopy, but just 17 and 16 in vertical canopy and horizontal canopy, respectively. In V shaped canopy, the characteristic aroma in grape ‘Jingmi’ was higher, except ethanol, trans-2-hexene-1-alcohol, 2-octyl ketone and formic acid ester. The linalool content in vertical canopy and V shaped canopy was higher than that in horizontal canopy. The nerol content in Vshaped canopy was higher than that in vertical canopy and horizontal canopy, and the leaf alcohol content in Vshaped canopy and horizontal canopy was higher than that in vertical canopy. The citronellol was detected only in Vshaped canopy. In greenhouse, the fruit aroma of Vshaped canopy grape was stronger, and well reflected the variety characteristics.
