摘要
[目的]分析海拔和行向对酿酒葡萄果实生长发育及品质的影响,为云南香格里拉高原葡萄产区葡萄的栽培管理提供理论指导。[方法]以云南香格里拉地区酿酒葡萄赤霞珠为试材,研究低、中、高3个海拔高度(2 047,2 208和2 387 m)和2个葡萄种植行向(东西行向和南北行向)对果实生长发育指标(单粒质量、果粒横纵径)、基本品质指标(可溶性固形物、还原糖和可滴定酸含量)及酚类物质含量(总花色苷、单体花色苷和非花色苷酚类物质)的影响。[结果](1)在3个海拔高度的葡萄园中,东西行向葡萄果实横纵径和单粒质量均高于南北行向,且随着海拔的升高表现出逐渐增大的趋势。(2)花后18周,南北行向果实可溶性固形物含量和还原糖含量均高于东西行向;且高海拔葡萄园行向间差异显著,南北行向可溶性固形物含量和还原糖含量较东西行向分别提高了17.76%和15.79%;可滴定酸含量则表现为东西行向高于南北行向,但行向间差异不显著。(3)花后18周,总花色苷含量和非酰化花色苷总量在低海拔葡萄园表现为南北行向高于东西行向,中高海拔葡萄园则以东西行向高于南北行向。(4)非花色苷酚类物质总量以中海拔葡萄园最高,且南北行向显著高于东西行向,提高了62.70%;黄烷醇类物质含量则是东西行向显著高于南北行向,提高了近2倍。[结论]在云南香格里拉地区,海拔和行向均对葡萄果实生长发育及品质存在影响,且以低海拔南北行向、中高海拔东西行向更有利于果实品质的提高。
[Objective] The influence of altitude and row orientation on growth and quality of wine grape berries was analyzed to provide guidance for cultivation and management of grapes in grape production areas of Shangri-la Plateau, Yunnan.[Method] Using wine grape Cabernet Sauvignon in the Shangri-la region as test material, the effects of three altitudes(2 047 m, 2 208 m and 2 387 m) and two row orientations(EW orientation and NS orientation) on berry growth and development indexes(single grain weight and transverse and longitudinal diameter),basic quality indicators(soluble solid content, reducing sugar content and titratable acid content) and phenolic contents(total anthocyanin, monomer anthocyanin, non-anthocyanin phenolic) were studied.[Result](1) In vineyards at three elevations, single grain weight and transverse and longitudinal diameters of the EW orientation were higher than those of the NS orientation with a gradually increasing trend with the increase of elevation.(2) Contents of soluble solids and reducing sugar in the NS orientation were higher than those in the EW orientation at 18 weeks after flowering, and there were significant differences between row orientations at high altitudes(2 387 m).Compared with the EW orientation, it was increased by 17.76% and 15.79%,respectively.The titratable acid content was higher in the EW orientation than that in the NS orientation, without significant differences.(3) Both total anthocyanin content and non-acylated anthocyanin showed that the NS orientation of vineyard at low altitude(2 047 m) was higher than the EW orientation, and the EW orientation at medium and high altitudes was higher than the NS orientation at 18 weeks after flowering.(4) The total content of non-anthocyanin phenols was the highest in vineyards at the middle altitude(2 208 m), and the NS orientation was significantly higher than that of EW orientation(increased by 62.70%).The content of flavanols in the EW orientation was significantly higher than that in the NS orientation(2 times).[Conclusion]
