| 摘要: |
| 【目的】探讨山西临汾地区‘西拉’（Syrah）葡萄转色期果穗不同疏除方式对果实酚类物质含量的影响，为酿造优质西拉干红葡萄酒奠定基础。【方法】葡萄转色前保留全部果穗，转色期设置不疏除果穗（C1）、疏除25%果穗（C2）和疏除50%果穗（C3）3种果穗疏除处理，在葡萄成熟过程监控不同处理果实的成熟度，采收后测定果实总酚、单宁、总花色苷、单体花色苷和单体酚类物质含量，分析果穗疏除处理对果实酚类物质的影响。【结果】与C1相比，C2、C3处理提高了葡萄还原糖含量，降低了总酸含量；采收期各处理葡萄果实的总酚含量存在显著差异，总酚含量排序为C1（39.61 mg/g）

| Abstract: |
| 【Objective】This study investigated the effect of different cluster thinning levels during veraison on phenolic contents of grape in Linfen,Shanxi to provide basis for high quality dry red winemaking.【Method】All the clusters were reserved until being thinned during veraison at three levels of C1 (0%),C2 (25%) and C3 (50%).Berry maturity was monitored during grape ripening and the contents of total phenol,tannin,total anthocyanin,monomer anthocyanin and monomer phenolic were measured after harvest.【Result】 Compared with C1,C2 and C3 treatments improved the reducing sugar while decreased the total acid content.The total phenol contents were significantly different among treatments with the order of C1(39.61 mg/g)Vitis vinifera L.cv.Syrah effectively,while tannin content was decreased by 50% thinning. |
