摘要
为揭示地形条件对酿酒葡萄果实品质的影响,对河北省昌黎县不同地形条件(平地和坡地)下2种酿酒葡萄[赤霞珠(Cabernet Sauvignon)和西拉(Syrah)]的果实成熟度和品质进行比较。结果表明,①赤霞珠和西拉在成熟过程中,其果实总酸含量随还原糖含量的不断增加而下降,而果实糖酸比一直上升;2个品种的还原糖含量均表现为坡地>平地。②赤霞珠果实的总酚、单宁、总花色苷含量和糖酸比均表现为平地>坡地,总酸含量则表现为坡地优于平地;而西拉果实的单宁、总花色苷含量及糖酸比均表现为坡地>平地,总酸和总酚含量则为平地>坡地。③平地与坡地条件下两酿酒葡萄品种的单宁含量呈极显著差异,而总花色素仅赤霞珠表现为显著性差异。这表明坡地条件下赤霞珠和西拉酿酒葡萄果实品质优于平地。
The research was conducted in Changli county in 2010.Two wine grape varieties（Cabernet Sauvignon,Syrah） grown in different terrains were chosen to compare grape maturity and quality.Results showed that：（i） Total acid content was both decreased with the increment of reducing sugar content and sugar acid ratio of Cabernet Sauvignon and Syrah.Simultaneously,reducing sugar content was indicated in the same tendency： hillside land vineyardflat land vineyard;（ii） Total phenol,tannin content,total anthocyanin content and sugar acid ratio on flat land vineyard were higher than that on hillside land vineyard.While total acid content was opposite;but for Syrah,sugar acid ratio,tannin content,total anthocyanin content were as follows ： hillside vineyardflat land vineyard.By contrast,total acid content and total phenol of flat land vineyard were higher than that of hillside land vineyard.（iii）There was a very significant difference of two varieties on Tannin content between flat land vineyard and hillside land vineyard,only total anthocyanin content of Cabernet Sauvignon reached a significant level on different terrain.Overall,the quality of wine grape on hillside land vineyard was better than that on flatland vineyard.
