盐碱地3个葡萄新品种果实品质比较

Comparison of fruit quality of three new grape varieties in saline-alkali land

为比较不同葡萄品种在盐碱土壤果实品质的差异,以‘阳光玫瑰’‘蓝天无核’‘大红指2号’3个品种为试材,测定了单果重、果形指数、果实硬度、可溶性糖、可滴定酸、可溶性固形物、含水量以及Vc含量等指标,并通过隶属函数的计算进行了果实品质的综合分析。结果显示:‘大红指2号’在单果重、果型指数和硬度都最高,‘阳光玫瑰’在Vc含量、可滴定酸、可溶性糖、可溶性固形物以及含水量均优于其他2个品种。综合分析结果为:‘大红指2号’>‘阳光玫瑰’>‘蓝天无核’。

In order to compare the differences of fruit quality among different grape varieties in saline-alkali soil,the single fruit weight,fruit shape index,fruit hardness,soluble sugar,titratable acid,soluble solids,water content and Vc content were measured with three varieties,Sunshine Rose,Blue Sky Seedless and Red finger No.2,respectively.The comprehensive analysis of fruit quality was carried out through the calculation of membership function.The results showed that No.2 had the highest fruit weight,fruit shape index and hardness,and the contents of Vc,titratable acid,soluble sugar,soluble solids and water content of sunshine rose were superior to those of the other two varieties.The result of comprehensive analysis is:Red finger No.2>Sunshine Rose>Blue Sky Seedless.
