    摘要:

    试验运用对比分析方法对西藏野生草莓果实品质进行了分析和定量评价。结果表明:西藏草莓、白果草莓果实色泽上差异明显;除单果重指标两者之间差异显著外(p<0.05,n=30),西藏草莓果实各表型指标值均低于白果草莓,不同种类果实间差异不显著(p>0.05,n=30);西藏草莓的可溶性固形物含量、可溶性糖、可滴定酸、VC含量等指标均高于白果草莓,且差异显著(p<0.05,n=5),但白果草莓的糖酸比高达5.67,显著高于西藏草莓。PPE模型分析结果表明:西藏草莓果实品质的函数投影值(1.846 9)远低于白果草莓(2.256 0)。西藏野生草莓虽然果实综合质量评价不高,但是其在风味草莓开发和系统生态价值上具有重要的开发和研究价值。

    Abstract:

    The fruit quality of were analyzed and evaluated quantitatively. The results showed there are obvious dif-ference between the two wild strawberry; The appearance indices of Tibetan strawberry are lower than that of whitestrawberry, and there no obvious differences between the treatments(p>0.05,n=30), but there are significant differ-ences between the treatments for themean fruit weight(p<0.05, n=30);The soluble solids content, the soluble sugar con-tent, the soluble acid and VC content of Tibetan strawberry are higher than that of white strawberry, and there are signif-icant differences between them(p<0.05,n=5), but sugar-acid ratio of white strawberry is 5.67, which is higher signifi-cantly than the Tibet strawberry. Phenotypic traits and quality traits of strawberry were analyzed quantitatively basedon the Projection pursuit model, projection values of Tibetan strawberrywas 1.846 9, which was lower than white straw-berry by 2.256 0. Through projection values of the two wild strawberry was limited, the wild strawberry have importantdevelopment and research value in the development of flavor strawberry and ecological value of ecosystem
