| 摘 要： | 为了更好地对怒江杧果种质资源进行评价研究,丰富我国数量化、规范化的杧果种质资源描述系统,对243份怒江流域杧果种质资源的主要数量性状(叶长、叶宽、叶柄长、果质量、果长、果宽、果厚、可食率和可溶性固形物等指标)进行分析研究。结果表明,以上9个性状均存在13%以上的变异系数,并且对这些数量性状进行K-S检验,对符合正态分布的数量性状统一用(X-1.2818S)、(X-0.5246S)、(X+0.5246S)和(X+1.2818S)4个点分为5级,使1～5级的出现频率分别为10%、20%、40%和10%,χ2分布性状近似的按正态分布性状处理。该研究为我国杧果种质资源描述规范和数据标准化的建立提供参考。

| Abstract: | Nine quantitative characteristics including length of leaf,width of leaf,length of stalk,average fruit weight,length of fruit,width of fruit,thick of fruit,edible rate of fruit,soluble solids content of 243 mango cultivars were evaluated. The results showed that all the quantitative characteristics and their coefficients of variation were above 13%. These main quantitative characteristics were analyzed by K-S test. The values of normally distributed characteristics could be divided into 5 grades by dividing... |
