以贵州本地8个李资源的成熟叶片及果实为试材,从叶形特征、果实外部形态特征及果实内在品质性状等不同方面对其进行了调查研究。结果显示:①贵州地方李的叶形特征中以叶片形状的变异范围最为广泛,有卵圆形、椭圆形、披针形、倒披针形等,其次为叶尖形状、叶基部形状和叶柄腺形状;②果实形态特征中以果皮和果肉颜色的变异范围最为广泛,其次为果实成熟期、果实形状、梗洼及缝合线的深浅以及果顶形状;③贵州地方李的单果质量、果实横纵径及果形指数、核横纵径等性状的平均变异系数均在9%以上,其中单果重的变异幅度为18.3~38.9g,变异系数最大,达24.92%;④果实内在品质性状方面以可溶性固形物的变异系数最低,为8.50%,可溶性总糖的变异系数最高,为13.44%。
An experiment was conducted to investigate leaves, fruits, and fruit internal traits of 8 local plum varieties from Guizhou Province, China. The results showed that: ① the shapes of leaves had the most widely range of variation, for example orbicular-ovate, ellipse shape, lanceolate, and oblarcoelate. The shapes of leaf apex, leaf base, and nectary had smaller range of variation than the shapes of leaves; ② the color of flesh and pericarp had the most wide range of variation, followed by maturity, fruit shape, depth of suture line, and blossomend shape; ③ the average coefficient of variation of simple fruit weight, transverse length, vertical length and shape index were over 9%. The range of variation for simple fruit weight was 18.3 to 38.9 g with the coefficient of variation of 24.92%; ④ the variation coefficient fruit internal quality was 8.5%, which was the lowest among soluble solid contents, and the coefficient of variation of total soluble sugar content was as high as 13.44%.
