摘要:
 以695个野生刺葡萄（Vitis davidii）种质为材料，测量9个叶片度量性状，通过Galet的数值分析法将叶片性状数量化并对野生刺葡萄材料进行分类。结果表明，野生刺葡萄的成熟叶型具有丰富多样性，叶片主脉长为67~272 mm，其他叶脉长度和夹角也存在不同程度的变异，叶面积变化范围为43.85~573.12 cm2。野生刺葡萄叶型变异主成分为叶脉长度和叶面积的变化（占总变异的58.81%），而夹角变化占总变异的15.40%，2个主成分的贡献率累积为74.21%。聚类分析结果显示刺葡萄材料间的欧式平方距离从1到25变化，距离系数为1的材料用A系列表示。在距离系数为5时，刺葡萄材料被分成45类。当距离系数为25时，野生刺葡萄材料被分成2大类，第1类由111个A系列和138个刺葡萄材料组成，而第2大类仅由编号为565和646的2个材料组成。
Abstract:
 Vitis davidii is one of the wild grape species in China,and it is widely distributed in the area of southern Qinling Mountains.It is resistant to Botrytis rot,Coniothyrium diplodiella,Glomerella cingulata,and anthracnose with high application values.Six hundred and ninety five accessions of V.davidii were collected and used as materials in this study.Nine metric leaf characters were measured.The leaf traits were characterized quantitatively by using the Galet numerical analysis method,and the wild V.davidii materials were classified.The mature leaf shape demonstrated rich diversity.The length of the main leaf vein was from 67 to 272 mm,other vein lengths and angles also had different degrees of variation.The leaf area ranged from 43.85 to 573.12 cm2.The principal components of the variation were leaf length and leaf area (accounting for 58.81% of the total variance).The variance of angle accounted for 15.40% of the total variation.The contribution of the two principal components was 74.21%.Cluster analysis showed that the Euclidean square distance among the V.davidii materials changed from 1 to 25.The material with a distance coefficient of 1 was expressed in A series.When the coefficient was 5,the materials were divided into 45 types.When the distance coefficient was 25,the materials were divided into 2 categories.The first category was made up of 111 A series with 138 materials,and the second major category was consisted of only two materials:No.565 and No.646.
