摘要
本文根据Galet的葡萄叶形结构测定原理,用多元判别和计算机图形分析,对我国南方主要栽培的4个鲜食葡萄品种(巨峰、藤稔、美人指、希姆劳特)的叶片形态参数进行数值化鉴别。结果表明,测量的7个叶形结构参数在区分4个鲜食葡萄品种上有不同的作用,同时根据叶片测量数据,绘制判别分布图和叶形结构参数均值脸谱图形,这有利于更好的对葡萄品种进行鉴别。
Galet’s ampelographic method, Multiple discriminate analysis and Computer graphics were adopted to identify and describe 4 table grape cultivars widely cultivated in the South of China, i.e. Kyoho, Fujiminori, Manicure Finger and Himrod. The results revealed that all the 7 foliar morphological parameters contributed variously to the cultivar identification,The four cultivars were finally characterized with the help of drawing the chart of scatterplot of canonical scores and chernoff face of foliar structural means.
