药用菊花不同栽培类型植物学形态比较

目的：通过对中国药用白菊花不同栽培类型的植物学性状观测和比较，以期为药用白菊花遗传多样性的研究及优良品种的选育提供依据。方法：采用随机区组田间试验设计，分别对药用菊花的叶片形状、头状花序中舌状花和管状花的颜色以及数目等主要形态特征进行测定；结合方差统计分析方法，对药用菊花不同栽培类型的主要植物学性状进行比较分析。结果与结论：药用菊花不同栽培类型植物学性状存在一定的差异，叶片锯齿数、叶柄长度以及叶裂数三者为相对独立的性状，是不同药用菊花类型叶片形态的重要特征。根据植物学形态差异药用菊花不同栽培类型可划分为7个类群。

Comparative study on botanical morphologic character of different cultivated types medicinal Chrysanthemum morifolium

Objective: Botanical character of different cultivated types medicinal Chrysanthemum morifolium were observed and compared, which can offer reference for its genetic diversity research and breeding. Method: Based on the random blocks field experiments design, the main character of leaf and capitulum of medicinal C. morifolium were observed, it was studied on that the botanical character of different cultivated types medicinal C. morifolium in China were comparatively study with statistical means. Result and conclusion: There are some different of botanical character among different cultivated types medicinal C. morifolium in China, which can be divided into 7 colonies according as its diversity of the botanical and morphological character. The sawtooth number of lamina, leafstalk length and leaf division number are the important laminae morphologic character of different types medicinal C. morifolium, which are relative independent characters.
