摘　　要：目的:对不同产地杭菊各栽培类型主要植物学性状进行比较,以期为杭菊规范化引种栽培提供依据。方法:测定不同产地杭菊植株、叶片及头状花序特征进行分析比较。结果:不同产地杭菊植株高度范围为60.87～99.47 cm,分枝数为2.76～5.20;叶长为4.90～8.40 cm;叶宽为3.25～5.38 cm;叶片长宽比为1.35～1.83;叶裂数为1.92～3.08。头状花序数为21.92～53.12;直径为3.41～5.48 cm;舌状花层数为3.28～7.16;舌状花瓣数为55.32～114.60;舌状花瓣长为1.58～2.37cm;瓣宽为0.50～0.69 cm;瓣长宽比为2.90～3.99;管状花直径为1.10～1.58 cm。结论:不同产地杭菊植物学性状差异显著,随着引种栽培环境的改变,杭菊植物学性状发生了一定的改变。Objective： To compare botanical characteristics of cultivated Chrysanthemum morifolium cv. ＇Hangju＇ of different origins in order to provide the basis for introduction and cultivation of Ch. morifolium cv. ＇Hangju＇ . Method： The characteristics of plants, leaves and capitulum of Ch. morifolium cv. ＇Hangju＇ were measured, and the obtained data were analyzed and compared. Re- sult： The range of plant height was 60.87-99.47 cm, number of branches 2.76-5.20, leave length 4.90-8.40 cm, leave width 3.25- 5.38 cm, aspect ratio of leave 1.35-1.83, number of leave split 1.92-3.08. Numbers of capitulum were 21.92-53.12, diameter of ca- pitulum 3.41-5.48 cm, lays of ray florets 3.28-7.16, number of ray florets 55.32-114.60, ray florets length 1.58-2.37 cm, ray florets width 0.50-0.69 cm, aspect ratio of ray florets 2.90-3.99, diameter of tubular fower 1.10-1.58 cm. Conclusion： The botanical characteristics of cultivated Ch. morifolium cv. ＇Hangju＇ were distinguished from different origins. With the cultivation environment change, the botanical characteristics of the cuhivars are changed.
