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 the main botanical characters of each species of Hang-chrysanthemum in different habitats, in order to provide the basis for the standard introduction and cultivation of Chrysanthemum indicum. Methods: The characteristics of plants, leaves and flower heads of Chrysanthemum indicum from different areas were analyzed and compared. Results: The plant height of Hang chrysanthemum in different habitats ranged from 60.87 to 99.47 cm, the number of branches was from 2.76 to 5.20, the leaf length was from 4.90 to 8.40 cm, the leaf width was from 3.25 to 5.38 cm, and the leaf aspect ratio was from 1.35 to 1.83. The number of 1.92 ~ 3.08. The number of flower heads is from 21.92 to 53.12 and the diameter is from 3.41 to 5.48 cm. The number of tongue-shaped flowers is from 3.28 to 7.16. The number of tongue-shaped flowers is from 55.32 to 114.60. The length of tongue-like flowers is from 1.58 to 2.37 cm. 0.69 cm; the aspect ratio of the petals was 2.90-3.9; the diameter of the tubular flowers was 1.10-1.58 cm. Conclusion: There are significant differences in the botanical characters of Hang chrysanthemum in different habitats. With the introduction of the cultivation environment, Chrysanthemum chrysanthemum has some changes in its botanical characters.
