Cytotaxonomic Studies on the Umbelliferae Plants -Cytological Study and Fertility of Pollen in Umbelliferae-

산형과식물의 세포분류학적 연구 -Angelica속 및 Cnidium 속식물의 염색체수와 화분 결실도-

A comparative study on Angelica and Cnidium, the two genera of Umbelliferae growing in Korea, was carried about the cytology and fertility of pollen. The somatic chromosome number of Umbelliferae was found almost to be 2N=22. Both species of Kang-whal and Chun-gung were found to be in polyploid with different chromosome numbers each other. The pollen fertility among the species of Angelica was high, but Toh-chun-gung was zero percent. The species of Angelica have been generated with pollen fertility, but species of Cnidium with only root or rootlet.
