Abstract
|
|
|
A comparative study of the gros morphology and cytology of Toh Chun Gung and Ⅲ Chum Gung, the two taxa of Cnidium officinale MAKINO growing in Korea was carried out.
The taxon of Toh Chun Gung is taller that of Ⅲ Chun gung and shows greater growth rate than that of the latter.
The root of the former is irregular in shape, having large branches and that of the latter is taro-like in shape and has nodules.
The pollens of oth taxa are subspheroidal or ellipsoidal, but the pollens of Toh Chun gung are sometimes subtriangular.
The somatic chromosome number of Toh Chun Gung was found to be 2N=33 and that of Ⅲ Chun Gung 2N=22.
Toh Chun Gung is considered as a triploid which may have originated from between Ⅲ Chun Gung, a diploid, and a tetraploid of the latter or other taxon of the genus Cnidium.
The pollen fertility of Toh Chun Gung was found to be very low or almost zero.
