Abstract
|
|
|
A comparative study of karyotype of Cnidium officinale Complex growing in Korea was carried out.
The study shoes following:The somatic chromosome number of Ill Chun Gung was found to be 2N=22and that of Toh Chun Gung 2N=33,that of Toh Chun Gung(Ullung Island)2N=44 The karyotype of species Ill Chun Gung were as follows:the 22 chromosome were in 11 pairs,which could be classified into the 5 pairs of Submedium chromosome,4 pairs of Medium ones and 2 pairs of Subterminal of which one had satellite.
The karyotype of Toh Chun Gung were as follows:
the 33 chromosome were in 16 pairs one chromosome.8 pairs of Submedium chromosome,6 pairs of Medium ones and 2 pairs of Subterminal and one terminal chromosome.
The karyotype of Toh Chun Gung (Ullung Island) were as follows:the 44 chromosome were in 22 pairs,13 pairs of Submedium,8 pairs Medium and 1 pairs of Subtrminal of which had satellite.
In size of stoma and cell,Toh Chun Gung is strickingly larger than,Ill Chun Gung.
The pollen ferility of Toh Chun Gung was zero,Ill Chun Gung was 1-3%.
In the clone of Cnidium officinlae Makino growing in Korea,the karyotype was the orginal one,while,that of Toh Chun Gung presumably derives from the orginal karyotype.Toh Chun Gung is verified to be the polyploid in genus Cnidium.
Ill Chun Ghun was found a diploid,and Toh Chun Gung was found a triploid,Toh Chun Gung(Ullung Island),was found a tetraploid.
