Abstract
|
|
|
Lilium Miquelianum Makino is a species which originated in Korea.
The Karyotype of the species was examined in materials collected at Mts. Kaya, Kasan, Chejung, and Kaji.
The results are as follows:
1) The somatic chromosome number was found to be 2n=24.
2) The karyotype is described as:
K=2A^m+2B^sm+2C??+2D??+2E^st+2F^st+2G^st+2H^st+2I^st+2J??+2K^st+2L^st_2D??
m: metacentric, sm: submetacentric st: subtelocentric, s: secondary constriction
3) A single subcentric supernumerary B-chromosome was found in some bulbs from Mt. Kasan.
4) The shape of the supernumerary B-chromosome was similar to that of the E chromosome which had separated at its secondary constriction and lost its lower chromosome fragment.
5) From three to eight nucleoli of varying sizes were found in the telophase or interphase nucleus of root tip cells. The maximum number of eight nucleoli corrseponds to the number of chromosomes that have a secondary constriction.
