| Research Abstract |
Camellia japonica L.is widely distributed from Southeast Asia to Japan. More than ten thousand cultivars have been bred all over the world. In Europe, United States of America and Australia, the Camellia garden cultures have been very popular as the ornamental trees and shrubs. The new cultivars that have more cold resistance and more heat resistance are hoped. This study was carried out to produce the auto-tetraploid cultivars that have some merits, for example, the giantness of leaves or flowers, the cold resistance and the heat resistance.
The auto-tetraploid individuals have not been observed in Camellia genus. We examined the seedlings obtained from some auto-triploid cultivars. The "Kumagae" which belongs to Higo tubaki group was reported to be auto-triploid cultivars. The survey of the numbers of the chromosomes and the stomata was carried out with the light microscope which was bought by Grant-in-Aid for Scientific Research. The large stomata were observed in the seedling No.12 obtained from "Kumagae". The number of the stomata per one microscopic field at magnification 10*20 of the seedling No.12 is so small that the seedling is probably suggested to be tetra-ploid. For the future study, some other allo-polyproid cultivars were collected this year.
