| 摘 要： | 若干海藻工作者已在海带、厚叶翅藻等褐藻中观察到孤雌生殖的现象1]3]4]。我们于1973年开始了海带单倍体遗传育种的实验后,从1974年起我们就裙带菜(Undaria pinnatifida Sur.)进行了相似的试验。这里着重就裙带菜的孤雌生殖及其后代所表现的细胞遗传学特点,进行一些观察。大部分材料是1977年的实验结果。关于裙带菜配子体的无性生殖系将另作总结。

| Abstract: | A series of genetic experiments on parthenogenesis has been carried out in Undaria pinnatifita since 197.The nature of this investigation is quite similar to that done in Laminaria japonica,and similar results have been obtained.The.originai materials used to collect the zoospores were taken from the sea shore and the mature sporophytes were believed to be highly heterozygous in heredity.The methods applied were as follows:Isolation of single,individual female gametophytes was carefully made,one slide containing only one gametophyte.Cultivation of the gametophytes was mainly at 15-20℃.Light intensity was about 1500 luxes.Illumination with white fluorescent light was 10 hours a day.The culture medium was made by boiled sea water with the addition of suitable concentration of mineral salts such as P-0.4ppm and N-4ppm. |
