硼对高等植物生长的影响,已有不少的研究。有人认为它是植物生长所必需的元素,有人不同意这个意见,硼对海藻的效应,研究的不多。McBride等的观察指出,硼对小球藻的生长没有什么影响。Lewin的实验表明,硼对硅藻的生长是必需的。Nasr等的观察指出,硼对石(艹尊)和Dictyota的生殖有刺激作用。 本实验在于观察硼对海带雌配子体生长发育的效应。1973年和1976年,我们曾做了一些探索性实验,1979—1980年又重复了实验,这里仅汇报一部分实验的结果。
Boron on the growth of higher plants, there have been many studies. Some people think that it is an essential element of plant growth, some people do not agree with this opinion, the effect of boron on seaweed, less research. Observations by McBride et al. Indicate that boron has no effect on the growth of Chlorella. Lewin’s experiments show that boron is necessary for the growth of diatoms. Nasr et al.’s observations point out that boron stimulates the reproduction of stone and Dictyota. The experiment is to observe the effect of boron on the growth and development of female gametophyte. We did some exploratory experiments in 1973 and 1976, and we repeated the experiments in 1979-1980, where we only report the results of some experiments.
