关于紫菜生活史的研究,我们根据在自然界的观察和在实验室里的实验,证明了,从丝状体阶段转回叶状体阶段——即普通习见的紫菜藻体,是通过壳孢子的方式而实现的。在紫菜的生长地区,每年秋季有大量的紫菜孢子突然出现于海面;它们就是紫菜养殖工作者在插篊或处理紫菜磹以后所盼望的紫菜“种子”。多年以来,这些孢子的来源,在科学上是一个谜;养殖工作者因为不知道它们的来源而无法进行紫菜的留种、播种工作,每年所需要的紫菜“种子”只能听凭着自然的摆布。确定了紫菜是从丝状 On the life history of seaweed research, we observed in nature and experiments in the laboratory, we prove that from the filament phase to the frond phase - that common habit of seaweed algae, is through the conchospores Way and achieve. In the area where the seaweed grows, a large number of seaweed spores suddenly appear on the sea every fall; they are the seaweed “seeds” that seaweed growers look forward to after inserting or handling seaweed. The source of these spores has for many years been a scientific mystery; for breed workers who can not grow or seagrass the seaweed because they do not know their origins, the seaweed “seeds” needed each year only depend on nature The mercy It is determined that the seaweed is from the filamentous
