条斑紫菜(Porphyra yezoensis Ueda)是我国北方紫菜种类中的主要人工养殖对象。要开展这种紫菜的人工养殖,首先必须培养好其丝状体,以便适时得到大量壳孢子,满足人工采苗的要求。因此,了解丝状体的生长发育同环境条件的关系,对培养好丝状体是非常必要的。 温度是影响丝状体生长发育的一个重要环境因子。关于这方面的研究工作,过去已有 Porphyra yezoensis Ueda is the main cultured species of laver species in northern China. To carry out artificial breeding of this seaweed, we must first cultivate its filamentous body in order to get a large number of conchospores timely, to meet the requirements of artificial seedlings. Therefore, to understand the relationship between filamentous growth and development and environmental conditions, it is necessary to cultivate filaments. Temperature is an important environmental factor that affects the growth and development of filaments. The past research work on this area has existed
