丝状体是紫菜生活史中的一个阶段。通常在秋季进行紫菜采苗,主要就是依靠丝状体所产生的壳孢子,因此培养丝状体是紫菜养殖过程的一个重要环节。一般在春季利用成熟的紫菜藻体,采取果孢子,使它钻入贝壳中生长发育成丝状体。到了秋季便形成大量的壳孢子,放散出来即萌发成紫菜。目前广大的紫菜养殖者更进一步研究,果孢子不必钻入贝壳,可以直接培养在海水中, Filaments are a stage in the life history of laver. Usually in the autumn of seaweed seedlings, mainly rely on filamentous body produced by conidia, so culture filamentous laver cultivation process is an important part. Usually in the spring using mature seaweed algae body, take the fruit spores, make it drill into the shell growth and development into filaments. In the fall, a large amount of conchospores are formed, which is sprouted into seaweed. At present, the majority of laver farmers further study, the fruit spores do not have to drill into the shell, you can directly cultured in seawater,
