紫菜生活史分丝状体和叶状体两个生长发育阶段。条斑紫菜丝状体成熟后放散的壳孢子萌发成叶状体,幼叶状体又可放散单孢子,单孢子也萌发成长为叶状体,在适宜条件下可以重复几代。可见,虽然壳孢子是叶状体养殖的苗源,单孢子苗在条斑紫菜养殖上也占有很重要的地位。 目前,国内外对紫菜壳孢子苗的生态习性已经作了一些研究,对叶状体形成,放散 Seaweed life history sub-filamentous and frond two growth stages. Przewalsla spectabilis spores germinate into phyllodes spores after maturation, and the young fronds can disperse the spores and the spores grow to fronds, which can be repeated for several generations under appropriate conditions. Can be seen, although the conchospore is the seedling source of fronds, single spore seedlings in Porphyra culture also plays a very important position. At present, domestic and foreign ecological habits of laver spore seedlings have made some research on the formation of fronds,
