本项研究试验了人工放散的蜈蚣藻(Grateloupia asiatica)与多管藻(Polysi phonia urceolata)孢子及其幼苗在不同粗糙度的附着基上的附着数量、三叉仙菜(Ceramium kondoi)、假根羽藻(Bryopsis corticulans)、酸藻(Desmarestia viridis)和尾孢藻(Urospora penicilli formis)在海水中自然附着幼苗在不同粗糙度的附着基上的附着数量;还试验了不同粗糙度附着基上不同类型的沉积物对自然附着酸藻和尾孢藻的幼苗数量的影响。试验方法是以市售塑料扎带模拟表面粗糙度不同的人工藻礁,使人工刺激后释放的海藻孢子附着在其表面后,吊挂于海中使孢子萌发;空白附着基吊挂于海水中使海藻繁殖体(孢子、合子或受精卵)附着并萌发生长。以普通海泥、高温灭活海泥、底栖硅藻3种不同沉积物覆盖于人工附着基表面,统计各种沉积物在各种粗糙度的附着基上海藻幼苗数量。结果表明,对于无鞭毛的繁殖细胞(蜈蚣藻、多管藻和三叉仙菜的孢子,假根羽藻的合子、酸藻的受精卵)萌发成的幼苗数量受附着基粗糙度影响显著;在一定范围内,两者呈正相关。而萌发自游动孢子的尾孢藻,附着基的粗糙度影响不显著。3种沉积物中,高温灭活的海泥更有利于尾孢藻和酸藻的附着。
In this study, we tested the amount of attached artificial gratellum (Grateloupia asiatica) and polysi phonia urceolata spores and their seedlings on different roughness attachments. The numbers of the attached Ceramium kondoi, Bryopsis corticulans, Desmarestia viridis and Urospora penicilli formis in seawater, respectively. The number of different types of attachment of different types of Effect of Sediment on Seedling Number of Natural Acipenser and Clostridium. The test method is that artificial algae reef with different surface roughness is simulated by a commercially available plastic cable tie, after the artificial seaweed spores released from the artificial stimulation are adhered on the surface, the spore germinates in the sea and hangs in the sea water Seaweed propagules (spores, zygotes or fertilized eggs) attach and germinate and grow. Three different sediments of benthic diatoms were covered with ordinary sea mud, high temperature inactivated sea mud, and the surface of artificial attachments was covered. The numbers of seaweed seedlings on various kinds of roughness attachments were counted. The results showed that the number of seedlings germinated from flagella-free reproductive cells (spores of centipede algae, C. multocida and C. trifoliata, zygotes from Pinus elliottii, and zygotes) was significantly affected by the roughness of the attachment base. Within the range, the two are positively correlated. However, the spores of Coccidioid spores germinated from zoospores showed no significant effect on the roughness of the attached substrates. Among the three kinds of sediments, sea mud inactivated by high temperature is more conducive to attachment of Coccoideae and acidophilus.
