研究了海水盐度突变对鹿角海萝孢子、孢子发生体和盘状体的影响。释放于盐度为31的鹿角海萝孢子分别移入不同盐度海水(16、21、26、31、36、39)中进行附着及培育30d;鹿角海萝孢子发生体(孢子在盐度为31海水中附着24 h)和盘状体(孢子在盐度为31海水中附着5 d)则分别移入不同盐度海水(10、16、31、52、57)中培育20 d。结果表明,鹿角海萝孢子附着、生长发育和存活的最合适盐度范围为26~36;孢子发生体生长最适盐度范围为16~31,存活合适盐度范围为16~52;盘状体生长的最适盐度范围为10~31,存活的合适盐度范围为10~57。这些结果表明孢子不同萌发阶段对海水盐度突变的适应性不同。实验结果为鹿角海萝人工育苗及增养殖提供了参考。研究亮点:海水盐度是水生生物生长发育和生存的主要影响因子之一,有关盐度对鹿角海萝孢子附着及生长发育影响的文献极少。研究了海水盐度对鹿角海萝孢子附着、生长发育的影响且研究了孢子不同萌发阶段对海水盐度的适应性。为其人工育苗及增养殖提供有价值的基础资料。
The effects of seawater salinities on the spores, sporophytes and platelets of Argiope. Pinellia ternata spores released at salinity 31 were respectively transferred into seawater with different salinity (16,21,26,31,36,39) for attachment and cultivation for 30 days. The sporophytes of Antler kohlrabi spores (salinity 31 Seawater for 24 h) and plate-like bodies (spores attached to 31 seawater for 5 days) were then transferred to saltwater (10,16,31,52,57) for 20 days. The results showed that the most suitable salinity ranged from 26 to 36 for the growth, development and survival of M. demostolae. The optimal salinity range for sporulation was 16-31 and the range of salinity for survival was 16-52. The optimum salinity range for body growth is 10-31, and the suitable salinity range for survival is 10-57. These results indicate that the adaptability of seawater salinity changes during different stages of spore germination. The experimental results provide a reference for artificial breeding and breeding of Antler heliotrope. Research highlights: The salinity of seawater is one of the main factors that affect the growth and survival of aquatic organisms. There is very little literature on the effects of salinity on the attachment and growth of sea urchin. The effects of seawater salinity on the attachment and growth of Argiope doxonin were studied. The adaptability of salinity to seawater during different stages of spore germination was also studied. For its artificial breeding and breeding to provide valuable basic information.
