礁膜配子体生长发育与温度、光照的关系

Effects of Temperature and Illumination on the Growth an Development of Gametophyte in Monostroma nitidum

自然海区生长的礁膜幼体，在秋季水温２０～２１℃时开始出现。１至２月份，水温低，礁膜幼体生长缓慢，３月份，水温上升，是礁膜生长的盛期，４月下旬至５月上旬，当海区水温上升至２０～２１℃时，礁膜的营养细胞开始转化形成配子囊，是礁膜繁殖的盛期。室内培养结果与此大致相同，也是水温１５℃以上时，礁膜配子体出现生长高峰，水温２０～２１℃，光照３０００～４０００１ｘ时，有利于礁膜配子体形成大量配子囊。本文还讨论了水温、光照与礁膜配子体生长发育的关系。

篢he growth and development of gametophyte of Monostroma nitidum are de-scribed in this paper，The samples were collected from the coastal waters of Jimei re-gion，According to the experimental results of the temperature and illumination in thelaboratory，we suggest the suitable temperature and illumination range on the growthand development of the gametophyte of Monostroma nitidum，and their relationship hasalso been discussed.
