在实验室条件下对亚洲蜈蚣藻（Grateloupia asiatica Kawaguchi et Wang ）的孢子发育进行了研究，同时探讨了温度（5～30℃）和光照强度（10～200μm o l·m -2·s-1）对孢子发育的影响；追踪观察了生活史的各个阶段。结果表明：（1）亚洲蜈蚣藻的孢子发育类型为“间接盘状体”型（有丝状体出现）；（2）孢子发育和盘状体生长的最适温度为25℃；（3）光照强度（80μmol·m -2·s-1）条件下孢子的发育和盘状体生长速度最快；（4）生活史由果孢子体、配子体及四分孢子构成，孢子体和配子体在形态上相同，属于同型世代交替。

Under laboratory conditions for Grateloupia asiatica Kawaguchi et Wang of spores develop-ment was studied .At the same time ,this paper discussed the impact of spores development the tem-perature (5~30 ℃) and light intensity (10~200 μmol · m -2 · s-1 );T he life cycle stages of tracking observation .The results show that :(1)G .asiatica were “mediate discal type”(with filamentous fronds);(2)the grow th of optimum temperature of spores development and discoid crust is 25 ℃ ;(3) light intensity (80 μmol · m -2 · s-1 ) under the condition of the grow th of spore development and the discoid crust growth speed ;(4)G .asiatica showed a life history with gametophytes ,carposporophytes and tetrasporophytes ,the sporophyte and gametophyte same on morphology ,and a typical homotypic alternation of generations .
