摘　　要：观察了莫氏马尾藻在成熟季节雌、雄生殖托的繁殖特点、受精卵的形成、假根的发育、幼孢子体生长特征,并研究了不同附着基对采苗效果的影响。试验结果表明,莫氏马尾藻的繁殖盛期为4月中旬至5月中旬,其卵子发育属八核一卵型,假根是由基部一个细胞分化发育而来;瓷砖附苗的密度超过40株/cm2,在培育15d后,幼孢子体长度约1～2mm。The reproductive season,characteristic of male and female receptacles,oogenesis,rhizoid development and growth of young sporophytes were observed in seaweed Sargassum moclurei in coastal Maoming,Guangdong province,China in 2011.In addition,the effects of different substrates on attachment of the seedlings were studied in practice.The seaweed was found to reproduce from early April to early June and to have the 8-nucleus ova.The rhizoids were shown to be developed from one cell in the base of zygotes.The seedlings were attached at a density of over 40 individuals/cm2,and had average length of 1~2 mm during 15 day rearing.
