某些藻类在生殖发育期间能分泌某些激素,影响有性过程。在绿藻门中,RawitscherKwnkel的工作指出鞘藻属的有性过程受所产生激素的控制和调节。starr等发现在正常条件下培养的团藻属克隆需经雄性克隆所释放的物质的诱导,方能产生出有性的克隆。Starr等(1974)和Kochert等(1974)分别对此物质进行分离和提纯后,经测定证实为糖蛋白类物质(glycoproteir)。在褐藻门中已在水云属和墨角藻属等发现其卵子能分泌某种物质,吸引精子向卵的方向游动,使受精率增加。在海带属中,Lüning和Müller(1978)发现有6个物种所分泌的性诱引素(Sex attractant),不仅可吸引精子而且还能促进精子从精子囊中释放。在褐藻的酸
Some algae during reproductive development can secrete some hormones, affecting the sexual process. In Chlorophyta, the work of RawitscherKwnkel pointed out that the sexual process of the genus Saccharomyces is controlled and regulated by the hormones produced. Starr et al found that clones of the genus Nephrolepis cultured under normal conditions require the induction of substances released by the male clones to produce sexual clones. This material was isolated and purified by Starr et al. (1974) and Kochert et al. (1974), respectively, and was confirmed to be a glycoproteir. In the brown algae door has been found in the genus Merino and Fucus genus and other eggs can secrete a substance that attracts sperm swimming in the direction of the egg to fertilization rate. Lüning and Müller (1978) found that Sex attractant secreted by six species not only attracts sperm but also promotes the release of sperm from the sperm capsule. Acid in brown algae
