中文摘要：

马尾藻类海草 thunbergii 的人工的幼苗生产是在自然资源上减轻压力的一个有效方法。为了改进接合子和还原剂的利用，幼苗，接合子版本的特征上的研究， rhizoids 的发展， germlings 的附件，和喷气洗的影响的损失被进行。接合子的百分比释放了的结果表演在开始的 60 h 与时间被增加。纳入基础的 germlings 的能力显著地被增加，与新 rhizoids 的时间特别重合出现并且伸长。germlings 的分开率显著地与开始喷气洗或洗速度的喷气的减小的时间的延期减少了。然而，在在实验使用的任何水平洗的喷气能在附件以后在 20 天以内引起 germlings 的可观的损失。我们的学习提供了一些参数在幼苗生产的早阶段优化操作。

英文摘要：

Artificial seedling production ofSargassum thunbergii is an effective way to relieve pressure on natural resources. In order to improve the utilization of zygotes and reduce the loss of seedlings, studies on the characteristic of the zygotes release, the development of rhizoids, the attachment of germlings, and the influence of jet washing were conducted. Results show that the percent of zygotes released was increased with time in the first 60 h. The capacity of germlings attached to the substratum was significantly increased, especially coincident with the time of the new rhizoids emerged and elongated. The detachment rate of germlings significantly decreased with the delay of starting time of jet washing or the reduction of jet washing velocity. However, the jet washing at any level applied in the experiment could cause considerable loss of germlings within the 20 days after the attachment. Our study provided some parameters to optimize the operation in the early stage of seedling production.
