摘　　要：通过室内培养，研究了温度、光强、光照周期、盐度和密度对日龄为60d的铜藻[Sargassumhorneri（Turner）C．Agardh]幼苗生长发育的影响，旨在了解铜藻幼苗的适宜培育条件。结果显示：铜藻幼苗在15—30℃范围内，均能存活，适宜温度为20～25℃；在500～7500LX下均能生长，生长的适宜光强为2500～4500LX；长光照条件（18L：6D）更有利于幼苗的生长；幼苗在盐度为10～40下均能存活，适宜盐度为30。另外，幼苗的密度越低，越有利于幼苗的生长和发育，5～25棵／L的密度有益于幼苗的生长和叶片分生。上述研究结果为铜藻幼苗室内渡夏培养提供了基础技术数据。In order to get suitable cultivating conditions, the effects of environmental factors on growth of the 60-days-old Sargassum horneri seedlings were investigated in laboratory. The results showed that, S. horneri seedlings survived at 15 to 30℃, and suitable temperature range was from 20 to 25℃. The seedlings grew up under light intensity from 500 to 7 500 LX, and the better light intensity range was from 2 500 to 4 500 I.X. Seedlings could grow in the salinity range from 10 to 40, and the suitable salinity was 30. Long photoperiod （ 181.： 6D） was more beneficial to growth of S. horneri seedlings. The low cultivation density （5 - 25·L-1） was l）eneficial to growth and development of the seedlings. These results provided basic technical data for artificial seeding of S. horneri to spend summer indoors.
