    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60 d的铜藻[Sargassum horneri (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500~7 500 LX下均能生长,生长的适宜光强为2 500~4 500 LX;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。

    Abstract:

    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 LX. Seedlings could grow in the salinity range from 10 to 40, and the suitable salinity was 30. Long photoperiod (18L:6D) was more beneficial to growth of S. horneri seedlings. The low cultivation density (5-25·L-1) was beneficial to growth and development of the seedlings. These results provided basic technical data for artificial seeding of S. horneri to spend summer indoors.
