摘要:
在实验室条件下, 以本实验室保存的萱藻丝状体为材料, 研究了温度(7—27℃), 光照强度[18—126μmol/(m2·s)]和丝状体生物量(0.1—1.6mg/ml)对萱藻孢子放散的影响。结果显示: (1) 温度为12℃最适宜萱藻孢子的放散, 在此温度下, 孢子放散量大, 放散速度快; (2) 光照强度对孢子的放散具有重要影响, 72μmol/(m2·s)为刺激萱藻孢子放散的最佳光照条件; (3) 萱藻丝状体生物量过低, 则孢子放散量较小无法达到采苗要求, 而过高亦会抑制孢子的放散, 生物量为0.8mg/ml时最适宜孢子的放散。

Abstract:
In this paper, under the condition of the laboratory, using the filaments of Scytosiphon lomentaria preserved in our laboratory as the experimental material, the effect of temperature (7―27℃), light intensity [18―126μmol/(m2·s)] and filaments biomass (0.1―1.6mg/ml) on spore releasing from unilocular sporangial branchlets of S. lomentaria were studied. Results were shown as follows: (1) 12℃ was the optimal temperature for spore releasing, at which the peak of releasing was especially high and the releasing speed was faster. (2) The light intensity had great significant influence on spore releasing, and 72μmol/(m2·s) was the best stimulating light intensity for spore releasing. (3) 0.8mg/ml was the opti-mal filaments biomass for spore releasing of S. lomentaria. A smaller quantity of filaments biomass could not meet the requirements of spore-collection, while the excessive quantity of filaments biomass could restrain the releasing of the spores.
