用测定净光合放氧速率的方法研究了温度、光照和pH对锥状斯氏藻(Scrippsiella trochoidea)和塔玛亚历山大藻(Alexandrium tamarense)光合作用的影响.在不同光暗周期(L∶D)条件下培养锥状斯氏藻和塔玛亚历山大藻,研究了光暗周期对生长繁殖速率和生物量的影响.2种藻对温度的变化敏感,适宜的温度范围是17~25℃,最适温度20~22℃,低于10℃和高于30℃不能生长;锥状斯氏藻的光饱和点是400 μmol·m-2·s-1,塔玛亚历山大藻的光饱和点是650 μmol·m-2·s-1, 都属于喜高光强的微藻;2种藻对pH值的变化极其敏感,适宜的pH值范围很小,为7.0~9.0, 最适pH值7.5~8.0, 与其生活的海洋环境一致,pH值高于9.5时, 不能进行有效的光合作用,pH值10.0可致全部细胞死亡;在一定范围内,2种藻的生长速率(μ)和生物量随着光照时间的延长呈比例增加.国家重点基础研究发展计划(973计划); 中国科学院知识创新工程项目; 国家自然科学基金中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)02129-1352
