摘　　要：本文在实验室批量培养,室外小池大量培养和塑料大棚大面积培养的基础上,研究了植物激素2,4-D刺激鱼腥藻增殖的效应。浓度在0.01—2.00μg/mL范围内都具有刺激鱼腥藻增殖的效果,随着浓度增加,这种效果降低。品质分析结果表明,0.01μg/mL2.4-D可提高蛋白质和叶绿素a的含量;浓度为0.05μg/mL时,二者的含量与对照相差不大;浓度达到0.1μg/mL时,二者的含量降低。本文提出,2,4-D刺激鱼腥藻增殖的应用浓度应在0.05μg/mL以下,以0.01μg/mL效果最佳。The present investigation deals with 2,4-D dichlorophenoxy acetic acid(2,4 D)on the multiplication of Anabaena at batch culture in laboratory, mass culture of algae nursery bed in outdoor and large-scale culture in polyethene sheet canopy. Multiplication of Anabaena was treated with 2,4-D at the concentration range 0.01—2.00μg/mL, and the effects of stimulation in lower concentration is better than that of higher one.when the concentration of 2, 4-D is 0.01μg/mL, contents of protein and chlorophyll a increase. At the concentration of 0.05μg/mL, the contents of protein and chlorophyll a are similar to the control. But the contents of protein and chlorophyll a decline when the concentration of 2,4-D increase up to 0.1μg/mL. The present investigation suggests that concentration of 2,4-D used for multiplication of Anabaena should be less than 0.05μg/mL, the optimal concentration is 0.01μg/mL.
