铁对中肋骨条藻生长、色素化程度及氮同化能力的影响

以中肋骨条藻为对象，研究了铁以及铁与氮的交互作用对藻类生长、色素化程度及氮同化能力的影响。结果表明，在3x10￣8~5x10-6MOl/dM3浓度范围内，随着fE的增加，该藻对氮的吸收量增加，同化能力增大，细胞色素化程度降低，胞内氨基酸（AA）和蛋白质（Pr）含量升高，细胞生长加快，细胞生长率在fE浓度为5x10-6MOl/dM3时达最大。叶绿素A和褐色素以及胞内AA和Pr与铁浓度的对数呈正相关关系。实验还发现，当n/P为20：1时（比较40：1和10：1），铁与氮交互作用对细胞生长、色素化程度以及氮同化能力影响尤其显著：当fE浓度一定时，不同形态的氮源对藻胞内AA转化为Pr速率的影响是低氧化态氮源高于高氧化态氮
