摘要
通过实验室模拟,研究Fe(Ⅲ)与 N、Mn、光、温诸环境因子对海洋硅藻中肋骨条藻生化组成和增殖的制约作用.探讨低铁有效性浓度下Fe(Ⅲ)与光、Fe(Ⅲ)与温度交互作用对藻的生化组成和能量限制的关系;Fe(Ⅲ)×N/P,Fe(Ⅲ)×Mn(Ⅱ)、Fe(Ⅲ)×Cu(Ⅱ)、Cu(Ⅱ)×Zn(Ⅱ)交互作用对藻生化组成和分裂速率的效应;以及几种藻共存下,模拟现场条件正交设计实验L_27(3^(13)).获得了该藻生长的最适宜环境因子.
Colimitation to the biochemical composition and propagation of marine diatom Skeletonema costatum by interaction of environmental factors including Fe ( Ⅲ ) , N, Mn, light and temperature was studied by laboratory simulation. Three topics were discussed: 1)the relation of the biochemical composition and energetic limitation to the interaction of Fe3+ and light, Fe3+ and temperature at low available iron concentration; 2)the effect of the interaction of Fe ( Ⅲ ) and N/ P, Fe3+ and Mn2+ , Fe3+ and Cu2+ , Cu2+ and Zn on the biochemical composition and division rate of 5. costatum; and 3) the environmental factors of optimum growth condition of S. costatum by the experiment of the othogonal design [L27 (313)] for simulating the field condition at a number of algae coexistence.
