摘　　要：在实验室进行了一氧化氮(NO)和铁对海洋微藻中肋骨条藻(Skeletonema costatum)生长影响实验.实验结果如下:在铁限制情况下,外源NO能明显提高微藻的生长速率,增加生物量,但NO和铁对浮游植物生长影响是一个复杂的过程,它受到NO的浓度、培养液的营养水平、铁的浓度等因素的影响,同时培养液中铁的浓度也直接影响到微藻的生长和NO的释放量.因此,一氧化氮与铁在浮游植物生长过程中是交互影响的.Experiments about the effects of nitric oxide （NO） and iron on the growth of marine algae were conducted. The results of Skeletonerna costatum are as follows： under the condition of iron limit, NO can promote the growth rate of marine microalga and increase the biomass obviously; but the influence of NO and iron on growth of phytoplankton is a complicated process, which is controlled by the NO concentration, the nutrition level of the culture medium and the iron concentration, etc;however, the iron concentration has a direct influence on the growth of algae and the release capacity of NO; therefore, the effects of NO and iron on the growth of marine phytoplankton are mutual.
