| 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.

| Abstract: | Experiments about the effects of nitric oxide(NO) and iron on the growth of marine algae were conducted.The results of Skeletonema 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. |
