| 摘 要： | 在实验室条件下，用三种溶解有机磷化合物（ＤＯＰ）对浮游植物进行一次性培养，结果表明：三磷酸腺苷、甘油磷酸钠、核糖－５－磷酸均可被浮游植物吸收利用，而且ＤＯＰ与溶解无机磷（ＤＩＰ）具有相近的营养性；ＤＯＰ和ＤＩＰ共存时，浮游植物先吸收ＤＩＰ．ＤＯＰ的利用受到抑制，当ＤＩＰ耗尽后，ＤＯＰ亦被吸收；介质中ＤＯＰ浓度较低时，吸收速率更快，显示了ＤＯＰ潜在的环境效应．

| Abstract: | Results from batchculure experiments indicated that adenosine trphos-phate,sodium glycerophosphate(GP)and ribose-5-phosphate could be utilized by phyoplankton.The availability of dissolved organic phosphorus(DOP)was comparable to that of dissolved inor-genic phosphorus(DIP).It seemed thatalthough algae prefered DIP wlien DIP and DOP coexist-ed, DOP could alsobeuptaken rightafter the depletation of DIP.The uptake of DOP wa x rela-tively quicker under lower ambient concentration,implicating its potential environmental effects. |
