| 摘 要： | 为研究一氧化氮(NO)与金属铜对海洋微藻生长的影响,选用中肋骨条藻(Skeletonema costatum)和裸甲藻(Gymnodinium sp.)进行了不同NO和Cu浓度、不同添加方式的室内培养实验,初步探讨了它们的作用机制.结果表明:一次性或每天两次加入不同浓度NO(10-5~10-10mol/L),对微藻的生长表现出不同程度的促进或抑制作用,呈"两面性".一次性加入1.4、0.001 4μmol/L NO或每天两次加入0.001 4μmol/L NO,对处于正常生长或铜胁迫下微藻的生长都有促进作用,表现出NO能"抵御"铜对微藻生长的抑制作用.NO对微藻的生长具有重要的调控作用,这可能与NO所具有的抗氧化作用有关.

| Abstract: | In order to study the influence of nitric oxide(NO) and copper ion on marine algae growth,Skeletonema costatum and Gymnodinium sp.were incubated when adding different concentrations of NO and copper with different addition methods,and the preliminary functional mechanism was discussed.Experimental results showed that when adding different concentrations of NO(10-5～10-10 mol/L) only once at the beginning or twice a day during the cultivation process,marine algal growth was obviously promoted or inhibited,which showed the phenomenon of "dual effect".When adding 1.4,0.001 4 μmol/L NO only once at the beginning or 0.001 4 μmol/L NO twice a day,the algae growth was enhanced both in the natural condition and in the metal stresses,and NO could counteract the inhibition caused by copper ion during the algae growth.NO plays an important role in the regulation and control of the marine algae growth,which may be correlated with the antioxidation of the bioactive molecule NO. |
