不同水温、pH条件下一氧化氮对中肋骨条藻生长的影响

摘要

The effect of nitric oxide (NO) on Skeletonema costatum growth were studied at different water temperature and pH.When water temperature was at 25～30℃ and pH at 8.20～8.30,the cultivation experiment showed the growth of Skeletonema costatum was mostly promoted when nitric oxide was added.Since the factors used in the experiment are similar with those in the sea when red tides occurres,it suggestes that NO increases the chance of red tide occurrences.The additional monitoring of NO concentration should improve the accuracy prediction of the red tide occurrence.%选用厦门海域中常见的赤潮藻中肋骨条藻,进行不同水温、pH条件下一氧化氮(NO）对该藻生长影响的实验,初步研究了水温、pH和一氧化氮含量与中肋骨条藻生长之间的关系.结果表明:水温为25～30℃和pH为8.20～8.30时,一氧化氮对中肋骨条藻生长的促进作用最为明显.因此,一氧化氮的这种促进作用将可能增加赤潮发生的机率,增加对该因子的监测将可能提高对赤潮预警预测的准确性.
