摘      要：This article discusses the patterns of NO effect on marine phytoplankton growth from chemical *** experimental results of four algae,which are Platymonas hal-golandica ***,Platymonas subcordiformis,Skeletonema costatum and Nitzschia closterium farma minutissima,are as follows:(i) In f/2 medium or f/50 medium,the growth of these four algae was obviously promoted or inhibited when nitric oxide of different concentrations was added once or twice each day during the cultivation;(ii) The NO effects on the growth of marine phytoplankton are in normal *** phytoplankton has different optimum NO concentration,which is consistent with the influence of NO on the growth of high plants;(iii) The effect of NO on Platymonas halgolandica ***,which is a food alga,is different from that on the red tide algae Skeletonema costatum and Nitzschia closterium farma *** authors put forward a new opinion that every alga has its own NO threshold *** the above results may provide new clues to understand the formation of red tide.
