摘要：

<正> The extracellular dissolved organic, carbon (DOC) and algal cell particlutate organiccarbon (POC) of a marine nanoplanktonic diatom Chaetoceros sp. were determined in this study. Thedaily rhythm and the influence of light and temperature on the production rate of DOC and POC were stud-ied by growing the diatom under different laboratory controlled conditions of light and temperature. Theresults showed that the production of DOC and POC varied with light and temperature and were generallyhigher at daytime than at night. Under culture conditions of 24L:0D light cycle and 3500 lx light intensi-ty, the DOC and POC reached maximum (DOC: 17. 27 mgC/L; POC: 103. 10 mgC/L). While without
