摘要 | Carbon, nitrogen, phosphorus, silicon composition of cultured two different sized phytoplankton common species of Thalassiosira rotula and Skeletonema costatum from the Jiaozhou Bay were measured. Carbon, nitrogen, phosphorus, silicon contents in cell were. obvious higher in T. rotula than in S. costatum, but the percents of nitrogen, phosphorus, silicon contents in cell dry mass in T. rotula were lower than those in S. costatum. The dry mass concentrations of nitrogen,phosphorus,silicon in S. costatum were much higher than those in T. rotula, particularly silicon, the former was 6.4 times of the latter, showing that S. costatum could more assimilate these elements. Especially, S. costatum had competitive dominance for assimilating silicon, which is beneficial to its becoming a major dominant species in relative short silicon of the Jiaozhou Bay. There were some differences in numerical value of nutrient ratios both laboratory-cultured phytoplankton and different sized suspended particulates (mainly phytoplankton) in the Jiaozhou Bay, which was caused by the changes of environment. High contents of carbon, nitrogon and relative low phosporus,silicon, high molar ratio of nitrogen to phosphorus (far higher than Redfield value) and low ratio of silicon to phosphorus and silicon to nitrogen (far lower than Redfield values) in the two diatoms and different sized suspended particulates were consistent with those in the seawater. Relative short silicon in the seawater and phytoplankton showed that silicon was possibly affectting phytoplankton growth in the Jiaozhou Bay.; Carbon, nitrogen, phosphorus, silicon composition of cultured two different sized phytoplankton common species of Thalassiosira rotula and Skeletonema costatum from the Jiaozhou Bay were measured.
