Abstract
In this study,we explored the effect of pulsed phosphate supply on the growth of Phaeodactylum tricornutum in different temperature. Results showed that the frequency of pulsed phosphate supply affected the growth of Phaeodactylum tricornutum significantly,and the effect changed with temperature. Under 10 ℃,the average abundance of Phaeodactylum tricornutum decreased significantly with the increase of phosphate pulse periods( interval of input time) in low and high concentration pulse groups. Under 25 ℃,the average abundance increased significantly with the increase of phosphate pulse periods in low concentration of phosphate pulse groups,while in high concentration groups,there was no significant effect on the growth of Phaeodactylum tricornutum.
