摘要
研究了光照和温度联合作用下磷酸盐脉冲输入对三角褐指藻生长的影响.结果表明随着温度的升高,磷酸盐脉冲输入频率对三角褐指藻生长的影响趋于显著,连续添加磷酸盐和低频脉冲更有利于三角褐指藻快速增长,但较高的光照强度[125μmol/(m2?s)]和较高的温度(18℃、25℃)同时作用将抑制三角褐指藻的磷酸盐吸收能力.研究证实了温度、光照和脉冲对三角褐指藻的生长存在交互影响.
Effect of phosphate pulsed supply on the growth of Phaeodactylum tricornutum under different temperature and light levels wes explored. More significant effects of pulsed phosphate supply on Phaeodactylum tricornutum under higher temperature levels were found. The continuous phosphate supply and low-frequency pulses promoted rapid growth of Phaeodactylum tricornutum. However, the interactions of high temperature （18℃, 25℃）and light intensity [125μmol/（m2.s）]would inhibit the absorption ability of Phaeodactylum tricornutum on phosphate. Results confirmed that temperature, light and pulsed phosphate supply had significant interactive influences on the Phaeodactylum tricornutum.
