温度和盐度对浒苔生长和光合生理特性的影响
COMBINED EFFECTS OF SALINITY AND TEMPERATURE ON THE GROWTH AND PHOTOPHYSIOLOGICAL PERFORMANCES INULVA PROLIFERA
摘要
Abstract
The tidal influence, monsoon, freshwater inputs and other environmental factors impact temperature and sa-linity in tidal zone where the macroalgae grown. The current study evaluated effects of temperature and salinity on the growth and photophysiological performance of macroalgae.Ulva prolifera were cultured in 4 conditions including the ambient condition (22 and 25 salinity), normal temperature and low salinity (22 and 15 salinity), low temperature and normal salinity (15 and 25 salinity) and low temperature and low salinity (15 and 15 salinity) for 6 days to measure the growth, chlorophyll content, chlorophyll fluorescence parameters, SOD activity and soluble protein content. Our re-sults showed that temperature did not impact the growth ofU. prolifera at low temperature, and that low salinity de-creased the growth ofU. prolifera at normal temperature, and that temperature slightly but not significantly mediated the growth ofU. prolifera at low salinity, and that low temperature significantly reduced the growth ofU. prolifera at normal salinity. Temperature but not salinity significantly impact theFv/Fm.U. prolifera cultured in low temperature and low salinity condition showed higherFv′/Fm′, NPQ, SOD activity and soluble protein content.关键词
