To aid early warning and prevent the outbreak of green tides in the Yellow Sea, both the growth and photosynthetic performance of Ulva prolifera were studied after culture in different temperatures (18, 22, and 26 °C) and light intensities (44, 160, and 280 μmol m·s). Furthermore, their instantaneous net photosynthetic performance (INPP) was studied to determine the resulting environmental acclimation. The relative growth rates of U. prolifera significantly decreased in response to increasing temperature, while they increased with increasing light intensity. Culture at higher light intensities significantly increased INPP, while higher temperatures decreased the INPP. Culture at lower temperatures lowered INPP, while increased growth temperature increased the effect. These results suggest that high temperatures during the cold season inhibited U. prolifera growth. However, low temperatures during the warm season increase biomass and may cause a large-scale green tide. These results help to understand the correlation between U. prolifera blooms and extreme weather.
为了帮助黄海地区进行赤潮的早期预警和预防，本研究在不同温度（18、22 和 26°C）和光照强度（44、160 和 280 µmol m·s）下培养石莼后，研究了其生长和光合作用性能。此外，还研究了其瞬时净光合性能（INPP），以确定由此产生的环境驯化。石莼的相对生长率随温度升高而显著下降，而随光照强度增加而增加。在较高的光照强度下培养显著增加了 INPP，而较高的温度则降低了 INPP。较低的温度会降低 INPP，而较高的生长温度则会增强这种效果。这些结果表明，冬季高温会抑制石莼的生长。然而，夏季低温会增加生物量，并可能导致大规模的赤潮。这些结果有助于理解石莼爆发与极端天气之间的相关性。
