为预警和预防黄海绿色潮的发生，研究了不同温度（18、22和26 °C）和光照强度（44、160和280 μmol m−2·s−1）下培养的石莼（Ulva prolifera）的生长和光合性能。此外，他们的瞬时净光合性能（INPP）进行了研究，以确定由此产生的环境驯化。美国的相对增长率。proliferation随着温度的升高而显著降低，而随着光照强度的增加而增加。培养在较高的光照强度显着增加INPP，而较高的温度降低INPP。培养在较低的温度降低INPP，而增加生长温度增加的效果。这些结果表明，在寒冷的季节高温抑制U。增殖生长然而，温暖季节的低温会增加生物量，并可能导致大规模的绿色潮。这些结果有助于理解U.以及极端天气。
To aid early warning and prevent the outbreak of green tides in the Yellow Sea, both the growth and photosynthetic performance ofUlva proliferawere studied after culture in different temperatures (18, 22, and 26 °C) and light intensities (44, 160, and 280 μmol m−2·s−1). Furthermore, their instantaneous net photosynthetic performance (INPP) was studied to determine the resulting environmental acclimation. The relative growth rates ofU. proliferasignificantly 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 inhibitedU. proliferagrowth. However, low temperatures during the warm season increase biomass and may cause a large-scale green tide. These results help to understand the correlation betweenU. proliferablooms and extreme weather.
