摘　　要：在杭州湾上海金山海域进行了真江篱（Gracilariaverrucosa）栽培试验并在实验室内研究了温度、盐度和光照强度对真江蓠生长的影响。结果表明，温度、盐度和光照强度对真江篱的生长影响极显著（P〈0．011。真江蓠生长适宜温度为20～30℃；适宜盐度为15-25；适宜光照强度在90μmol／（mLs）左右。温度、盐度和光照强度对真江蓠生长存在显著的交互效应伊〈0．05），三者的最佳组合为温度25℃、盐度20和光照强度90μmol／（m^2．s）。海区栽培实验表明真江蓠可在杭州湾海域正常生长，全年平均特定生长率（RSG）为9．42％／d。Trial and field cultivation of Gracilaria verrucosa was conducted in Hangzhou bay and effects of ecological factors on its growth were studied in laboratory. The results showed that temperature, salinity and light intensity were significantly important factors for blade growth of G verrucosa （P 〈 0.01）. The suitable range of temperature, salinity and light intensity were between 20 and 30 ℃, between 15 and 25, and 90 μmol/（m^2.s）. And there were interactions between these three factors. The optimal culture conditions for blade culture of G. verrucosa were 25℃, salinity 20 and 90 μmol/（m^2.s） light intensity. The sporelings of G. verrucosa grew well at the Jinshan coast, Hangzhou bay and annual average specific growth rate was 9.42 %/d.
