在不同的光强度、温度和盐度条件下，褐藻类褐藻 Ascophyllum nodosum (L.) Le Jolis 及其分离的 ecad scorpioides (Hornemann) Hauck 的生理反应相似。最佳光照和温度要求为 206 个微爱因斯坦（850 英尺-摄氏度）和 18 至 21°C。没有注意到最佳光照的季节差异；相比之下，两种植物的冬季标本都显示出 10 至 25°C 之间的净光合作用平台期，而夏季的最高温度则高达 18 至 21°C。总体而言，夏季植物的净光合作用率高于冬季植物。两种泡叶植物都表现出广泛但可变的盐度耐受性，净光合作用最低为 18%0，最高效率为 0 至 40°/00。
The physiological responses of the fucoid brown alga Ascophyllum nodosum (L.) Le Jolis and its detached ecad scorpioides (Hornemann) Hauck were similar under varying conditions of light intensity, temperature and salinity. The optimal light and temperature requirements were 206 microeinsteins (850 ft-c) and 18 to 21 C. No seasonal differences in light optima were noted; in contrast, winter specimens of both plants showed a plateau of net photosynthesis between 10 to 25 C, versus a conspicuous maximum of 18 to 21 C during the summer. Overall, summer plants showed a higher rate of net photosynthesis than winter specimens. Both Ascophyllum plants exhibited a broad but variable tolerance to salinity, with lowest net photosynthesis at 18%0 and maximum efficiency at 0 to 40°/00.
