研究了潮间带褐藻、泡囊藻和泡囊藻的净光合作用。在不同的温度、光照和盐度条件下对螺旋藻进行了测定。它们净光合作用的最佳光和温度要求分别为800-1200英尺-C(200-300微安)和20-25摄氏度。各植物的光合作用温度响应存在季节差异。也就是说，夏季植株表现出比冬季植株更强的高温耐受性和更高的温度适宜性，冬季植株的净光合作用速率在5~30℃之间高于夏季植株。泡囊褐藻螺旋藻似乎最适应低盐度条件。讨论了这三种藻类的温度和盐度要求与它们在美国新罕布夏州-缅因州大湾口系统内的当地河口分布的关系。
The net photosynthesis of the intertidal brown aigae Fucus spiralis L., F. vesiculosus L. and F. vesiculoms L. var. spiralis Farlow were determined under a variety of different temperature, light and salinity regimes. The optimal light and temperature requirements for their net photosynthesis are 800 to 1200 ft-c (200 to 300 microeinsteins) and 20 to 25C, respectively. Seasonal differences were found in the photosynthesis temperature responses of each plant. That is summer specimens showed a greater tolerance to high temperatures and a higher temperature optima than winter ones, and winter plants had a higher rate of net photosynthesis between 5 to 30C than summer plants. Fucus vesiculosus var. spiralis seems to be most adapted to low salinity conditions. The temperature and saJinity requirements ofthe three algae are discussed in relation to their local estuarine distribution within the Great Bay Estuary System of New Hampshire-Maine, USA.
