比较的意义和同步性的形态和光合作用的调整的抱叶眼子菜，以岸特定的环境进行了研究植物生长在最大深度的定居的北方和巴拉顿湖南岸。海岸特定的环境并没有影响植物生理参数：光合作用在两岸的高，加上低呼吸和补偿辐射。相比之下，海岸之间的形态和习惯的差异是显着的：植物的背阴，北方海岸有较轻的，但较大的叶子，和较长的节间集中在植物的顶端。因此，眼子菜属植物的生理变异并不随其形态分化而变化。
Comparative significance and synchronicity of morphological and photosynthetic adjustments of Potamogeton perfoliatus to shore-specific environments were examined on plants growing at the maximum depth of colonisation of the northern and southern shores of Lake Balaton. The shore-specific environments did not affect photophysiological parameters: the photosynthesis of plants on both shores was high, coupled with low respiration and compensation irradiances. In contrast, morphological and habitual differences between the shores were significant: plants of the shady, northern shore had lighter, but larger leaves, and longer internodes concentrated in the apex of the plants. Thus, photophysiological variability of Potamogeton does not follow its morphological differentiation.
