在受控环境下，比较了遮阳生境和遮阴生境下杜尔卡玛单株的光合响应特性。在模拟自然生境光强、水分有效性和日温度振幅差异的12种环境条件下，测量了光饱和光合速率和与光合作用和生长性能相关的7个附加参数。在不同的光照环境和遮荫环境中，可能没有生态型的分化。除1只外，野外收集的所有个体都能够成功地居住在收集物种的所有光环境中。
The photosynthetic response properties of individuals of S. dulcamara L. collected from sun and shade habitats were compared in controlled environments. Light-saturated photosynthetic rates and 7 additional parameters associated with photosynthetic and growth performance were measured over a range of 12 environmental conditions that simulated natural habitat differences in light intensity, moisture availability and daily temperature amplitude. There may be no ecotypic differentiation with respect to the sun and shade environments from which the individuals were collected. All but 1 of the field-collected individuals were capable of successfully inhabiting the full range of light environments from which the species was collected.
