Black cherry (Prunus serotina Ehrh.) is considered one of the most invasive tree species in central Europe and causes problems for both nature conservation and silviculture. Besides mechanical control treatments, a suggested control method to prevent its ongoing spread is to underplant shade-tolerant native tree species. Therefore, we combined two mechanical treatments, with underplanting of European beech (Fagus sylvatica L.) or small-leaved lime (Tilia cordata Mill.) on fenced and unfenced plots. After the first growing season, survival rates were evaluated, and selected seedlings were destructively harvested to analyze their growth performance and leaf morphology in association with the different light regimes resulting from mechanical treatments Survival rates for both seedlings were very high (>95%). Survival rates were higher on fenced plots than on unfenced plots, most likely as result of browsing. The mortality of F. sylvatica decreased with increasing light availability on fenced plots. The mortality of T. cordata did not change along the light gradient. After one vegetation period no differences with respect to biomass allocation could be detected along the light gradient. However, the specific leaf areas of both species responded similarly, decreasing with increasing light availability. In summary, both species were able to establish and survive in the dense P. serotina understory and might have the potential to outcompete the invasive alien species in the long run.

欧洲山毛榉（Fagus sylvatica L.）和小叶石灰（Tilia cordata Mill。）与黑樱桃（Prunus serotina Ehrh。）竞争的幼苗的初始存活和发育。

黑樱桃（Prunus serotina Ehrh。）被认为是中欧最具入侵性的树种之一，对自然保护和造林都造成了问题。除了机械控制处理外，为防止其持续传播的建议控制方法是种植耐荫荫的天然树种。因此，我们结合了两种机械处理方法，分别是欧洲山毛榉（Fagus sylvatica L.）或小叶石灰（Tilia cordata Mill）的种植不足。。）在有围墙和无围墙的地块上。在第一个生长季节之后，评估了成活率，并破坏性地收获了选定的幼苗，以分析它们的生长性能和叶片形态，并结合机械处理产生的不同光照方案，两种幼苗的成活率都很高（> 95％）。围栏地块的成活率高于非围栏地块，这很可能是浏览的结果。随着围栏样地光的可用性的提高，西番莲的死亡率降低。堇菜的死亡率沿光梯度没有变化。在一个植被期后，沿光梯度未检测到生物量分配的差异。但是，两个物种的特定叶面积的响应相似，随着光的可用性增加而降低。总之，这两种物种都能够在致密的体育孢子菌下层中建立并生存，从长远来看，它们有可能超过外来入侵物种。
