Self-compatibility and auto-fertility are likely to promote establishment and persistence of plants in novel environments, but empirical evidence is scarce. Therefore, three studies are proposed. (1) To test whether invasiveness of alien plant species is hampered by pollen limitation, we will experimentally supplement pollen on ten con-familial triplets of native, non-invasive alien and invasive alien species in central Europe. (2) To test whether self-compatible and auto-fertile plant species are globally more invasive, we will create and analyse a quantitative database on self-compatibility and auto-fertility. (3) To test whether novel environments can induce plastic changes in self-compatibility and auto-fertility, we will assess these characteristics under ambient and elevated temperatures, as predicted for the future, for six con-familial triplets of native, non-invasive alien and invasive alien species. Overall, these studies will provide important insights in the role of plant reproductive characteristics for establishment and persistence in novel environments, and how novel environments may affect these plant reproductive characteristics.

自亲和性和自育性可能促进植物在新环境中的建立和持续，但缺乏经验证据。因此，本文提出三项研究。(1)为了验证外来植物物种的入侵是否受到花粉限制的阻碍，我们将在10个中欧地区的本地、非入侵外来和入侵外来物种的家族性三胞胎上进行实验补充花粉。(2)为验证自亲和自育植物物种是否具有更强的全球入侵性，我们将建立和分析自亲和自育的定量数据库。(3)为了验证新环境是否能诱导自相容性和自生殖的可塑性变化，我们将根据未来的预测，在环境和高温下评估6个本地、非入侵外来和入侵外来物种的同家族三胞胎的这些特征。总的来说，这些研究将为植物生殖特征在新环境中建立和持续的作用以及新环境如何影响这些植物生殖特征提供重要的见解。
