Abstract

The lack of knowledge on the traits related to the germination and establishment of native plant species represents obstacles to restoration. Seed mass, germination and emergence variability from two characteristic grasses (Festuca vaginata and Stipa borysthenica), and two dicots (Centaurea arenaria and Dianthus serotinus) of Hungarian sandy grasslands from altogether 34 localities were tested. Our results showed that seed mass had a significant positive effect on germinability of the dicots and on seedling emergence of all species. The laboratory germination capacity of S. borysthenica was low due to dormancy. We found a significant variability among seed traits and emergence between localities in all the species except for the germination of S. borysthenica. This significant variation among populations might be explained by local adaptation or maternal effects. We conclude that germination under laboratory-regulated conditions is a good predictor of seedling emergence for restoration projects, but limited to species with non-dormant seeds.

种子质量越大，萌发率和出苗率越高

缺乏与本地植物物种的发芽和建立相关的性状的知识，这是恢复的障碍。对来自34个地区的匈牙利沙质草原的两种特征草（羊茅和针茅）和两种双子叶植物（矢车菊和石竹）的种子质量、发芽和出苗变异性进行了测试。我们的研究结果表明，种子质量对双子叶植物的发芽率和所有物种的幼苗出苗都有显著的积极影响。borysthenica的实验室发芽能力由于休眠而较低。我们发现，除了borysthenica的发芽外，所有物种的种子性状和不同地点的出苗率都存在显著差异。人口之间的这种显著差异可以用当地适应或母体影响来解释。我们得出的结论是，在实验室调节的条件下发芽是恢复项目中幼苗出苗的良好预测指标，但仅限于具有非休眠种子的物种。
