Reforestation of technologically polluted areas has become an increasingly important issue. In this study, seed germination capacity and survival rate and morphometric characteristics of Scots pine (Pinus sylvestris L.) seedlings grown in a magnesite-polluted soil medium were investigated in a pot experiment. Significant differences in seed field germination, sprout survival, seedling length at various growth stages, and root collar diameter of the seedling were discovered between the trial variants for the pot trial using growing media from the polluted areas and the control site. In addition, it was observed that the differences between the trial variants depended on seed origin and the level of soil pollution. The data indicate that seed germination and seedling growth were significantly reduced as the levels of pollution increased. These negative effects of the pollution tend to increase as the seedling gets older.
受污染地区的造林已成为一个日益重要的问题。本研究通过盆栽试验，调查了在菱镁矿污染土壤介质中生长的欧洲赤松（Pinus sylvestris L.）幼苗的种子发芽能力、成活率和形态计量特征。在盆栽试验中，用污染区和对照点的生长介质进行试验处理，发现种子田间发芽率、芽成活率、各生长阶段幼苗长度和幼苗根颈直径在试验处理之间存在显著差异。此外，还观察到，试验处理之间的差异取决于种子起源和土壤污染程度。研究数据表明，随着污染程度的增加，种子发芽和幼苗生长显著降低。随着幼苗的生长，这种污染的负面影响会越来越大。
