Abstract The costs of Biscutella laevigata adaptation, a facultative metallophyte, to an environment polluted with heavy metals were established by analyzing the differences in embryological processes between plants from two populations in Southern Poland (a mountain, in the Tatra Mountains and calamine, in Boleslaw). Disturbances in male and female lineage development occurred in plants from both populations. The higher frequency of degenerations in plants from the calamine population could be interpreted as a strategy to save resources limited by the environment. The distribution of high-esterified homogalacturonan detected by LM20 antibody in the cell walls of embryos from the calamine population could be part of a resistance/defense system. The results from both populations indicate that B. laevigata has already developed adaptation/tolerance, enabling maintenance of the calamine population over time. Tolerant species could be an important source for revitalization and/or phytoremediation of polluted environments.

金属植物 Biscutella laevigata L.（十字花科）的种系发育和种子集。

摘要 通过分析波兰南部两个种群（位于塔特拉山脉的一座山和位于博莱斯瓦夫的炉甘石）的植物之间胚胎发育过程的差异，确定了兼性金属植物 Biscutella laevigata 对重金属污染环境的适应成本. 雄性和雌性谱系发育的紊乱发生在两个种群的植物中。炉甘石种群的植物退化频率较高可以解释为一种节省受环境限制的资源的策略。LM20 抗体检测到的高酯化同型半乳糖醛酸在炉甘石群体胚胎细胞壁中的分布可能是抵抗/防御系统的一部分。两个种群的结果表明 B. laevigata 已经发展出适应/耐受性，随着时间的推移，能够维持炉甘石种群。耐受物种可能是污染环境恢复和/或植物修复的重要来源。
