The funarioid moss species , which is threatened with extinction, was the subject of this study. The riparian habitat type of this species is often under the influence of contaminated water, and, therefore, we tested the influence of selected potentially toxic elements (PTEs), namely zinc and copper, on the development, physiological features, and survival of the species on two different accessions (German and Croatian). The results obtained showed the different resilience of the two accessions to the PTEs. Flow cytometry analyses revealed that the two accessions differ significantly in terms of genome size. However, the different amplitude of resilience to the tested PTEs, the divergence in physiological responses, and survival within two accessions of the same species are confirmed, as well as the dissimilarity of their genome size, likely associated with ploidy level difference and possibly distinct hybrid origin.
这种处于灭绝威胁中的泥炭藓类物种是本研究的对象。该物种的河岸栖息地类型常常受到受污染水体的影响，因此，我们测试了选定的潜在有毒元素（PTEs），即锌和铜，对该物种在两个不同种质（德国和克罗地亚）上的发育、生理特征及存活情况的影响。所获结果表明这两个种质对PTEs的恢复力不同。流式细胞术分析显示，这两个种质在基因组大小方面存在显著差异。然而，同一物种的两个种质对所测试PTEs的不同恢复力幅度、生理反应差异及存活情况得到了证实，其基因组大小的差异也得到了证实，这可能与倍性水平差异以及可能不同的杂交起源有关。
