The functional properties of the invasive Heracleum sosnowskyi were compared with those of the native Heracleum sibiricum. The leaf and root traits, as well as those of a whole plant and of the mycorrhiza formation, were studied. H. sosnowskyi can fulfill the high-productivity potential only under the optimum availability of resources (especially water), while it is poorly adapted to maintain a high physiological activity under the unfavorable soil conditions. An important component of the H. sosnowskyi invasiveness is an ability to utilize rapidly resources in both the above- and underground areas at the optimum conditions.
将入侵物种刺果毛茛的功能特性与本地物种西伯利亚毛茛进行了比较。研究了叶片和根系特征，以及整株植物和菌根形成的特征。刺果毛茛只有在资源（尤其是水）最佳可利用性的条件下才能发挥其高生产力潜力，而在不利的土壤条件下，它很难维持较高的生理活性。刺果毛茛入侵性的一个重要组成部分是在最佳条件下能够迅速利用地上和地下区域的资源。
