Abstract

The stability of development (in terms of the fluctuating asymmetry of leaf measurements) was studied in populations of the silver birch Betula pendula from different parts of the range under varying degrees of anthropogenic impact (under the influence of industrial facilities in the territory of Khakassia and the Belgorod region and in the urbanized environment in Yoshkar-Ola, Yakutsk, and Moscow). The data obtained show an increase in the degree of disturbance of the developmental stability as adverse effects increase, from a conditionally normal state to a critical one. In habitats with a similar degree of deviation of conditions, a similar reaction of plants is observed, despite the considerable spatial remoteness and various kinds of impact.

通过在自然和人为条件下发育的稳定性评估植物状况（波动性的桦木，桦木的叶特征的不对称性）

摘要

在不同程度的人为影响下（在哈卡斯州和哈萨克斯坦地区的工业设施的影响下），研究了桦木桦的种群在不同范围内的发育稳定性（根据叶片测量的不对称性）。别尔哥罗德州以及约什卡尔奥拉，雅库茨克和莫斯科的城市化环境）。从有条件的正常状态到临界状态，获得的数据表明，随着不良反应的增加，发育稳定性受到干扰的程度也随之增加。在条件相似程度不同的栖息地中，尽管空间遥远且影响多种，但观察到的植物也有类似的反应。
