Генетическое разнообразие локальных популяций Taraxacum officicnale L. в местообитаниях г. Нижний Тагил, различающихся уровнем техногенной нагрузки

Abstract

ISSR analysis of 92 samples of Taraxacum officinale L. from 5 habitats near the highly industrial city of Nizhniy Tagil was carried out. The habitats were different in the level of heavy metal pollution. Though the calculated pollution index in these habitats varied from 1.0 to 22.78 rel. units, no significant differences were revealed in genetic diversity in studied subpopulations. We suppose that plant tolerance to heavy metals in different Taraxacum officinale L. subpopulations from Nizhniy Tagil was determined by acclimations to stressors by changing morphophysiological characteristics, rather than genetic ones.
