Дан анализ качественных и количественных палинологических характеристик в условиях антропогенно изменённых ландшафтов Донбасса по видам-индикаторам: Erigeron canadensis L., Cirsium arvense (L.) Scop., Grindelia squarrosa (Pursh.) Dunal и Achillea millefolium L. Установлено, что в градиенте повышения трансформирующей нагрузки изменяются геохимические показатели, а также в аспекте мужского гаметофита происходят существенные структурно-функциональные перестройки, - это рассматривается как индикаторное свойство растений и ответная реакция на факторы нео-специфического стресса, обусловленного высоким уровнем милитаризации в Донецком регионе. Высокую диагностическую информативность фактора полемостресса имеют характеристики скульптуры и орнаментации поверхности зрелого пыльцевого зерна, интенсивности окрашивания и целостности экзины. Выбранные виды растений имеют разные стратегии выживания в неблагоприятных условиях геохимического и геофизического контраста: от высокой эксплеренции, до плотного задернения нарушенного почвенного горизонта.

The analysis of qualitative and quantitative palynological characteristics in the conditions of anthropogenically changed landscapes of Donbass is given for the indicator species: Erigeron canadensis L., Cirsium arvense (L.) Scop., Grindelia squarrosa (Pursh.) Dunal and Achillea millefolium L. It is established that in the gradient of increasing transforming load, geochemical indicators change, and in the aspect of male gametophyte, significant structural and functional rearrangements occur - this is considered as an indicator property of plants and a response to factors of neo-specific stress caused by the high level of militarization in the Donetsk region. The characteristics of sculpture and ornamentation of the surface of a mature pollen grain, the intensity of coloring and the integrity of the exine have high diagnostic information content of the polemostress factor. The selected plant species have different survival strategies in unfavourable conditions of geochemical and geophysical contrast: from high explerence to integumentary of the disturbed soil horizon.
