Аннотация:
Проведена оценка состояния популяций и морфологическая характеристика растений Viola incisa Turch. в Иркутской области и Республике Алтай. Изучен онтогенез растений в популяции Иркутской обл. Выделены критерии для определения возрастных состояний. Определена демографическая структура популяции. Высказана гипотеза о возможных путях формирования устойчивой популяции в Иркутской обл. Необходим мониторинг исследованных сообществ и организация охраны популяции V. incisa в Республике Алтай.

Ключевые слова: редкий вид, онтогенез, онтогенетический спектр, демографические индексы, Иркутская обл, Республика Алтай

Название на английском: The state of natural populations of Viola incisa (Violaceae) in South Siberia

Аннотация на английском:
Viola incisa Turch. is included in the Russian and many regional Red Data Books. The state of its populations was estimated in the Irkutsk Region and in the Altai Republic. The ontogenesis of the Irkutsk population was studied. Mature generative plants have the greatest number of leaves (up to 24 leaves) and the longest leaves (up to 26.5 cm), their leaf blade being longer than a half of the whole leaf. Blade shape in juvenile and subsenile plants is broadly triangular, that of generative plants is narrowly triangular. The particularity with significant rejuvenation was observed. Based on morphological and demographic analyses, the studied populations were determined as young. The Irkutsk population had stable status even in the absence of recommended measures. Lack of fruits in two populations is possibly connecte with hybrid origin of V. incisa. Possible ways of formation of the stable population in Irkutsk Region were suggested. Monitoring of the studied communities and measures for conservation of the V. incisa population in the Altai Republic are necessary.
