Biomorphological variability of Allium splendens Willd. ex Schult. in the conditions of Central yakutia

The features of different levels of anthropogenic impact on the biomorphological variability of vegetative organs of Allium splendens Willd. ex Schult. in the conditions of Central Yakutia are considered. The biological material for the study was collected in three geographically homogeneous growing areas in Central Yakutia with different degrees of anthropogenic  pressure: in natural conditions with low anthropogenic pressure, in conditions of significant anthropogenic impact and in conditions of private introduction. It has been shown that the degree  of anthropogenic pressure can be expressed in adaptive changes in plants, expressed in  morphological and biochemical characteristics, the measurable indicators of which can differ significantly from the indicators of plants growing in favorable natural conditions or under optimal conditions of introduction. Morphometric variability of traits demonstrates manifestations of the protective component of variability by increasing variability for plants experiencing high anthropogenic pressure. It has been determined that anthropogenic oppression implements adaptation mechanisms through changes in habitus, in particular, the morphometry of the vegetative mass of leaves; negative environmental conditions cause a change in the ratio of age groups of individuals and a change in the reproduction strategy. In this case, the variability  of the ascorbic acid content is more associated with the response to stress, realized through the choice of a reproduction strategy, since the amount of ascorbic acid did not correspond to the sequence of a series of morphometric variability, which can be explained by the dominance of the vegetative method of reproduction, in which biochemical processes actively occur in the underground part of the plant.
