The article presents the results of long-term research on the adaptive potential of plants of the genus Iris of the family Iridaceae in the Northern forest-steppe of Western Siberia. An assessment of the morphobiological features of irises was carried out, the timing of flowering and the amount of positive temperatures necessary for the onset of such phenological phases of development as regrowth, budding, flowering and fruiting were determined. The indicator role of phenolic compounds and peroxidase in iris leaves during seasonal development was revealed. The studied indicators can be used as an informative parameter for evaluating the state of plants for phyto-indication and introduction.
