Abstract

The problem of gene pool protection of wild plant species has gained a special relevance in modern times. In connection with the growth of population there is an increase in economic activity of human beings and their active influence on nature: wild lands plowing, overpasses plotting, construction of new and widening the boundaries of existing settlements. In addition, intensive harvesting of plants as medicinal, decorative, food, forage, etc is in progress. All this has a negative effect on the condition of wild plants: their stocks are declining, and some species are disappearing at all. A number of plants such as: spring adonis (Adonis vernalis L.), martagon lily [Liliumpilosisculum(Freyn)) Miscz,L.], butterfly orchid [Platantherabifolia(L.) Rchb], PaeoniaanomalaL. , rosewort (Rhodiolarosea L.) in their status, they belong to the group of rare and endangered species, they are listed in the Red Book of the Middle Urals, and their conservation requires introduction.

The study found that the species studied are culturally resistant, adapting well to new conditions. During the growth process, they went through all phenological phases, ending the development cycle with the fruiting phase with seed formation. Seeds with high enough sowing properties was provided by martagon lily, for which self-seeding is characteristic; low germination of seeds is noted in Rhodiolarosea L. and Platantherabifolia (L.)
