Ecological, biological and coenotic features of common lily-of-the-valley (Convallaria majalis L.) in the conditions of Zhytomyr Polissya

A study deals with the natural habitats of Convallaria majalis L., its biological characteristics and capabilities to the seed to renewal. The features of generative and vegetative reproduction Lily of the valley in terms of Polissya are determined. A lily of valley (Convalaria majalis L., is a valuable medicinal herb, as well as an ornamental plant. The healing properties of lily of valley are caused by the presence of glycosides and saponins. The popularity of the species leads to its reduction. Nowadays the possibilities of this valuable plant application are not determined. That is why; there is a necessity to explore the habitat of this plant, its bio ecological features and the possibilities of seed restoration. The purpose of investigation is to study ecological, biological and coenotic features of a lily of valley in Zhytomyr Polissya region. Conclusions and perspectives of further researches are proved. The favorable weather conditions in 2012 allowed sufficient germ number to form. It was 200 per generative sprout in 2013. The real seed productivity in years of the research was not high and it was from 20–30 to 38 seed per species. 2013 was the least favorable year for seed formation. A lily of valley forms from 10 to 18 germs of seeds. But some part of them is able to form seeds. So, 12 germs could form 4, 3 seeds in 2011, 10 germs could produce only 4, 4 in 2012. The number of seed germs increased in 2013, but seeds were not produced. The absence of seed materials is due to the bad weather conditions during the pollination and flowering period. So, the seed restoration of a lily of valley is rather slow and random. The population is restored because of its vegetative propagation. The further researches will be focused on Convalaria majalis habitat clarification in natural conditions of Zhytomyr region in order to develop the recommendations for the proper harvesting of pharmaceutical raw materials without damaging any other natural species.
