Phenology of the Antyllis vulneraria L. in Moscow region

Abstract

The research topic is the study of the biological characteristics of the local flora protected species Anthillis vulneraria L., under conditions of field experience in the Moscow region. The purpose of this research was to study the phenological cycle and the influence of meteorological factors on the timing and duration of phenophases. In the period from 2017 to 2022, a reduction in the duration of the shoot regrowth period, budding and flowering phases was revealed due to an increase in the sum of average daily temperatures and a decrease in precipitation. The resistance of plants to the conditions of the winter season in plants of the 1st-2nd year is 60-84 %, in plants of the 3rd year 50 %. A. vulneraria goes through a full phenological cycle in 175-190 days, blooms and bears fruit annually, forms a viable self-seeding, starting from the 2nd year of vegetation, grows in one place for up to 6 years, with the lifespan of individual plants up to 3 years. Pre-sowing preparation of seeds - wet stratification for 2 months, increases their germination rate to 53-65 %. The results of the study are relevant for maintaining the number of A. vulneraria that is a protected species of local natural flora in the Moscow region.
