Historical review was done concerning the formation and development of scientific research of the Experimental Station of Medicinal Plants over the period 1916–2016. The main stages of experimenting in the direction of “medicinal plant cultivation’’ in Ukraine were covered. Role and importance of the Experimental Station of Medicinal Plants in the scientific and methodological support of such scientific directions as breeding, seed production, cultivation technologies, pharmacognosy in medicinal plant cultivation were shown. For the needs of the branch, over 100 species of introduced medicinal plants were studied at the Station and agricultu­ral techniques of their growing were developed, in addition, more than 50 varieties of medicinal plants were crea­ted, a number of machines and devices for growing, harves­ting and initial treatment of raw materials and seeds of the most important medicinal plants was designed. Other scientific achievements of the Station were mentioned and promising areas of medicinal plant research in Ukraine were outlined.

Purpose. To study morphometric parameters of fruits (cypselae) of purple coneflower (Echinacea purpurea (L.) Moench) of ‘Zirka Mykoly Vavylova’ cultivar and pale coneflower (Echinacea pallida (Nutt.) Nutt) of ‘Krasunia Prerii’ cultivar and determine the impact of agro-meteorological factors on their performance according to long-term data. Methods. Laboratory, Mathematics and Statistics. Results. It was found that the parameters of cypselae and its weight in various types of coneflowers varied considerably from year to year. In this context the indicators of cypselae width and thickness had a larger variability as compared with the length. Mean length of Echinacea purpurea ranged from 4,57 to 6,16 mm, width – 2,30–2,97 mm, thickness – 1,74–2,28 mm. Weight of a cypselae made up 4,40–6,50 mg. Length of a fruit of Echinacea pallida was 4,57–5,74 mm, width – 2,51–3,18 mm, thickness – 1,76–2,37 mm, and a fruit weight varied from 5,65 to 7,70 mg. The correlation analysis revealed reliable connection of agro-climatic parameters and the parameters of the fruit. Conclusions. Using long-term data, the morphology of cypselaes of two Echinacea species introduced to Ukraine were studied, their basic parameters and the variability of indicators, connection with agro-climatic factors that is necessary to consider in crop growing for seeds .
