Morphological and biochemical characteristic of Tanacetum vulgare L. plant

The paper presents the results of studying the introduction of seven Tanacetum vulgare samples of different geographical origin in the Botanical garden at the Institute of Biology of Komi Scientific Center of the Ural Branch of RAS. In the first year of life the plants of tansy ordinary are in the pregenerative period, from the second year they bloom regularly and bear fruit. It has been established that in the conditions of culture the species are highly resistant and long-lived (more than 12 years). The study of the seasonal development of plants Tanacetum vulgare has showed that all samples retain phenological rhythms peculiar to this species: stretched flowering periods (33–44 days) and fruiting periods (44–52 days). Early and late samples have been identified by the timing of the entry of plants into the flowering phase. The vegetation period from the beginning of vegetation to the formation of mature fruits is 116–138 days. The growth of plants in height (109–131 cm) continues to the phase of mass flowering. The highest average daily growth (2,6–3,6 cm) was observed in the budding phase. Morphological options of generative escape have been studied. It has been revealed that the signs characterizing the flora part of the escape vary in populations at high and very high levels, which indicates the real possibility of improving the population by the method of targeted selection. The productivity and component composition of the essential oil from above-ground phytomass Tanacetum vulgare have been determined. The obtained data indicate the possibility of cultivation of this species in order to obtain high-quality medicinal raw materials. The optimal method of growing plants to create long-term plantations has been revealed.
