ACCUMULATION AND VARIABILITY OF THE ECDYSTEROIDS CONTENT IN MEDICINAL RAW MATERIAL OF Rhaponticum carthamoides
N.P. Timofeev
In the conditions of European North and during 17-years life cycle of agropopulation the author studied the connatural laws, influencing on productive longevity, accumulation of ecdyster-oids and variability of quality of medicinal raw material of Rhaponticum carthamoides. It was established, that the potential of productive longevity of the species is based on system of vegetative polycyclic shoots. Accumulation of effective substances (ecdysteroids) in an ontogenesis positively corre-lates with productivity of above-ground organs with the minimum registrated under drought conditions. Dynamics of the contents ecdysteroids in separate fractions and elements phytomass is combined with process of formation of propagules at which there is redistribution from old in favour of growing and developing organs.
Key words: Rhaponticum carthamoides, development in ontogenesis, productivity, medicinal raw material, contents ecdysteroids, 20-hydroxyecdysone.
