Abstract
The article gives results of estimating alkaloids accumulation in the aboveground and underground plant components of family Boraginaceae (Symphytum asperum Lepech., S. caucasicum M. Bieb., Echium vulgare L., Pulmonaria mollis Wulfen ex Hornem.) depending on the ecological conditions of their habitat. Alkaloids content in the aboveground phytomass decreases in the row S. asperum > S. caucasicum > E. vulgare, and in the underground one – S. caucasicum > S. asperum > E. vulgare > P. mollis. At the end of vegetation there is an increase in alkaloids accumulation in roots and decrease in stems and leaves. Rise in air temperature and decrease in precipitation increases alkaloids accumulation in roots and scions. The level of correlation between alkaloids accumulation and microelements content in soil varies from high (Cu, Zn, Mo) to mean (Mn, Pb). The revealed regularities are recommended to discover cenopopulations of S. caucasicum, S. asperum, E. vulgare and P. mollis with maximal accumulation of pyrrolizidine alkaloids or the forecast of their accumulation in certain sections.
