Abstract
Comparative analysis of the macro and trace element composition of fruit, leaves and stems of the plants was carried out with respect to the content of mineral nutrition elements in the soils in the natural population of the Altai subspecies of blue honeysuckle (Lonicera caerulea subsp. altaica) in the local zone where disjunctive geological structures are concentrated in the valley of the Kyzyl-Yaryk river (the Altai Mountains, the North Chuya Ridge). Substantial variations of the total content of macro and trace elements Ca, Al, K, Na, Sr, P, Mn, Ba, B, Zn, Cu, Cr and Ni, the mobile forms of Ca, Sr, Fe, Mn, Cu, Cr, Ni, Co, Na in the soils and soil acidity (pH 4.5-6.7) were revealed at the regions differing from each other in the volume activity of radon emission field (262-1162 Bq/m3). Micropopulations of L. caerulea subsp. altaica at these regions differed from each other in the level of accumulation of Сu, K, P, Na, Mo, Cr, P, Sr, Si in plant organs, and in the physiologically essential ratios Cu/Zn, Fe/Mn and K/Ca. An increase in the Cu/Zn ratio in plant organs had a significant effect on a decrease in fruit size, number of seeds in fruit, their germination capacity, and an increase in the seed germination power. The seed germination power is also in significant positive correlation with the level of Ca, Mg, Cr, Cu, Sr, Pb accumulation in leaves and stems, and with the Fe/Cu ratio. The content of K in fruit is in significant negative correlation with seed germination power.
