The chemical composition and productivity Vaccinium myrtillus L. under influence industrial pollution
Abstract
The content and nature of the distribution of chemical elements (S, Mn, Fe, Zn, Cu, Co, Cr, Ni, Pb and Cd) and phenolic compound were determined in the above-ground and underground parts of bilberry (Vaccinium myrtillus L.), grown on the background and technogenic polluted territories of the Southern Baikal region. Plants and soil were sampled at polluted site situated 0.5-1.0 km from Baikal Pulp and Paper Mill (East Siberia) and at a relatively clean site. It was shown that in V. myrtillus Fe, Ni, Cr, Pb and Cd accumulated in roots, Mn and Zn accumulated in stems, S and Co in leaves and Cu in fruits in background conditions. Should be noted, the intensity of the absorption elements of the reproductive organs V. myrtillus is lower than of the vegetative one. The content of phenolic compounds in plants bilberries decreases in the order leaves < stems < berries < roots, flavonoids – leaves 2. It was show the berries productivity depends on number and weight berries on the shrub (r = 0.55-0.68, p
