Morphological Variability and Biochemical Indices of Leaves in Coenopopulations of Aegopodium podagraria L. (Apiаceae, Apiales) under Various Levels of Soil Pollution with Heavy Metals

Authors: Savinov A. B., Erofeeva E. A., Nikitin Y. D.

The morphological variability, lipid peroxidation rate (LPR) and photosynthetic pigment content in the leaves of Aegopodium podagraria L. were studied in four coenopopulations growing in urban ecosystems whose soils were contaminated, to varying degrees, with heavy metals (HM): Pb, Zn, Cu, Cr. The increase of the HM level in the soil induced a decrease in the terminal leaflet size, the average number of phens (i.e. various variants of the leaf shape), and the chlorophyll content b in leaves but the percentage of rare phens increased.

Pb AND Cd INFLUENCE ON BIOCHEMICAL INDICES OF AVENA SATIVA (POÁCEAE, LILIOPSIDA)

Authors: Petukhov A. S., Khritokhin N. A., Petukhova G. A., Kremleva T. A.

This work is devoted to studying of changes of vegetable raw under Pb and Cd translocation in the tissues of oat grown on turf and sand soils at model pollution, as well the impact of Pb and Cd accumulation on the biochemical status of plants. The oat germinants accumulated the intriduced metals actively; at a combined action of Pb and Cd, synergism of the elements in the organogenic soil and antagonism in the mineral soil were revealed.
