Vegetation, which was formed in landfills, is influenced by many stress factors in the process of its further development. The most clearly manifested stress factors emerge in conditions of devastated landscapes. Landfills represent one of the most technogenically devastated landscapes. Vegetation is subject to the negative impact of elevated temperatures, salinity, soil contamination with heavy metals and radionuclides, drought, lack of moisture, waste gases and products of combustion. Consequently, mineral nutrition of plants is disrupted, leading to a change in colour (yellowing of leaves, leaf coveringwith brown or purple spots and so on), cessation of growth (dwarfism), formation of cracks and holes in the leaves and loss of the whole species. The photosynthetic apparatus is primarily exposed to the action of stressors. An important role in the process of photosynthesis is played by the green plant pigments - chlorophyll.As a result of studying the photosynthetic apparatus of ruderal landfill species it was established that the most resistant species, under such conditions, are Arctium lappa L. and Chenopodium urbicum L. Also, there were determined the less resistant species to technogenic pressing in the landfill impact zone, and namely: Artemisia vulgaris L., Artemisia absinthium L. and Plantago major L. |
