Особенности водного обмена и фотосинтеза кустистых лишайников рода Cladonia на территории Курганской области

Abstract

This article is devoted to studying of water exchange and photosynthesis in lichens of the genus Cladonia. Studies have shown differences in the intensity of flow of physiological processes (water metabolism, photosynthesis) lichens bushy Lichen genus Cladonia depending on aspectual particularities and ecological conditions. The more high return of water and absorption of water, pigment content is is characterized by C. alpestris. The lichens collected with open well illuminated place from the pine forest «ecological tropes» are characterized greater return and absorption of water, intensity of the photosynthesis, than lichens, collected under the canopy of pine forest. The intensity to assimilations of the carbon dioxide of lichen reaches the maximum under full saturation by their water and on background of the more high contents pigment. Tallomes of lichensof the genus Cladonia, collected with open well illuminated place are characterized by more high contents of of chlorophyll a and carotenoids.
