Phenotypical plasticity of the moss Ceratodon purpureus (Hedw.) Brid. under the conditions of technogenically transformed environment

Abstract

Changes in morphological and gender structure of turfs, seasonal dynamics of the photosynthetic pigments and photochemical activity of isolated chloroplasts in moss Ceratodon purpureus (Hedw.) Brid. under the conditions of techogenic environment: recultivated dump of mine “Nadia” (Sosnivka) in Chervonograd mining region and PJSC “Mykolayivtsement” (Lviv region) are discussed. It was found that increase in leaf amount on the shoot and leaf area index is one of the water saving mechanisms in turfs and photoprotection of moss pigment system. Study of peculiarities of the seasonal variability of chloroplasts photochemical activity and quantitative and qualitative composition of photosynthetic pigments (chlorophylls, carotenoids, pheophytins) and total anthocyanins content provided an opportunity to find out multilevel aspects of adaptive strategy C. purpureus under unfavorable microclimatic and edaphic conditions of technogenic environment.
