DescriptionThe effect of acidic precipitation on vegetation is the result of an interaction between the acid and the plant. The metabolism of plants is dependent on optimal pH-values, which are maintained by regulation. There are differences in the effectiveness of regulation under such exogenous influences as acidic precipitation. These differences can be related to the resistance of plants to acidic precipitation or to certain pathogenic fungi. Such differences were measured as buffering capacity of homogenized leaves during titration with acid. There are significant differences in buffering capacity between clones in Pinus spp. and Picea abies. A highly significant variance in buffering capacity also was found among families of P. abies. Calculations of genetical parameters show that the phenotypical variance of buffering capacity is governed mainly by genetical factors.
