| Inhoud: |
Three populations of Plantago lanceolata L. were analyzed for genetic differentiation and phenotypic plasticity. Eight randomly taken samples of each population were grown at two nutrient levels and subjected to alterations in mineral supply. Growth and root respiration was followed during the experiment. With respect to all measured characteristic genetic differentiation on population level was demonstrated. Overall phenotypic plasticity of the measured characteristics and differences in estimated genetic variation were present. High relative growth rate was correlated with high root respiration. High relative growth rate was correlated with high root respiration and high Ca2+ - Mg2+ - stimulated ATPase activity in roots. Ecological significance of the results and correlation with habitat properties are discussed. |
