Abstract
Four ecotypes of A. thaliana (L.) (Ct-1, Pf-0, Old-1 and Per-i) from low to high latitudes were grown under different light (300 micro mol photon m-2s-1 and 150 micromol photon m-2s') and temperature (22 and 14 degreesC) conditions to investigate their effects on phenotypic plasticity and ecotypic variations in plant growth and first flowering time. The results suggest that in A. thaliana low temperature decreases both phenotypic plasticity and ecotypic variations in first flowering time and total dry matter at final harvest under different light intensities. Relative growth rate is the most stable parameter of A. thaliana that is hardly affected by ecotype (no effect), light (no effect) or temperature (small effect) and this may one of the reason why A. thaliana is widely distributed on earth as a result of adaptations to different environments.
