Four ecotypes of A. thaliana (L.) (Ct-1, Pf-0, Old-1 and Per-1) from low to high latitudes were grown under different light (300 μmol photon m-2s-1 and 150 μmol photon m-2s-1) and temperature (22 and 14 °C) 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.

The solid state reactions involved in the preparation of copper oxide and zinc oxide from copper(II) and Zinc (II) oxalate of monohydrated and dihydrate respectively have been analyzed using direct current electrical conductivity measurement under the atmospheres of static air, dynamic dry nitrogen and dynamic air .The product at each decomposition stage have been characterized by infrared spectroscopy and X-ray powder diffraction. For Copper (II) oxalate monohydrated the final decomposition product in all three atmospheres was found to be CuO and intermediate step product was Cu2O .The Zinc (II) oxalate dehydrated also shows final product in all three atmospheres was found to be Zn. e conductivity measurement were supplemented with data obtained by chemical thermal (TGA and DTA),IR spectroscopy and X-ray powder diffraction analysis .
