Abstract: In order to promulgate Arsbidopsis Pumila’s plasticity response physiological biochemistry characteristic, this research uses the different strength of illumination to process Arsbidopsis Pumila and studies its main physiological biochemistry target. The result indicated under certain condition, the chlorophyll content increases along with the growth irradiance increased. In protective enzymes systems, catalase activeness is inconsistent with the growth irradiance intensity change. The cytomembrane penetrability also increases along with the strength of growth irradiance. In the Arabidopsis Pumila organization, the enhancement of antioxidants was a protective pathway against high growth irradiance. Appears the plasticity greatly.
