Applied with test of potted plant and measurement absorbency for study physiological response of activity of cell defense enzymes and lipid peroxidation of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of superoxide dismutase, catalase, antioxidant, malondialdehyde and the rate of superoxide anion(-O2) generating are mensurated under normal water condition while soil water content is 70% and light water stress while soil water content is 55% to 60% and medium water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of contents of SOD,CAT,AsA,MDA are mighty notable difference. The rate of -O2 generating is notable difference within families. The rate of -O2 generating is mighty notable difference within water grades.
