%X In this experiment, 4-year-old <em>Taxus chinensis</em> var. <em>mairei</em> seedlings were used as test material and treated with different concentrations (0, 0.01, 0.1, 0.5 and 1 mmol&middot;L<sup>-1</sup>) of sodium nitroprusside (SNP), a donor for exogenous nitric oxide (NO) to study the effect of exogenous nitric oxide on photosynthetic pigment and antioxidant enzymes in <em>T.chinensis</em> seedlings. The contents of photosynthetic pigment, malondialdehyde (MDA) and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), and the activities of antioxidant enzymes in <em>T.chinensis</em> seedlings were determined. Spraying low concentrations (0.01, 0.1 mmol&middot;L<sup>-1</sup>
