Abstract
The effect of light intensity and nitrogen form on growth and activities of antioxidative enzymes in leaves of tomato were studied. The results showed that the plant growth was not affected by nitrogen form under the low light intensity, but considerably inhibited by ammonium nutrition under the high light intensity. The <inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/1008-9209-2000-05-0500-I002.jpg"/> producing rate, H2O2 content, MDA content, activities of SOD, AsA-POD, DR and GR were significantly increased by ammonium nutrition under high light intensity, but not affected by ammonium nutrition under the low light intensity.
