Responses of Sagittaria sagittifolia to Nitrogen Stress in Terms of Photosynthetic Pigments

Abstract:

Sagittaria sagittifolia was grown in nitrogen (N) stress monoculture to test the relative content of three pigments by the manipulative indoor experiment. The treatment consisted of one level of N (14 mg L^-1 N) of nutrient solution. The content changes of three pigments were studied in continuous 21days. Results showed that the content of pigments was significantly increased at the first 7 days. With N stress increasing in the medium, the content of pigments decreased slowly. After 21 d N-exposure, the content of pigments were still higher compared to the contol.
