Effects of Phosphorus Stress on Photosynthetic Pigments in Sagittaria sagittifolia

Abstract:

The photosynthetic pigments of Sagittaria sagittifolia, including total chlorophyll content, chlorophyll a content, chlorophyll b content and carotenoid content, were investigated after 0, 7, 14 and 21 d exposure to 3 mg L^-1 P. After 7 d P-exposure, total chlorophyll content, chlorophyll a content and chlorophyll b content increased significantly compared with the control, and then decreased with time extended. Carotenoid content increased significantly after 14 d P-exposure compared with the control, and then decreased slightly after 21 d P-exposure.
