Nitrogen Nutrition Enhances Photosynthetic Pigment Synthesis in Crop Leaves: A Review

Research has shown that nitrogen nutrition plays an important role in regulating the synthesis of photosynthetic pigments in crop leaves (Peng et al.). N supply increases the photosynthetic apparatus along the sugarcane leaf by increasing chlorophyll content, the amount and activity of carboxylation enzymes, total protein, sugar content, total N and photosynthesis-related metabolites. The effect of nitrogen on the establishment of photosynthesis has also been reported in wheat.
