Green plants synthesize a wide range of primary and secondary metabolites in different quantity. Chlorophylls belong to the primary metabolites that give the color of the leaves and fruits, especially in the unripe stage. The spectral properties of chlorophylls are essential in harvesting light energy and in the transduction of absorbed light energy for photosynthesis. Like other plants, the variation of leaf colour, as well as photosynthetic activity in Citrus species, is dependent on chlorophyll concentration. Chlorophyll content determines the photosynthetic capacity of the plant per unit area of leaf, stress and nutritional deficiencies. The study of chlorophyll content in seven Citrus species growing in different localities of Kokrajhar district of Assam has shown some variability among them as an individual character.
