Estimation of the Pigment Concentration in Seven Roadside Colonizing Plant Species at Three Different Suburban Areas of Jaipur District, Rajasthan, India: Variation in pigment concentration among roadside plants in suburban Jaipur

Abstract

Green plants synthesize chlorophyll and carotenoids that give color to the leaves and fruits, especially in the unripe stage. Chlorophyll content determines the photosynthetic capacity of the plant per unit area of leaf, stress, environmental pollution and nutritional deficiencies. In the present study the chlorophyll a, chlorophyll b and carotenoid was extracted from the leaves of seven roadside colonizing plant species growing in three different localities of Jaipur district of Rajasthan .Concentration of pigments was calculated using Arnon method. Both Chlorophyll a and Chlorophyll b content was higher in Datura stramonium and Carotenoid content in Tephrosia purpurea among all the other plant species studied.
