A Comparative Study on the Chlorophyll Content of Azadirachta indica Plantation Suffering from Automobile Pollution from the Meerut City, India

Abstract

In a comprehensive survey status in suffering leaves of Azadirachta indica in termsof green coloration and photosynthesis efficiency of plants around the various roadsof Meerut City, showed of significant change in chl a, chl b and total chl contentsand photosynthetic efficiency. The populations of autovehicles are significantlyincreases in crowded main road crossings of city connecting to Delhi,Muzzaffarnagar, Garh and Hapur. The chlorophylls and photosynthetic efficiencyof suffering leaves in hazardously smoke pollution level, significantly decreases witha yellow coloration. However, in a moderate level of air pollution level index areas(i.e., Collectorate, Roorkey Road and Medical College area), efficiency of chlorophyllcontents was slightly increases, as carbon dioxide level might indicated thephotosynthesis metabolism
