ABSTRACT

 

The leaf area, photosynthetic pigment, leaf biomass and leaf area - dry weight ratio, (L/D ratio) of Cassia fistula were investigated in relation to auto- exhaust pollution. A significant reduction in the photosynthetic pigment content and leaf biomass was observed.
However Leaf area/dry weight ratio was increased in plants facing air pollution stress. Photosynthetic pigment content and leaf biomass was found to be positively correlated. The reduction in photosynthetic pigment and dry weight decreases with increase in distance from pollution source i.e. roadsides.

 

Keywords : Photosynthetic pigments, Leaf area/biomass ratio, Auto-exhaust pollution.
