PHENOLOGICAL ALTERATIONS AND BIOMASS REDUCTIONS IN TWO DECIDUOUS TREE SPECIES GROWING IN POLLUTED ENVIRONS

Jitendra G. Gavali, Deepa Saha, N.S.R. Krishnayya and S.J. Bedi

Abstract

Based on previous studies carried out on tree species growing in Baroda industrial area, Azadirachta indica (Juss.) and Holoptelea integrifolia (Planch.) were chosen to study the altered phenology and fluctuations in leaf and branch dry weight. Delay was observed in phenology and reduction in biomass was found by means of reduced leaf and branch dry weights of trees growing in industrial areas. Altered phenology and biomass reduction to trees were in correlation with wind direction, wind flow pattern and pollutant concentrations in the polluted environs.
