Seasonal Photosynthesis Variations of Dominant Tree Species Used in Different Urban Landscapes

Photosynthesis is the only natural process that converts photon energy into chemical energy, and it responsible for 90–95% of plant biomass accumulation hence growth. Environmental factors such as light, temperature, CO2 concentration in atmosphere are major influence photosynthesis, excess these can cause stress on plants. The photosynthetic response tree species found to vary factors. Therefore, be a good indicator assess environmental changing due urbanization used mitigate well by cultivating suitable species. present study provides information seasonal variations activity six In during month May (late summer early monsoon) most showed higher rates. It also noticed transpiration rate water use efficiency was more compared other months. An increase net photosynthesis observed among under high rainfall conditions 285.2 mm. decreased where evaporative demand very high.
