EVAPO-Transpiration and Transpiration Rate of Some Tropical Tree Species

Abstract

The present paper investigates transpiration and evapo- transpiration rate of tropical avenue tree species. The amount of water transpired per leaf was maximum in Azadirachta indica which was 2.88 followed by Eucalyptus camaldulensis 2.72 and minimum rate was found in Ficus religiosa i.e.1.48 gm/leaf/hrs. The rate of evapo-transpiration was also maximum in Eucalyptus camaldulensis followed by Azadirachta indica where is for other species they were relatively same. The present study confirms the reports that Eucalyptus.camaldulensis can transpire more than other Indian tree species but the study suggests that for cooling and shading purposes Eucalyptus camaldulensis is not a suitable tree. The lower rate of transpiration by Ficus benghalensis leaves is attributed to its xerophytes character. &nbsp
