Abstract
This study examines the growth and physiological characteristics of Hopea odorata growing under waterlogging
condition. H. odorata was selected as it is widely planted as urban landscape tree species which experienced some growth
stresses. Two waterlogging treatments and a control were designed. Forty 5-year old saplings each were subjected to
waterlogged condition for 30 days which were then allowed to recover for a further 30 days as Treatment 1 (T1) and
waterlogged condition for 60 days as Treatment 2 (T2). Aboveground and belowground biomass including leaf area was
determined before and at 30 and 60 days of study. The net photosynthesis (Anet), stomatal conductance (Gs), transpiration
rate per unit leaf area (EL) and leaf to air vapour pressure deficit (
