Studies on net photosynthesis of young mangosteen plants grown under several growth conditions were carried out at Fruit Research Station, UPM, Serdang, Selangor. Mangosteen plants showed positive response to increasing carbon dioxide levels. However, increase in carbon dioxide did not indicate any saturation but stomatal conductance tend to increase with carbon dioxide levels. Light saturation occurred at 700 uE m-2s-1 where photosynthesis was at 1.81 mg CO2 dm-1 hr-1. Increase in light intensity after saturation did not result in any significant increase of photosynthesis. Flooding up to 72 hours did not kill the plants but photosynthesis was reduced significantly. Stomatal conductance was reduced when plants were under water for 24, 48 and 72 hours.
