| Research Abstract |
A field experiment to cause flowering induction was conducted in a tropical rainforest at Lambir Hills National Park, Sarawak, Malaysia. We established a big umbrella with 15m radius to prevent most rainfall to be received by the target tree root. The target trees made flowers by the experiment, and the method seems effective to cause artificial flowering induction. The changes in water potential of trees, sap flow, soil respiration, and fungal activities during the experiment were also monitored to discuss the effect of the artificial drought.
