Six species of rattan have been collected and planted at Chulabhorn Dam Agricultural Experiment Station, Faculty of Agriculture, Khon Kaen University. The comparative study on growth of rattan when planted in the area of natural forest condition and the area of open condition, showed that the growth of the rattan planted in the area of open condition was better than that planted in natural forest condition. But there was no difference on the number of tillers per clump. The rattan grown in natural condition had very slow growth rate. The preliminary study on the use of the different types of trellise for rattan in the area of open condition for one year showed no difference in plant height and number of tillers per clump. Also, the project has studied the technique in the propagation of this crop by the different methods, the result showed that there was no root by rattan cutting in the mist box, the separation of suckers gave the best result in May, June, July and August. Soaking seeds in the hot water at 60 deg C for 5 minutes gave the germination at 24 percent, whereas treatment with GA3 at 100 ppm, or seed grinding at 50 rpm gave the germination at 20 percent. Rattan has very slow elongation of the cane, normally spends 5-10 years of growing for suitable size for furniture. So the use of plant growth substance should be helpful to induce the growth and the sucking of tillers. BA (benzyl adinine) at the rates of 0, 100, 200, 300, 400, 500, and 600 ppm were applied 3 times at 30-day interval at the base of stem of 4-year old plants. The results showed no difference in number of tillers per clump.
