Abstract: This paper deals with the effect of storage conditions on vigor of seed of Daemonorops margaritae (Hance) Becc. Seven levels of moisture content and two temperature treatments of each were conducted with coconut dust as storage material. The results showed that the seeds could be controlled in their safety moisture content (29%~31%) when they were stored in the material contained moisture content of 50%~65% at 15℃. In comparison with germination and moisture content of seeds, there were significant differences among the treatments; the seeds, stored in the material with moisture content of 55% and 65% at 15℃, could be able to keep their germination more than 65% for six months after storing, which were 4.0 and 4.5 times higher than that of seeds storing in the condition of room temperature (18°~25℃).
