Plant internode of poinsettia seeding is longer than that of cutting and the seedlings are vigor and grown faster. Taking these advantages of seedlings for tree poinsettia production could reduce the labor cost of axillaries or leaf removal on the trunk. The emergence percentage of poinsettia seeds is 64.0%before grading the seeds to large (>5.0 mm), medium (4.75-5.0 mm) and small (<4.75mm), the emergence percentage of large seed could be improved to 71.0%. Seeds emergence at 25℃ could be improved than 80%, but the germination percentage and cotyledon opening percentage will decrease when sowing temperature is excess 28℃,as well as was only 30% when seeds sowing at 34℃. Consequently, 28℃ is the maximum temperature that appropriate for poinsettia seeds sowing.
