Distributed dry our country in Yunnan, southern Guangxi and some countries in Southeast Asia, is a fast-growing timber species. 16-year-old tree up to 30 meters, diameter about 50 cm. Palm tree flowering March to May, fruit ripening May to July, each fruit contains 3-4 million seeds, seeds such as the tip of a small tip. In this paper, the physiological effects of light and temperature on the seed germination of Babao tree were initially reported. Materials and methods Babao tree seeds were collected from the vicinity, the first batch of seeds was collected in June 1978, known as the old seed; the second batch of seeds
