Preliminary Study on Germination of Trigonobalanus doichangensis

Trigonobalanus doichangensis (A.Camus) Forman is the second-grade national protec- ted plant in China, and it is mainly distributed in Menglian, Lancang, Cangyuan, Ximeng and Mengla in Yunnan. Based on the data analysis of seed germination tests, the seeds germinated at 20℃-35℃. The deeper the seeds were placed in soil, the lower and slower were their germination. Under the condition of same constant temperature, germination rates of the light treatment (12 h/d) were higher than that of the dark treatment.,it seemed that the results were propitious to germination.
