三棱栎种子萌发特性初探

Preliminary Study on Germination of Trigonobalanus doichangensis

  • 摘要: 三棱栎是国家二级保护植物,主要分布在云南省的孟连、澜沧、沧源、西盟和勐腊等地。通过对三棱栎种子萌发特性的研究表明,三棱栎种子的萌发温度在20℃~35℃范围内。种子在土壤中埋藏越深,其萌发越慢,萌发率越低。在相同的温度条件下,光照组(12h/d)的萌发率略高于黑暗组。说明光照有利于种子的萌发。

     

    Abstract: 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.
