| 摘 要： | 通过对三棱栎的4个地理种源种子的大小变异特征、种子萌发和幼苗特征的初步研究。结果表明，种子大小存在着一定的地理变异，澜沧的种群种子最重最大，孟连的最轻最小。不同的地理种源种子萌发率差弄不显著。种子大小对幼苗高、生物量有明显的影响。

| Abstract: | The variation of seed sizes, seed germination and seedling characteristics were studied in Trigonobalanus doichangensis (A.Camus) Forman geographic populations of Menglian, Lancing, Cangyuan and Ximeng. The results showed that the variation of seed sizes is in different areas and the seed from Lancang is the largest and the seed from Menglian is the smallest, and that the seed germination was no significant either. The seed sizes have dominant effect on the seedling height and weight. |
