| 摘 要： | 对云南双江、龙陵、镇源、云县、石屏和墨江6个地理种源的钝叶黄檀在种荚长、宽、颜色、种子千粒质量、育苗发芽势、发芽率、幼苗苗高等指标的研究结果表明：不同地理种源的钝叶黄檀各项指标都有差异，同一地理种源的不同家系各项指标上也有明显的变异。不同地理种源的种子千粒质量、种荚内种子数量、种荚的宽度与种源地温度关系密切，与其它地理因素相关性不大。

| Abstract: | Through the study on the indexes of color, length and width of the legumens,seeds weight, germination potential, germination ratio, seedlings height of Dalbergia obtusifolia of different geographical provenances, the result showed that the above indexes was complicated and variational.Even in a same geographical provenance, different family's indexes were also different. The relation between provenance temperature and the indexes of weight,width of the legumens and seeds number of legumens were close. |
