广西6个箬叶竹地理种源形态特征及亲缘关系

为了解箬叶竹不同地理种源的形态差异，探讨其亲缘关系，将来自广西6个地方的箬叶竹引种至南宁市集中培育，成林后观察其形态特征以及出笋物候。结果发现，不同地理种源的箬叶竹之间存在着差异，其中贵港中里、金秀长垌的箬叶竹笋箨颜色均带有明显的紫色，出笋时间一致，形态相似；南丹山口、融水香粉、金秀忠良的箬叶竹的笋箨形态一致，均为绿色，略带紫色，亲缘关系较近；武鸣太平的箬叶竹箨鞘背面生疣基刺毛，形态相对独特，与其他5个种源有较大差别。

Morphological Characteristics of Six Geographical Provenances of Indocalamus longiauritus in Guangxi Zhuang Autonomous Region and Their Genetic Relationships

In order to understand the morphological differences of different geographical provenances of Indocalamus longiauritus and explore their genetic relationships,I.longiauritus was introduced from six places of Guangxi Zhuang Autonomous Region to Nanning City for cultivation,and their morphological characters and shooting phenology have been observed after the forests establishment.The results show that there are differences among various geographical provenances of I.longiauritus.The provenances from Guigang Zhongli and Jinxiu Changdong have the color of purple on their shoot sheaths,and their shooting time is the same and their morphology is similar;the provenances from Nandan Shankou,Rongshui Xiangfen and Jinxiu Zhongliang are the same in shape,green but with certain purple in color,and have close genetic relationship;the provenances from Wuming Taiping has verrucous bristles on the back of sheath,and are relatively unique in morphology,which is different from other 5 provenances.
