| 摘 要： | 对广西境内的龙虎山、巴马、乐业三个蒜头果（Malania oleifera）自然分布区的蒜头果叶片进行解剖特征研究，探讨不同分布区蒜头果的叶片解剖特征及其表现出的生态适应性。结果表明，3个分布区蒜头果叶片在解剖结构上差异明显，但均表现出早生植物的特征。3个分布区中，巴马样地蒜头果表现出气孔密度较大、气孔较小而数目较多，角质层厚度较大，导管数目较多等特征，说明其具有更明显的生态适应性。

| Abstract: | The leaves of Malania oleifera were sampled in the natural fields of Longhushan,Bama,Leye of Guangxi,China. The results revealed that these leaves from three places were so difference in anatomy, but they were all characterized of xerophyte. Compared to other two places, the leaves of M. oleifera from Bama are thicker.in cuticle ,and have more stomas and vessels, but the stomas are smaller. It is showed that the individuals of M. oleifera in Bama have stronger adaptability. |
