| 摘 要： | 应用X射线（002）衍射的Cave法，对巴西橡胶树的13个具不同抗风力的品系PR107、海垦1、RRIM600、PB86、GT1等主干和枝干木材纤维壁的（微）纤丝角，进行了初步测试分析，结果表明：主和枝干木材纤维壁S2层的纤丝角，在抗风和弱抗风品系之间存在着明显的差异；品系的抗风力与木材纤维S2层纤丝角度有一定的关系，抗风品系的木材纤维壁S2层纤丝角度较小，弱抗风品系的纤丝角度较大；主干木材纤维S2层纤丝角度小于枝干材的纤丝角度。 |
| 关 键 词： | 巴西橡胶树 抗风性品系 胞壁纤丝角 木材结构 |

| Abstract: | The micro -fibril angles of the fiber walls were preliminarily measured using X-ray(002)diffraction Cave method in woods of13differently wind-resistant clones,i.e.PR107,HAIKEN1,RRIM600,PB86,GT1.and etc.The results showed that there existed significant differ-ences in the micro-fibril angle degrees in S 2 layers of fibril walls in trunk and branch woods between the wind-resistant and less wind-resistant clones.The micro-fibril angle degrees were rela tive to the wind-resistance of the clones to a certain extent.The wind-resistant clones were of smaller micro-fibril angles and the less wind-resistant cultivars were of larger ones.In addition,the micro-fibril angles of the trunk wood samples were smaller than those of the branch samples in the same clones. |
