摘要
利用石蜡切片技术,用光学显微镜观测了5个品系橡胶树叶片的栅栏组织厚度、叶片厚度、主叶脉厚度等叶片解剖结构,并运用多重比较和隶属函数,综合分析其抗旱性。结果表明:5个品系橡胶树叶片角质层厚度、栅栏组织厚度、叶片厚度、主叶脉厚度等均有显著差异;根据隶属函数综合评价,5个品系橡胶树的抗旱性强弱依次为:保亭933>热垦525>RRIM513>海垦1>热研106。
In order to explore the relationship between leaf structure and drought resistance of rubber trees, leav- es rubber trees collected from 5 rubber clones （Hevea brasiliensis） were treated by using paraffin section tech- nique to observe their anatomical structures such as palisade tissue thickness, leaf thickness, main vein thick- ness, etc. under optical microscope. The data were subjected to multiple comparison and subordinate function a- nalysis to analyze the drought tolerance of the leaves of the 5 rubber clones. The results showed that there were significant difference among the 5 rubber clones in leaf cuticle thickness, palisade tissue thickness, thickness and main vein thickness. Muhiple comparison and subordinate function analysis showed the drought resistance of these 5 clones was in the order of Baoting 933 〉 Reken 525 〉 RRIM 513 〉 Haiken 1 〉 Reyan 106.
