摘要:
为比较水青冈属两种植物间的叶片形态解剖特征和生态学适应性,采集了米仓山自然保护区26个分布地的台湾水青冈和米心水青冈,运用石蜡切片法将其成熟叶片制成切片,光学显微镜下观察叶片的结构特征,并测定叶片横切面的 5项数量性状指标。 结果表明:两种水青冈属植物叶片表型特征较一致，都表现出旱生植物的特征。测量指标的方差分析表明,主脉导管直径、栅栏组织厚度、木质部厚度3项指标在两种植物间差异均达到显著水平。台湾水青冈和米心水青冈种内居群间的主脉导管直径、上表皮厚度、栅栏组织厚度，海绵组织厚度，木质部厚度均有显著性差异，出现显著性差异的原因可能与海拔有关。
Abstract:
In order to compare the leaf anatomical characteristics of selected Fagus?species,two Fagus?species collected from 26 distribution in Micangshan nature reserve authority.Mature Leaves were cut into slices using paraffin sectioned.Leaf anatomical characteristics of Fagus engleriana?and Fagus hayatae were observed under optical microscopy.And 5 quantitative traits of leaf crosssection were measured.The results showed that leaf anatomy phenoty pictraits of the two plants were identical which all had obviously characteristics of drought resistance.Variance analysis of showed that there were significant differences between the two plants in thickness of palisade tissue,thickness of xylem in main vein and vessel diameter of main vein.All 5 quantitative traits of leaf crosssection between populations had significant differences respectively in F.engleriana?and F.hayatae.It speculated that the reasons might be associated with altitude.
