The comparison of leaf anatomical characters of 20 Eulaliopsis binata germplasm resources

Scanning electron microscopy was carried out to analyze the leaves of 20 Eulaliopsis binata germplasm resources. The results showed that there were significant differences in leaf length, leaf width, leaf area, leaf epidermis, leaf thickness, leaf stomatal density, leaf stomatal length, leaf stomatal width, leaf cell diameter, cell wall thickness, cavity diameter, and cavity wall ratio in leaf anatomical structure. Based on the cluster analysis of the cavity wall ratio as the important indicator of preferred paper material, the papermaking performance of tested E. binata germplasm resources will be categorized as the optimal, the good, the bad and the worst. The results can provide the basis for breeding and E. binata germplasm resources exploitation research in hilly area of southern China.
