Morphological and chemical components of Ulmus glabrar, Ulmus compestris, Zelkova carpinifolia, Celtis australis

The suitability of wood and noon-wood species for using in pulp and paper industry can be predicted by their morphological and chemical characteristics. In these research morphological and chemical properties of four spices of Ulmacea family, Ulmus glabrar, Ulmus compestris, Zelkova carpinifolia and...
