Abstract
This study was carried out to understand the anatomical characteristics of Korean mistletoe (Viscum album var. coloratum) and host tree of Mongolian oak (Quercus mongolica) by the aid of light and scanning electron microscopy. The branch diameter of host tree at the parasitic part by mistletoe is larger than that of non-parasitic part. In the mistletoe, phloem consists of bast fiber and parenchyma cell and xylem is composed of fiber, ray and axial parenchyma cell, and vascular tracheid. The volume of ray parenchyma cell is higher than common wood species and is heterocellular made up of procumbent, upright, and square cells in the mistletoe. In the vascular tracheid of mistletoe, coarse spiral thickenings and bordered pit are present. Due to the insertion of the mistletoe haustorium, some deformed vessels but no tylosis are observed in the mistletoe. The shapes of mistletoe haustorium are sharp, and the destruction of the host tree cells due to the insertion of the mistletoe haustorium are not identified.
