order to investigated the growth of tissue culture plants in 1 year-old `Kyoho’ grapevine (Vitis vinifera L.×Vitis labruscana Bailey), shoot tip tissue culture and cutting plants were grown in pot and the field of Viticulture Research Sta-tion, NCHU in summer of 1996, and their growth of shoots, leaves and roots were investigated in the period from spring to winter of 1997. Observing the sections of leaf, stem and root via microscope. It was found that the length and diameter of the shoot, length of the internode, number of leaves, fresh weight and dry weight of shoot, total area and weight of leaves of tissue culture plants were longer, larger and more than those of cutting plants. The fresh weight of shoot、leaves and root in tissue culture plant was 1.5 times greater than those of cutting plants. Tissue culture plants had dark green leaves, thickness leaves, high levels of cholorophyll, and high levels of photosynthetic rate. They also had delayed leaf-fall compared to the cutting plants. By observ-ing the sections of leaf, stem and root via microscope, it was shown that the array of cells was in good order and tight. Tissue culture plants were good than those of cutting plants.
