| Research Abstract |
The process of development cambium layer of grafted plants and water movement from scion to stock was investigated. Before grafting process was completed, water movement in grafted tomates were significantly slow due to high water transport resistance through the incompleate grafted parts. Accordingly, influence of changes in water movement in stems due to imperfect grafting upon photosynthetic products in grafted tomato leaves. In case of grafting between tomato and eggplant, scion and stock respectivley, water transport resistance became large according to increase of degree of imperfect grafting that are indicated by difference of stem diameters of scion and stock. Difference of stem diameters and brix in tomato leaves were also positively correlated. Thus brix in tomato leaves increased by water stress caused by low water transport resistance due to imperfect grafting.
