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.

研究了嫁接植株形成层的发育过程和接穗到砧木的水分运动。在嫁接过程完成之前，由于通过不完整的嫁接部分的高水分运输阻力，嫁接番茄中的水分运动明显缓慢。因此，嫁接不完善导致的茎中水分运动变化对嫁接番茄叶片光合产物的影响。在番茄与茄子、接穗与砧木嫁接的情况下，根据接穗与砧木茎粗的差异，嫁接不完善程度的增加，水运阻力变大。番茄叶片的茎粗和白度差异也呈显著正相关。因此，由于嫁接不完善导致水分输送阻力低，水分胁迫导致番茄叶片白度增加。
