Abstract: Acclimatization after grafting and graft-take that in order to produce plug seedlings of high-quality are important plug seedling stage which not reduce the plug seedlings quality before shipment.Appropriate acclimatization environment can not only increase seedling quality before secondary growth period, but also effective in promoting the growth of plug seedlings.This study was conducted to determine the optimal the shading period and shading level for acclimatization of tomato and pepper grafted plug seedlings after graft-take.The tomato and pepper seedlings were used in this experiment, and after graft-take, a tunnel was installed on a bed in glasshouse of venlo type to started shading treatment.The shading levels were 35, 55, 75 and 95%, and the shading periods were 1 and 2 weeks, and non-treatment was set as the control.In the case of tomato grafted plug seedling, plant height, stem diameter, dry weight of root, leaf area were significantly higher at the shading period of 1 week and the shading level was 55%.In the case of pepper grafted plug seedling, plant height, stem diameter, and leaf area were the highest in the shading period of 2 weeks and the shading level was 35%.However, dry weight of root, compactness, and T/R ratio, which seedling quality indicators, were lower than in the shading period of 1 week and the shading level 55%.Therefore, considering the quality of seedlings, it is suggested that shading period of 1 week with shading level of 55% treatment can be suitable to produce high quality grafted plug seedlings of tomato and pepper.
