| This study was conducted to examine the changes in growths of tomato and watermelon seedlings and the relationship among growth parameters which are used to evaluate healthy seedling as affected by shading. Plants were grown under 0%, 25%, 50%, and 75% shadings using polyethylene films. Leaf area index (LAI) of tomato and grafted watermelon seedlings increased under 50% and 75% shading. Total dry weight decreased with increase of shading level. The growth rates of stem diameter, LAI, total weight were faster under 50% and 75% shading with increase of integral radiation than under 0% and 25% shading. Stem diameters of tomato and grafted watermelon seedlings showed no significant differences among shading regimes. Stem diameters of tomato seedlings had upward tendency with increase of total dry weight and shoot height, but there were no significant differences among shading regimes. Stem diameters of grafted watermelon seedlings had no relationship with shoot height. These results indicate that stem diameter of tomato seedlings is not appropriate for assessing seedlings quality but stem diameter of grafted watermelon seedlings with shoot height is available. |
