This research was conducted to figure out the optimal size of the plug cell and seedling raising period in 'Nongwoo' and 'Nonghyeop' cultivars. In the first experiment on effect of plug cell size on growth of squash, seedlings were transplanted into hydroponic cultivation beds at different growing stages: Those in 32-cell trays with 3-4 true leaves at 25 days after sowing, those in 50-cell trays with 2 true leaves at 15 days after sowing, those in 105-cell trays just before a true leaf development, and those in 162-cell trays with only cotyledons at 8 days after sowing. In the second experiment on effect of seedling raising period on growth of squash, it was conducted to have different sowing dates. But the same transplanting date, based on the results of Experiment 1, and compared the differences in growth and fruit productivity as affected by plug cell size in the same way with experiment 1 including the cultivars and environmental conditions. After setting the transplanting date in advance, the number of days for sowing were calculated back for each treatment. In the first experiment, plant height was the greatest in 105-cell trays followed by 162, 50 and 32-cell trays in both cultivars. The best fruit quality was found in different treatments depending on the cultivars, although it was the lowest in 32-cell trays in both cultivars. The fruit quality was not significantly different among those from cell sizes. Therefore, when raising seedlings in 105-cell trays, the period of raising seedlings can be shortened as compared with the conventional 32-cell trays, and this change could reduce the workforce required for growing and transplanting seedlings. In the second experiment, after transplanting, shoot height and leaf width in the first measurement in both cultivars were greater in the 32-cell treatment. However, the last measurement after four weeks showed no significant difference in plant height, but significantly greatest leaf width in the smallest cell treatment, even as compared with that in 32-cell treatment. In case of 'Nongwoo', length and weight of the first harvested fruit showed the highest values in the treatment of 105-cell trays. In case of 'Nonghyeop' the 162-cell treatment along with the 105-cell treatment showed greatest length and weight of the first fruits. From these results, zucchini plug seedlings can be raised in plug trays with reduced cell sizes than the conventional 32-cell trays with improved fruit productivity.

This study was performed to investigate the effect of various concentrations of Diniconazole (DC) on the growth and quality of grafted tomato (Solanum lycopersicum) seedlings cultivated during the summer season. Concentrations of DC were set to 0 (non-treatment), 5, 10 and 20 mg•L-1 , were treated once 3 days after grafting. Rootstock of the seedlings was shorter in the DC 5 mg•L-1 and 10 mg•L-1 treatment compared to the non-treatment, and the scions were significantly shorter in the DC 20 mg•L-1 treatment. Seedlings were significantly shorter in the DC 20 mg•L-1 treatment compared with the non-treatment. Leaf area was lower for seedlings subjected to all treatments than for seedlings in non-treatment group, and reduction was dose dependent. In particular, the DC 20 mg•L-1 treatment inhibited both leaf and stem growth. The fresh weighs of leaves and stems of the seedlings treated with DC 5 mg•L-1 and the fresh weights of roots subjected to all treatments were significantly greater than those of the non-treatment seedlings. Dry weight per organs of the seedlings treated with DC 5 mg•L-1 was significantly greater that of the non-treatment seedlings, but the dry weight of leaves of seedling treated with DC 20 mg•L-1 was much less than that of the non-treatment seedlings. The T/R ratio of the seedlings was lower for all treatments than for the non-treatment. The relative growth rate of the seedlings was significantly lower in the DC 20 mg•L-1 treatment and, the leaf area rate of seedlings was lower in the DC 5 mg•L-1 and 10 mg•L-1 treatment than in the non-treatment. Therefore, the optimal concentration of Dinoconazole used to produce a suitable grafted tomato seedling in the summer season is 10 mg•L-1 or less.

The objective of this study was to carry out the effect of seedling age on plant growth characteristics, photosynthetic rate, and the antioxidant enzyme activity of tomato(Lycopersicon esculentum Mill.) grown in a greenhouse. Forty-, forty-five-, fifty-, fifty-five, and sixty-day old seedlings from sowing to planting were planted in soil culture and grown in a greenhouse for ten weeks. Tomato growth and development of shorter seedling period less than 50-day old seedling was promoted, but plants with longer seedling period more than 50-day old seedling were decreased. At week 4, photosynthetic rates were lowest in 40-day old seedling age and there were no significant difference between treatments at week 8 after planting. Activities of antioxidant enzymes such as superoxide dismutase(SOD), catalase(CAT), ascorbate peroxidase(APX), and peroxidase(POX) were investigated. SOD activity was higher in 40-and 45-day old seedlings compared to other seedling ages at week 4 after planting. The highest CAT activity was investigated in 45-day old seedling at both 4 and 6 weeks after planting. At week 6 after planting, APX and POX was increased with increase of seedling ages from 50 to 60 days. Tomato yield was significantly increased with decreasing seedling age from 50-to 40-day old seedling ages. Hence it is considered that the optimum seedling age for tomato plant growth and yield was 40-to 50-day old seedlings. These results suggest that tomato plants with shorter seedling age less than 50-day old seedling promoted plant growth and productivity of tomato and then it would reduce production costs under soil culture.
