1. Development of Growth Control Technology for Producing High Quality of Chinese Cabbage in Alpine This study was performed to find out the optimum concentration of diniconazole on growth inhibition of Chinese cabbage for the summer production in the alpine region. Seeds of Chinese cabbage (cv. 'Kangruk Summer') were sown in 162 cells plug tray and seedlings of 25 days were transplanted in pots and field. For investigating the proper concentration of diniconazole (5% wettable power) in pot test, three different treatments (50, 100, 500 mgㆍ$L^{-1}$) were given. Higher dosages C100 and 500 mgㆍ$L^{-1}$) inhibited leaf growth and thus 50 mgㆍ$L^{-1}$ treatment was considered the optimum concentration. Numbers of leaf treated by diniconazole were increased (8-10 leaves) compared with the control. Diniconazole 50 mgㆍ$L^{-1}$ application reduced the head height up to 7 -10cm without influencing the quality and yield. Top fresh and dry weights were increased by diniconazole treatment at harvesting time, meaning improvement of growth. Glucose content was higher than frutose, especially showing higher content in lower part of leaves than higher part. The content of sucrose was undetected. Diniconazole application increased firmness and cutting force compared with the control. Residual contents of diniconazole soon after application were detected but not at 40 days after application. As a result, the proper amount of diniconazole (5% original sum) to regulate excessive growth of Chinese cabbage during summer season without decreasing marketable yield seemed to be 50 mgㆍ$L^{-1}$ with application frequency of 1-2 times at 20 days after transplanting. This study was carried out to obtain the effects of treatments of diniconazole(5% wettable power) on the characteristics of growth, especially, leaf-morphology and cell arrangement in chinese cabbage. "Garak" and "Duck-Sung" chineses cabbages were used. They were planted in the 162-cell of tray, for 25 days, then were transplanted the experimental pot(diameter: 17cm). The concentration of treated diniconazole were followed: 0, 100mgㆍL¹ and 1000mgㆍL¹. The methods of treatment were sprayed on all of the leaves of chineses cabbages; the first treatment was performed on the 5th of March in 2003. a week later, after transplantation. And the second was done on the 10th of March in 2003. 5 days later, after the first treatment was carried. In order to examine the cell arrangement, twenty randomly chosen cells per photographed section were measured for cell width and cell length. According to the results, the comparison of amounts of chlorophyll a, chlorophyll b among non-treatment and treatments of diniconazole was higher in treatment than those of non-treatment, by increasing the concentration of diniconazole. In comparing the cell width and length, the cell width of non -treatment was 42.8um and the length of non-treatment was 65.51um. On the other hand, those of treatment(100mgㆍ$L^{-1}$) and treatment(1000mgㆍ$L^{-1}$) of diniconazole were observed like this, width; 23.153um(100mg/L), 24.29um(1000mg/L) and length; 74.457um(100mgㆍ$L^{-1}$), 63.85um(1000mgㆍ$L^{-1}$). This study suggest that the treatment of diniconazole retards the growth of chinese cabbage and made their leaves more thicker, dark greener than those of non-treatemnt. Also, in comparison of cell arrangement among treatments and non-treatment, those of treatments(100mgㆍ$L^{-1}$, 1000mgㆍ$L^{-1}$) are more denser than that of non-treatment. Leaf blade of treatments of diniconazole showed loosely packed larger mesophyll cells and non-treated leaf showed tightly packed and smaller mesophyll cells.
