  • For improvement germination rate of Cirsium setidens, wet seeds were storaged for 20 to 80 days at $4^{\circ}C$ and germinated at $18^{\circ}C$ in the dark or light condition. To assess the effects of shading and plant age on the growth, fresh yield and seed yield under rain shelter in highland at altitude of 800m above sea level, seeds were sown in an open field in late september,1990. In early May the next the seedlings were transplanted for vegetatable and seed production in the plastic houses for rain shelter. They were grown from 1991 to 1993 in the houses covered with the shading nets ranging from 0 to 70% for vegetable production and 0 to 50% for seed production. Germination rate inceased as the storage period lengthened, and the rate came to $60\sim80%$ at 60days after germination. It was more effective in lighting than in darkness. For vegetable production, the shading net treatments showed more values in almost the characters checked at the third year than the non-shading treatment. No. of stem, no, of leaves, stem length and degree of softening were no different between shading net treatments, but the other characters were significantly different. Ratio of survival, density of chlorophyll and ratio of dry matter of plants were highest in the plots of 50%, 70%, and 30% of shading, respectively. The highest fresh yield was recorded from 2-year plants, 70% of shading from them showed the greatest yield. The highest seed yields were produced 2-year-old plants of non-shading plot. For seed production, the non-shading treatment is best, and the highest seed yields were obtained in both the second and third years.

  • This study was compared to outdoor field (OF) and rain shelter greenhouse (RSG) according to cultivation type of Gastrodia elata Blume. Also, the effects of yield and quality for mulching materials in RSG were compared. The yield of G. elata was investigated good merchantable quality, and the quality was investigated hardness, chromaticity, weight loss and the contents of the major functional components. The cultivation of RSG was increased the yield, hardness, gastrodin, and vanillyl alcohol compared to OF, and the weight loss, chromaticity, and ergothioneine were almost equal. Rice straw treatment showed higher than those of the control and other treatments on the yield and hardness. As a result, the yield and the quality of RSG, which can control the soil moisture, were better than that of OF. And the lower the soil moisture content according to the mulching material, the harder the surface and the higher the hardness.

  • This study was carried out to investigate the flower yield and quality of Lilium Oriental Hybrids as affected by planting date. In cut flower production experiments, effect of planting date and bulb source was studied in rain shelter houses with 30% shading. Four planting dates compared were May 15, June 5, June 25, and July 15. Bulbs used for cut flower production were either imported or produced domestically. The greatest cut flower yield and quality were obtained from bulbs planted either on May 15 or June 25. Bulbs planted on July 15 produced cut flowers of very poor quality and yield, due to high temperatures during the planting time. Therefore, for planting in July, means other than 30% shading have to be adapted to lower temperature during early growth stage. Although plants from imported bulbs had better growth and cut flower yield as compared to domestic bulbs, there was no significant difference.

  • This study was conducted to examine the characteristics of flowering and fruiting in Nelumbo pentapetala 'Yellow Bird'. Lotus rhizomes were planted in pot (70 cm in length and 71 cm in width) on April 18, 2008, and grown under rain shelter condition at a private farm in Muan-gun, Jeonnam. Ninety percent of the lotus plants were bloomed as two flowers per a plant, and the others were one flower. The first flowers were bloomed in the middle or late July, and the second flowers in the early August. Flower stalks were formed between eighth and tenth internodes in the main rhizome. Nelumbo pentapetala 'Yellow Bird' had light yellow flowers, 12 cm in length and 13 cm in width. Lotus plants of 21.4% were not bloomed, resulting from the insufficient securing of internodes in the main rhizome and the blind. We, therefore, concluded that Nelumbo pentapetala 'Yellow Bird' as a ornamental plant should be grown up to 8 in the node number of main rhizome until mid-July.

  • Various kinds of leaf spots and blights were found in kiwifruit (Actinidia deliciosa) orchards on 2006 in Korea. Disease incidences were quite variable between open-field and rain-proof shelter. Rate of diseased leaves was recorded as about 70% at open-field orchards in late season but use of rain-proof vinyl shelters alleviated the disease incidences by 20%. Angular leaf spots appeared at early infection stage on June and several other symptoms were also recognized as the disease developed afterward. On September, brown leaf blights were the most frequent, followed by grayish brown ring spots, silvering gray leaf blights, zonate leaf blights, dark brown ring spots and angular leaf spots at open-field orchards. Four fungal species were frequently isolated from the disease symptoms. Phomopsis sp. was the most predominant fungus associated with the leaf spot and blight symptoms on kiwifruit, followed by Glomerella cingulata, Alternaria alternata and Pestalo-tiopsis sp. Phomopsis sp. was commonly isolated from angular leaf spots, silvering gray leaf blights, and zonate brown leaf blights. G. cingulata, A. alternata and Pestalotiopsis sp. were isolated from grayish brown ring spots (anthracnose), brown ring spots and zonate dark brown leaf blights. Typical symptoms appeared on the wounded and unwounded leaves, which were inoculated by each of Phomopsis sp., G. cingulata, and Pestalotiopsis sp., but A. alternata caused symptoms only on the wounded leaves.

  • One of the abundant biomass for bioenergy production is thought to be agricultural by-products produced annually. The purpose of this study were to provide basic information about the changes of the moisture contents and chemical compositions for storage periods and bale types of rice straw, and it was attempted for the first time. The bale types of rice straw which were harvest in October 2011, were the square bale, the round bale, and the wrapped round bale type with plastic, respectively. Each of bale were stored in house, outdoor, and rain sheltering facilities condition for 1 year. The moisture contents and chemical compositions for each bale type are investigated for the 3-storage stages (0, 6, 12 month). While the moisture contents of the square and round bales stored in house condition were ranged from 20~25%, the square bale stored under the rain shelter facilities was showed the lowest moisture content less than 20% during the storage periods. For the chemical compositions, the cellulose and hemicellulose contents of rice straw bale stored in outdoor condition were decreased with the storage periods. However, in house condition, the chemical compositions of the square and round bales were slightly increased at the middle and the end of storage stages (6 and 12 months) compared with the initial storage stage (0 month). In conclusion, while optimum and favorable storage conditions of agricultural by-products is a house storage of the bale with plastic, if the bale can stored at outdoor, water penetration prevention such as the rain shelter facilities is required.
