This study was carried out to determine the optimal conditions for the production of plants derived from the unpollinated ovary culture of Chinese chive (Allium tuberosum Rottl.). The Chinese chive collected from Korea showed much higher frequency of plantlet formation than those from Japan in the culture of unpollinated ovaries. Among the collections, 'Youngiljaerae' showed the highest frequency of plantlet formation. The MS basal medium was superior to B/sub 5/ in plantlet formation. The ovaries inoculated on the 2,4-D-free medium were directly induced plantlets without callus formation. Floral parts inoculated as a unit played important roles in callus formation and plant production. The frequency of callus and plantlet formation was higher in the culture of ovary with anthers than that of ovary alone.

Phytosterol contents in nine vegetables such as paprika (red, yellow, and orange), kohlrabi, bamboo shoot, cherry tomato, cucumber, Chinese chive, and corn were analyzed by gas chromatography. Individual contents of ${\beta}$-sitosterol, campesterol, and stigmasterol in fresh and cooked vegetables (boiling, grilling, stir-frying, deep-frying, steaming, roasting, and microwaving) were determined and compared. Total phytosterol content of paprika, cucumber, Chinese chive and cherry tomato ranged from 23.19 to 46.51 mg/kg (0.002-0.005%) of fresh weight of raw vegetables. Total phytosterol content variation (%) was obtained as follows: [(the content of phytosterol after cooking) - (the content of phytosterol before cooking)] / (the content of phytosterol before cooking) ${\times}100$. Total phytosterol content was found to be high in raw kohlrabi at 138.99 mg/kg fw (0.01%), in corn at 302.86 mg/kg fw (0.03%), and in bamboo shoot at 443.15 mg/kg fw (0.04 %). Total phytosterol content variation (%) in orange paprika ranged from 27.5 to 267.3 while that in cherry tomato ranged from -11.0 to 337.5. Generally, high content variation of total phytosterol was found in stir-fried and deep-fried vegetables. Therefore, higher phytosterol levels were obtained from cooked vegetables than raw vegetables. We suggest that these data will be useful to investigate cooking methods for increased intake of phytosterols.

Unusual mushrooms were observed in the greenhouses of vegetables Chinese chive, cucumber, melon and Korean dandelion in four locations of Korea in 2012. The mushrooms usually grew with the vegetables cultivated on beds in the greenhouses. Occurrence aspects of the mushrooms in the greenhouses and effect of the mushrooms on growth and quality of the vegetables were investigated. Mushroom samples were collected from the beds in the greenhouses and identified based on their morphological characteristics. The mushroom samples collected from the greenhouse of Chinese chive were identified as Coprinus aokii, those from the greenhouse of cucumber as Cristinia eichleri and Coprinus sp., those from the greenhouse of melon as Leucocoprinus cretaceous, Panaeolus fimicola and Conocybe sp., and those from the greenhouse of Korean dandelion as Conocybe rickenii f. tetrasporique. Out of the seven mushrooms identified, L. cretaceus, C. rickenii and C. eichleri were first found in Korea. The investigation results revealed that the mushrooms were originated from compost or soil used in the beds, and showed that C. aokii caused sooty mold on leaves of Chinese chive, and C. rickenii f. tetrasporique hindered growth of Korean dandelion and caused sooty mold on leaves of the plant. The other mushrooms had no effect on growth and quality of the vegetables.

Chemical compositions and texture of Allium senescens that is one of Korean indigenous culinary herbs were analyzed. The contents of carbohydrate and calorie were higher than those of Chinese chive. Proline, glutamine, valine, leucine and threonine were the major total amino acids in white and green portions of Allium senescens leaves. Methionine and cysteine were identified in white and green portions of Allium senescens leaves. The values of sodium and iron in Allium senescens were lower than in Chinese chive. Trace amount of selenium was also detected in Allium senescens leaves. The C$_{20:5}$ and C$_{20:6}$ were identified in leaves of Allium senescens. As a result of Rheometer analysis and sensory evaluation, texture of Allium senescens was more tender than that of green portion of Chinese chive leaves.

This study was evaluated the effect of attractant or repellent plants for establishing push-pull strategy for insect pest management of organic Chinese cabbage cultivation. The attractant or repellent effect of Ten plants, marigold, rye, Chinese chive, lettuce, chicory, Nongwoo-chicory, crown daisy, Treviso, green leaf mustard, and red leaf mustard were evaluated against diamondback moth, striped flea beetle, aphids, brown-winged stink bug and cabbage stink bug in organic Chinese cabbage field in Seosan in 2012. Of the ten repellent or attractant plants, rye and chicory attracted significantly brown-winged stink bug and cabbage stink bug, respectively. Aphids ate attracted significantly to the rye rather than the other plants. Leaf mustard was attracted cabbage stink bug and brown-winged stink bug in order. Cabbage stink bug was attracted by only a combination of lettuce and Chinese chive. Diamondback moth, striped flea beetle, aphid, brown-winged stink bug and cabbage stink bug were significantly repelled by single or combined cultivation of crown daisies, Treviso, and leaf mustard in organic Chinese cabbage cultivation. The results above-mentioned indicate that selected insect-attractant and -repellent plants can be used as tools for integrated pest managements of Chinese cabbage.

Biological control has many advantages as a disease control method, particularly when compared with pesticides. One of the most important benefits is that biological control is an environmental friendly method and does not introduce pollutants into the environment. Another great advantage of this method is its selectivity. Selectivity is the important factor regarding the balance of agricultural ecosystems because a great damage to non target species can lead to the restriction of natural enemies' populations. The objective of this research was to evaluate the effects of several different bacterial isolates on the efficacy of biological control of soil borne diseases. White rot caused by Sclerotium cepivorum was reported to be severe disease of garlic and chive. The antifungal bacteria Burkholderia pyrrocinia CAB08106-4 was tested in field bioassays for its ability to suppress white rot disease. In field tests, B. pyrrocinia CAB08106-4 isolates suppressed white rot in garlic and chive, with the average control efficacies of 69.6% and 58.9%, respectively. In addition, when a culture filtrate of B. pyrrocinia CAB08106-4 was sprayed onto wounded garlic bulbs after inoculation with a Penicillium hirstum spore suspension in a cold storage room ($-2^{\circ}C$), blue mold disease on garlic bulbs was suppressed, with a control efficacy of 79.2%. These results suggested that B. pyrrocinia CAB08106-4 isolates could be used as effective biological control agents against both soil-borne and post-harvest diseases of Liliaceae. Chinese cabbage clubroot caused by Plasmodiophora brassicae was found to be highly virulent in Chinese cabbage, turnips, and cabbage. In this study, the endophytic bacterium Flavobacterium hercynium EPB-C313, which was isolated from Chinese cabbage tissues, was investigated for its antimicrobial activity by inactivating resting spores and its control effects on clubroot disease using bioassays. The bacterial cells, culture solutions, and culture filtrates of F. hercynium EPB-C313 inactivated the resting spores of P. brassicae, with the control efficacies of 90.4%, 36.8%, and 26.0%, respectively. Complex treatments greatly enhanced the control efficacy by 63.7% in a field of 50% diseased plants by incorporating pellets containing organic matter and F. hercynium EPB-C313 in soil, drenching seedlings with a culture solution of F. hercynium EPB-C313, and drenching soil for 10 days after planting. Soft rot caused by Pectobacterium carotovorum subsp. carotovorum was reported to be severe disease to Chinese cabbage in spring seasons. The antifungal bacterium, Bacillus sp. CAB12243-2 suppresses the soft rot disease on Chinese cabbage with 73.0% control efficacy in greenhouse assay. This isolate will increase the utilization of rhizobacteria species as biocontrol agents against soft rot disease of vegetable crops. Sclerotinia rot caused by Sclerotinia sclerotiorum has been reported on lettuce during winter. An antifungal isolate of Pseudomonas corrugata CAB07024-3 was tested in field bioassays for its ability to suppress scleritinia rot. This antagonistic microorganism showed four-year average effects of 63.1% of the control in the same field. Furthermore, P. corrugata CAB07024-3 has a wide antifungal spectrum against plant pathogens, including Sclerotinia sclerotiorum, Sclerotium cepivorum, Botrytis cinerea, Colletotrichum gloeosporioides, Phytophotra capsici, and Pythium myriotylum.

The Korea chinese chives are a major edible vegetable and they are traditionally been used as a folk medicine. However recently studies on the Allium tuberosum are mainly on the morphological property and the chemical constituent. There are no reports concerning hematological changes in dogs administrated ethyl acetate extracts of Korea chinese chive. This experiment was conducted to investigate the hematological changes in dogs administrated ethyl acetate extracts of the Korea chinese chives($5m{\ell}/mg$) for 6 days. During administration blood samples were collected at 3h, 6h, 12h and then on daily basis until day 6. Blood samples were analyzed red blood cell(RBC), packed cell volume(PCV), hemoglobin concentration(Hb), mean corpuscular volume(MCV), mean corpuscularl hemoglobin concentration(MCHC), reduced glutathion(GSH), and met-hemoglobin concentration. The RBC count was significantly(p<0.01, p<0.05) decreased during experimental periods. Packed cell volume, hemoglobin concentration were not showed significantly difference during experimental periods. The MCV was significantly(p<0.01, p<0.05) increased from 3 hours after administration to day 4. The MCHC was significantly(p<0.05)decreased on day 6. GSH concentration was not showed significant difference during experimental periods and the met-hemoglobin concentration was significantly(p<0.05) increased on day 3.
