통마늘의 규격 출하를 확대하기 위해서는 선별과 포장 작업의 기계화가 필수적으로 요구된다. 국내에서 통마늘의 선별은 대부분 수작업의 의존하고 있어서 작업능률이 매우 낮으며, 또한 작업자의 숙련도에 따라 선별의 정확도가 크게 좌우되고 있다. 특히 통마늘은 품종과 산지에 따라 모양이 다양하고 형상이 구형에서 크게 벗어나 있기 때문에 정확한 선별이 상대적으로 어렵다. 마늘 주산지를 중심으로 통마늘 선별기의 필요성에 대한 인식은 점차 확대되고 있으나, 기계의 개발과 보급은 매우 미흡한 실정이다. 일부 주산지에서 간격확장식 롤러를 이용한 과일 선별기를 통마늘 선별에 사용하고 있으며, 농촌진흥청 농업기계화연구소에서는 부채꼴봉식 통마늘 선별기를 개발한 바 있다(조 등, 2000).

This study was conducted to investigate the optimal sub-zero temperature for storage of two garlic cultivars, the northern ecotype 'Jaerae' and the southern ecotype 'Daeseo'. These cultivars of garlic bulbs were stored at different temperature (room temperature, $0^{\circ}C$, and $-4^{\circ}C$) conditions after predrying. Southern ecotype garlic showed higher weight loss than northern ecotype garlic. Northern ecotype garlic at $-4^{\circ}C$ exhibited less than 5% of weight loss during 10 month storage. Sprouting rate was higher in southern than in northern ecotype at room temperature storage. The value of injury by disease and insect was similar between southern ecotype and northern ecotype for 5 month storage, and then northern ecotype showed higher value of injury by disease and insect than southern ecotype. Hunter 'b' value of northern ecotype garlic was the lowest at $-4^{\circ}C$ storage. Northern ecotype garlic showed no cold injury at freezing point temperature storage. However, southern ecotype garlic had $0{\sim}5.3%$ cold injury occurrence at $-4^{\circ}C$ storage. Respiration and ethylene production exhibited the highest at room temperature storage, those had the slight increase at $0^{\circ}C$ and $-4^{\circ}C$ storages. Northern ecotype showed higher enzymatic pyruvic acid and fructan contents than those of southern ecotype. Enzymatic pyruvic acid content increased and fructan contents decreased during storage time.

This research surveyed the effect of endogenous gibberellins (GA), abscisic acid (ABA), jasmonic acid (JA) and sugar contents on bulb development and secondary growth in the southern type of garlic (Allium sativum L.) cv. Sangdongmaneul and cv. Namdomaneul of Korea. Sangdongmaneul and Namdomaneul showed endogenouse GA, ABA, JA and sugar contents were significantly different in patterns with different cultivar. GA and JA contents of southern type of garlic reached maximum before bulb differentiation and then their contents were decreased. On the other hand, ABA contents gradually increased from bulbing (leaf sheath: 6.58-18.59 $ng{\cdot}g^{-1}$ DW) start. GA contents in Sangdongmaneul and Namdomaneul were not significantly different from each other. These results revealed that GA contents were not affected by secondary growth of garlic. While JA contents (33.0-76.16 $ng{\cdot}g^{-1}$ DW) of Namdomaneul were higher than Sandongmaneul so our results suggest that JA suppressed development of secondary growth of garlic. Total sugar contents of Sandongmaneul and Namdomaneul were not significantly different but total sugar contents were gradually increased after bulb differentiation in Sandongmaneul and Namdomaneul.

Garlic and traditional fovarite foodstuffs of plant origin have been analyed for selenium and sulfur containing amino acid content selenium compound were assayed using a $^{77m}Se$ neutron activation analysis, cystine and methionine determination by paper and thin-layer chromatography. The results obtained indicate that the content of selenium and sulfur containing amino acid are highest in garlic. The results also show that the selenium is a more abundant in particular speies such as garlics produced in Tan Yang and Wei Sung. The effect of Korean garlic and favorite typically found in the Korean diet has also been studied. Some vegetables known to contain a relatively high level of sulfur and selenium (garlic and onion) do loss significent quantities of selenium as a result of cooking.

It was attempted to find a method to prevent greening of crushed garlic. The storage conditions and heat treatments before crushing were tested for the prevention of greening in crushed garlic. 'Namhae' garlic (sub-tropical type), 'Seosan' and 'Danyang' garlic (traditional) type for cool area) were stored in room temperature(20${\pm}5^{\circ}C$, low temperature(0$^{\circ}C$), and CA(O$_2\;3%,\;CO_2$ 5%) storage for five months, and their samples were crushed. The crushed garlic had no significant differences in greening according to the cultivars. Greening did not occur for the crushed garlic from bulbs stored either in room temperature or CA storage. Greening was the unique symptom observed in crushed garlic from bulbs stored in low temperature. For the prevention of greening, heat treatment was conducted at 40, 35 and 30$^{\circ}C$ prior to make the crushed garlic from bulbs which were stored in low temperature. The effective duration of heat treatment before crushing was 7 days at 30$^{\circ}C$, 3 days at 35$^{\circ}C$, and 1 days at 40$^{\circ}C$ Greening was most effectively prevented in 1 day at 40$^{\circ}C$ treatment. During the heat treatments, changes in enzymatic pyruvic acid content and sprouting rate were slightly observed in garlic bulbs treated at 40$^{\circ}C$ for 1 day.

This study was carried out to investigate characteristics of new garlic cultivar 'Alkae' and to identify the effect of scape removal on bulb characteristics and growth of garlic cultivar 'Alkae' and 'Namdo'. Bolting time and harvesting time were earlier about 20 days in 'Alkae' than those in 'Namdo'. 'Alkae' was inferior to 'Namdo' in top growth as plant height, number of leaves, leaf area, SPAD value, diameter of leaf sheath, and so on. but root developing was better in 'Alkae'. Bulb weight of' Alkae' was 17% more than that of 'Namdo', harvested on proper time. The ratio of bulb weight over 40 g was almost double in 'Namdo' as 48% with 'Alkae' as 25%. Occurrence of bulb cracking was more considerable in 'Alkae' and the number of clove per bulb was 1.9 more in 'Alkae' than 'Namdo', but the ratio of bulb rot during storage was higher in 'Namdo' than 'Alkae'. In treatments of scape removal, SPAD value did not show any difference between two cultivars. Leaf dryness was earlier and harder than control and leaf area showed the same tendency as leaf dryness, and there were no significant differences among the methods of scape removal. The bulb weight and the ratio of bulb weight over 40 g at 50 days after the harvest of 'Alkae', 'Namdo' were more 10%, 12% and 27%, 44% in scape removal treatment than control. and there were no significant differences among the methods of scape removal. So, scape removal was very effective to increase large bulb production in the two garlic cultivals and the effect was higher in 'Namdo' than 'Alkae'. The ratio of bulb cracking and the occurrence of bulb rot were almost same in with the scape removal and non removal groups And also there were no significant differences among the methods of scape removal.

Garlic (Allium sativum L.) is an important vegetable crop for the Korean people and has long been cultivated extensively in Korea. More recently it has gained importance as a source of certain pharmaceuticals. This additional use has also contributed to the increasing demand for Korean garlic. Garlic has been propagated vegetatively for a long time without control measures against virus diseases. As a result it is presumed that most of the garlic varieties in Korea may have degenerated. The production of virus-free plants offers the most feasible way to control the virus diseases of garlic. However, little is known about garlic viruses both domestically and in foreign countries. More basic information regarding garlic viruses is needed before a sound approach to the control of these diseases can be developed. Currently garlic mosaic disease is most prevalent in plantings throughout Korea and is considered to be the most important disease of garlic in Korea. Because of this importance, studies were initiated to isolate and characterize the garlic mosaic virus. Symptom expression in test plants, physical properties, purification, serological reaction and morphological characteristics of the garlic mosaic virus were determined. Results of these studies are summarized as follows. 1. Surveys made throughout the important garlic growing areas in Korea during 1970-1972 revealed that most of the garlic plants were heavily infected with mosaic disease. 2. A strain of garlic mosaic virus was obtained from infected garlic leaves and transmitted mechanically to Chenopodium amaranticolor by single lesion isolation technique. 3. The symptom expression of this garlic mosaic virus isolate was examined on 26 species of test plants. Among these, Chenopodium amaranticolor, C. quince, C. album and C. koreanse expressed chlorotic local lesions on inoculated leaves 11-12 days after mechanical inoculation with infective sap. The remaining 22 species showed no symptoms and no virus was recovered from them whet back-inoculated to C. amaranticolor. 4. Among the four species of Chtnopodium mentioned above, C. amaranticolor and C. quinoa appear to be the most suitable local lesion test plants for garlic mosaic virus. 5. Cloves and top·sets originating from mosaic infected garlic plants were $100\%$ infected with the same virus. Consequently the garlic mosaic virus is successively transmitted through infected cloves and top-sets. 6. Garlic mosaic virus was mechanically transmitted to C, amaranticolor when inoculations were made with infective sap of cloves and top-sets. 7. Physical properties of the garlic mosaic virus as determined by inoculation onto C. amaranticolor were as follows. Thermal inactivation point: $65-70^{\circ}C$, Dilution end poiut: $10^-2-10^-3$, Aging in vitro: 2 days. 8. Electron microscopic examination of the garlic mosaic virus revealed long rod shaped particles measuring 1200-1250mu. 9. Garlic mosaic virus was purified from leaf materials of C. amaranticolor by using two cycles of differential centrifugation followed by Sephadex gel filtration. 10. Garlic mosaic virus was successfully detected from infected garlic cloves and top-sets by a serological microprecipitin test. 11 Serological tests of 150 garlic cloves and 30 top-sets collected randomly from seperated plants throughout five different garlic growing regions in Korea revealed $100\%$ infection with garlic mosaic virus. Accordingly it is concluded that most of the garlic cloves and top-sets now being used for propagation in Korea are carriers of the garlic mosaic virus. 12. Serological studies revealed that the garlic mosaic virus is not related with potato viruses X, Y, S and M. 13. Because of the difficulty in securing mosaic virus-free garlic plants, direct inoculation with isolated virus to the garlic plants was not accomplished. Results of the present study, however, indicate that the virus isolate used here is the causal virus of the garlic mosaic disease in Korea.

Five local cultivars of northern type garlics (Allium sativum L.) and one of southern type were collected, and their growth and developmental characteristics and productivity were investigated to select a well adaptable cultivar in Euiseong region. Local cultivars used in this experiment were 'Euiseong', 'Yeochun', 'Danyang', 'Jungsun', and 'Yongin' as northern type and 'Namdo' as southern one. The growth characteristic of local garlic cultivars were differed with their ecotypes and 'Namdo', a southern type cultivar, showed higher growth rate at the early growing stage than northern types. However, no clear differences were observed among northern types. Incidence of bolting was low in 'Jungsun' and 'Yongin', while high in 'Euiseong' and 'Yeochun'. In the case of incomplete bolting, however, an opposite trend was showed, thus, high in 'Jungsun' and low in 'Euiseong' and 'Yeochun'. Secondary growth was remarkably low in 'Euiseong'. Considering yield factors, 'Yeochun' seemed to be most promising northern type cultivar in Euiseong region, which showed highest bulb weight and largest cloves with high growth rate at the maximum growing stage. 'Danyang', 'Jungsun', and 'Yongin' seemed to have relatively low productivity in Euiseong region.

작물은 각 지역의 기후 특성을 잘 반영하는 기후 경관 중의 하나이다. 작물의 분포는 농업기술의 발달정도, 작물의 수익성 등의 영향을 받지만 기후의 영향이 가장 크다. 그 지역의 기후 특성에 알맞은 작물을 심어야 생육이 활발하며 생산량도 증가한다. 반면에 기후 조건에 맞지 않은 작물을 재배할 경우 생육이 불량하며 수량성도 떨어진다. 그러므로 기후 환경은 지역마다 다양한 작물의 분포를 야기 시킨다. (중략)
