In this study, we analyzed and compared the constituents of Southern ecotype garlic cultivars, Namdo and Daeseo garlic, cultivated in volcanic and non-volcanic ash soil in Jeju Island and compared the soil properties in these regions. The volcanic ash soil in which Namdo garlic grew had higher electrical conductivity and more available sulfur, whereas the volcanic ash soil in which Daeseo garlic was cultivated had a higher amount of organic matter and total nitrogen. Also, non-volcanic ash soil in which Namdo garlic was cultivated had higher levels of available phosphorous. Namdo garlic cultivated in volcanic ash soil had high levels of total soluble solids and a high allicin content and Daeseo garlic exhibited a higher reducing sugar content. Furthermore, amongst the macroelements found in garlic grown on Jeju Island, potassium was highest, followed by sulfur, magnesium, calcium, and sodium. Iron was the most abundant micronutrient, followed by zinc, manganese, and copper. These results will be of interest to farmers aiming to cultivate high-quality garlic.

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.

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.

In this study, the quality characteristics of the representative domestic garlic varieties in Korea (Namdo, Daeseo, Hongsan, and Uiseong garlic) were compared and their changes according to the aging process of black garlic were investigated. Each garlic sample was aged for 15 days according to the manufacturing process of black garlic. The total phenolic compound contents were 85.2-109.7 mg GAE/100 g in raw garlic samples, which increased with the aging period, and Hongsan garlic showed the highest content in both raw and aged black garlic. The content of alliin was 848.3-1,087.5 mg/100 g in raw garlic samples, and it decreased significantly on the 5th day (7.3-20.6 mg/100 g) in aged garlic. The contents of GSAC (γ-glutamyl-S-allyl-cysteine) and GS1PC (γ-glutamyl-S-1-propenyl-l-cysteine) in raw garlic samples were 202.1-541.0 mg/100 g and 311.1-474.3 mg/100 g, respectively, but gradually decreased during the aging process. On the other hand, the SAC (S-allyl-cysteine) and S1PC (S-1-propenyll-cysteine) contents of raw garlic were very low in all four varieties, but they were highest on the 5th day of aging and tended to decrease thereafter. On the 5th day of aging, the SAC content of Namdo garlic (208.0 mg/100 g) was highest (p<0.05), and S1PC content was significantly higher in Uiseong garlic (66.2 mg/100 g) than the others.

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.

Antimicrobial activity of garlic extracts of four local cultivars (Namdo, Goheung, Danyang and garlic imported from China) against several plant pathogenic bacteria and fungi was investigated. The garlic extracts exhibited marked in vitro antimicrobial activities against the Gram-positive and -negative bacteria as well as fungal pathogens. Of the four cultivars, two cultivars (Namdo and garlic imported from China) showed relatively good antimicrobial activities. Gram-positive bacteria, Clavibater michiganensis was most sensitive, whereas Burkholderia cepacia was the strong resistant towards garlic extracts. Results from the planta bioassays under greenhouse conditions indicated that garlic extracts significantly reduced the cucumber powdery mildew disease showing control value 59.7-61.9% compared with the nontreated controls.

Occurrence of rust on 2 representative garlic cultivars Daeseo and N므애 in major cultivating regions of Goheung-gun, Jeonnam and Namhae-gun, Gyeongnam was investigated during 1998-1999. Rust disease severities of garlic ranging from 1.2 to 85.8 were quite different according to the investigating years and cultivars. Relatively high rust severities of garlic were observed in 1998 compared with 1999. This might be due to remarkably frequent rainfalls and high humidities during the growing seasons of garlic in 1998. Rust occurred severely on cultivar Daeseo but not on cultivar Namdo. This shows quite different susceptibility or resistance to rust among the cultivars of garlic. Increase of rust severities resulted in remarkable decrease in yields of garlic. It is assumed that rust might cause serious damages in the cultivation of garlic.

This study was conducted to evaluate cultivation to save the production method cost of warm type garlic. The optimum system for producing excellent seed bulbs by using bulbils of garlic has been required. The bigger size bulbils induced fast growth and lower rate of non-cloved bulbs. The ratio of non-cloved bulbs was the highest in the 0.1 g bulbils sowing of 'Namdo' and was low in the big size bulbils sowing. The bulbil growth rate of 'Deaseo' was much faster than that of 'Namdo', but most of 'Deaseo' bulbils showed low rate of non-cloved bulbs and small size scales in bulbs. The higher productivities of "Namdo" bulbils appeared at the September 11th sowing time, but 'Deaseo' bulbils produced small size non-cloved bulbs and got the very low ratio of non-cloved bulb production in all of the treatment, sowing that Jeju Island could not produce the non-cloved bulbs with 'Deaseo' garlic bulbuls. The growth rate such as leave number, leave length, bulb and clove size in the sowing distance of big size bulbils increased as the sowing distance was wider, but the rate of non-cloved bulbils decreased regardless of treatment. More than 3 g clove in the $10{\times}15cm$ distance of bulbs was produced resulted in sowing clove production potentials by using big size bulbil.
