  • Purpose: To provide the public with nutritional information on consumption types of garlic, we evaluated the influence of heat treatment method on the nutritional contents of different species of garlic. Methods: We determined the content of general components, minerals, vitamins, and fatty acids in each species of garlic produced in Seosan and Goheung by heating with blanching or microwave roasting. Results: The results of the two-way analysis of variance test indicated that the species in particular, as well as method of heat treatment and interaction, had an influence on nutritional content. The moisture and crude fat content was higher in Southern type garlic than in Northern type garlic, while crude proteins, crude ash, and dietary fibers were more abundant in Northern type garlic than in Southern type garlic. With regard to the total mineral content, K, P, Mg, and Ca were the main components in Northern type garlic and Southern type garlic. Moreover, unsaturated fatty acids showed high levels in both Northern type garlic and Southern type garlic, with more abundant linoleic acid. Overall, Northern type garlic showed a higher content of minerals and fatty acids, while more vitamin B was present in Southern type garlic. In addition, the results indicated that the content of general components (dietary fiber excluded) was increased in both Northern type garlic and Southern type garlic upon heat treatment. Blanching resulted in increased mineral and fatty acid content in Southern type garlic and decreased content in Northern type garlic, indicative of species differences; conversely, microwave roasting contributed to an increase in the content in both Northern type garlic and Southern type garlic. Conclusion: The nutritional content of garlic is more dependent on species than the cooking method, and grilling is associated with less nutrient loss than blanching.

  • This study carried out farmland suitability analysis for southern-type garlic cultivation considering soil and temperature as well as water deficit conditions. The spatial extent was limited within the area derived by Kim et al. (2012) using just soil and temperature constraints. Daily soil moisture was simulated using a one-layer soil water balance model at a $100{\times}100m$ grid unit, and then annual water deficit was calculated from 2000 to 2010. The farmland suitability was classified as four steps: best suitable, suitable, possible, and low productive. As a result, total area of best suitable or suitable farmland was about 375,900 ha, and Gimje-si and Haenam-gun were appeared as the largest favorable area for southern-type garlic cultivation. The best suitable or suitable area at Haenam-gun, Goheung-gun, Shinan-gun, Namhae-gun, and Muan-gun, major production regions of southern-type garlic, were extracted as 20,187 ha, 13,018 ha, 4,715 ha, 1,319 ha, and 349 ha, respectively. On the other hand, the result showed that the adoption of sprinkler irrigation systems might be critical in cultivating the southern-type garlic at some regions having poor water balance.

  • We developed a simple model to predict emergence time and emergence rate of southern type garlic using the daily mean temperature. Emergence rate of garlic was decreased and emergence time was delayed on higher temperature than optimum temperature of $12.7^{\circ}C$. In the model, firstly daily emergence rate was calculated using a beta function to input daily mean temperature, then the percentage of garlic emergence was calculated using a nonlinear model with accumulated emergence rate. The model was good to describe the experimental data of growth cabinet. Also it can explain well the experimental data using temperature gradient tunnel, designed for verification of model performance. But there are 5 days of deviation between estimated and measured time of garlic emergence on the field experiment. More research is needed to develop an advanced model considering other factors, such as soil moisture.

  • Global warming brings about changes of diverse environmental, especially changes of plant distribution. The purpose of this paper is to examine the relationship between temperature rise and changes of northern limit of vegetation growth in Korea. Bamboos (Phyllostachys) and boundary between the northern type and southern type of garlic (Allium sativum L.) were selected. The data of the distributions of bamboos and garlic are collected by field survey and interviews. Temperature is analyzed from 1904 to 2000. The northern limit of Phyllostachys moves 60-100 km northward, for about 100 years, the period of 1907-2003 and mean temperature of Korea increases about $2^{\circ}C$ during the same period. It means that the northern limit moves 30-50 km northward, for each $1^{\circ}C$ rising of January mean temperature. The boundary between the northern type and southern types of garlic moves northward 40-140 km from 1980s to 2000. The moving width is broad in the west coastal region while the width is narrow in the inland and mountain regions. The mean moving width is about 100 km.

  • This study was carried out to evaluate the land suitability for southern-type garlic cultivation associated with both temperature and soil constraints. The suitability analysis was conducted with hourly temperature data from 2001 to 2010 at all fifty seven meteorological stations and the soil-based suitability map of garlic provided by Rural Development Administration. Firstly the temperature data were processed by the growth stages (germinating, bulbing, and winter vegetation season), and then were adopted to limit the irrelevant lands. Next, as a result of overlaying each soil and temperature suitability map, the total 274,339 ha of area was mapped as highly suitable or suitable for southern-type garlic cultivation and the top four of the largest classified si-guns were identified as Naju, Jeongeup, Gochang, and Jinju. On the other hand, the statistical records of KOSIS (KOrea Statistical Information Service) showed lower amount of cultivation area than the analyzed results in the major production sites, Goheung, Sinan, Haenam, and Muan. However, it should not be regarded as exceptional because farmer's preference might not correspond to potential land usability.

  • Garlic is one of the most popular seasoning bulb vegetables in Korea and is the most commonly used food ingredient. However, the cultivation areas are decreasing every year as the price drops due to imported garlic, and labor is insufficient to produce garlic by conventional methods. Cultivation requires various tasks until garlic is harvested. Seeding is one of the important and laborious tasks; thus, mechanization is necessary. When seeding garlic, the sprout should face upwards; otherwise, it may rot or produce poor quality garlic. This study investigated the extent of growth of northern- and southern-type garlic in eight different positions. The results show when the roots were not planted properly, the stems were weak, and the garlic bulbs were small. A simple garlic planter was manufactured with a crank-press mechanism to plant garlic in an upright position. Using this machine, a three-fold experiment was carried out with 100 strips of garlic. The test results showed that 99.4% of the planted garlic strips were positioned upright or close to being upright, and 0.6% failed to take root. An image processing algorithm was developed to locate the root part of the garlic, and the result showed a success rate of 81%. A future study will develop an automatic garlic upright planting system with a viewing system.

  • 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.

  • This study was conducted to blow the effect of postharvest physiological changes on garlic quality according to its ecotypes and storage temperatures. The changes of water, total soluble solids, crude stein, md total fructans were measured and the rates of respiration and sprouting were analyzed during storage at 20$^{\circ}C$ and 30$^{\circ}C$. The decrease of water content and the increase of total soluble solids were reversely appeared during garlic storage. The crude protein content was gradually increased during storage but total fructan content was decrased. The respiration late was maximized at 60days after storage and the spouting rate was gradually increased. In the aspect of ecotypic characteristics, the water content, fructan content and sprouting rate were higher in 'Namdo' cultivar than those of southern type. The high storage temperature (30$^{\circ}C$) controlled spouting and loss of fructan, and it was effective to maintain the garlic quality.

  • 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.

  • This study was carried to survey distribution of the nucleotide polymorphisms in heme-binding (HB) domain, which is highly conserved region between 1,210 and 1,240 bp of cytochrome P450, in domestic garlic cultivars. 120 garlic cultivars collected from Korea were classified into seven HB domain variation based on the nucleotide sequence of the domain. Northern type garlic cultivars, collected from Kyungpook, Chungnam, Chungpook and Kangwon province, showed 51.3% of KP2 type nucleotide sequence, 5'-TTT/GGC/GGT/GGA/CGG/AGA/ATA/TGT/CCT/GGA-3' with coding amino acid FGGGRRICPG, 13.7% of KP1, 11.3% of CP, 8.8% of CM and 5% of KW2 types. Southern type cultivars, collected from Kyungnam province, showed 52.5% of KM type nucleotide sequence, 5'-TTT/GGC/GCA/GGA/CGG/AGA/ATT/TGT/CCT/GGA-3' with coding amino acid FGAGRRICPG, 22.5% of KP2, 5.0% of KW2 and 2,5% of CP type nucleotide sequence. These results showed that Korean garlics were cultivated in highly mixed condition even in the same region.
