  • A garlic (Allium sativum L.) is an important and useful vegetable such that it is not only most used for spices but also exploited for health foods and pharmaceuticals. The garlic is a kind of vegetable propagated vegetatively through cloves. Therefore, development of new varieties of garlics is possible only through selection breeding because cross breeding is impossible. (omitted)

  • The leaf segments of garlic (Allium sativum L.) were cultured in vitro and determined optimal concentration of plant growth regulators and sugars for callus induction, multiple shoots regeneration and in vitro bulblet formation. Highest yield of callus was observed in the leaf segment culture on Murashige and Skoog (MS) medium supplemented with 1.0 mg/L 2,4-D, 30 g/L sucrose and 8 g/L agar. Regeneration rate of multiple shoots from callus was high in the MS medium supplemented with kinetin 3.0 + NAA 3.0 mg/L or SA 1.0 + NAA 3.0 mg/L, containing 30 g/L sucrose. High rate of bulblet formation was observed as the concentration of jasmonic acid increased from 0.5 to 2.0 mg/L in medium, whereas addition of gibberellic acid significantly suppressed bulblet formation. The rate of in vitro bulbing was as high as $96\%$ in MS medium supplemented with 2.0 mg/L jasmonic acid and 120 g/l sucrose after two month culture at $25{\pm}1^{\circ}C$ under 16 hours day light.

  • White Muscardine is the most common fungal disease of silkworm, Bombyx mori L. caused by the pathogenic fungus, Beauveria bassiana (Balsamo) Vuillemin. In the present investigation, an attempt has been made to screen locally available medicinal/ weed plants against Beauveria bassiana. Among the plant extracts (PE) tested, 5% aqueous crude extract of the bulb of Allium sativum (Garlic) has been found to be most effective against Beauveria bassiana. The radial growth of Beauveria bassiana in vitro was inhibited to the tune of 54.9% in aqueous extract and 54.4% in ethanolic extract of Allium sativum and correspondingly mycelial dry weight gave rise to 110.7 mg and 108.7 mg against 201.7 mg in control 15 days post treatment. Similarly, silkworm larvae topically inoculated with the Beauveria bassiana conidia ($1.8{\times}10^6/ml$) registered survival up to 53.0% against 0.0% in control after treatment with aqueous extract of Allium sativum. Simultaneously, as a preventive measure, silkworm larvae were put to rear in conidia contaminated seat paper instantly treated with aqueous extract of Allium sativum that also increased survival up to 61.0% against 4.6% in control. It is also observed that the plant extract is absolutely innocuous to silkworm.

  • Gartic bulblets were planted to investigate the effect of some different cultivating conditions on the growth and bulb formation of the garlic plants (Allium sativum L.) Two different conditions namely perfect and imperect aerobic condition, and 3 different fertilizer levels was made. The split plot design was adopted for this experiment. 1) For the growth rate, under the imperfect aerobic condition, the plant height was more increased than that of perfect aerobic condition no relation to the fertilizer levels. 2) With respect to the fresh weight of garlic, the similar tendency to the growth rate was observed, but dry weight was did not. 3) The uptake of phosphorus was found to be increased in the imperfect condition. It could there be concluded that imperfect aerobic condition seems to be much favorable condition than the perfect aerobic condition to the development of garlic bulbs.

  • We have studied the DNA of Allium sativum L. with respect to highly repetitive sequences. Fast reassociated DNA fragments expected to be highly repetitive sequences based on $C_{o}t$ curve were isolated and characterized. Their copy numbers were approximately $10^{5}~10^{7}$ per haploid genome. Nucleotide sequences analysis of six candidates reveals that their G/C content were low, 25-40% and typical patterns of repeating sequences exist. Repeat sequences were used as probes to access restriction fragment length polymorphism (RFLP) of genomic DNAs of four local clones, Tanyang, Mungyong, So san, and Uisong. The hybridization pattern were very similar among these four local clones.clones.

  • Garlic (Allium sativum L.) is one of the most important vegetables used in various foods in Korea and many countries. The growth of garlic is influenced by various abiotic factors such as cultivation temperature, humidity, minimum temperature duration, and photoperiod. This study investigated the effects of increasing temperatures on the plant growth of the northern- ecotype garlic 'Uiseong' in a temperature gradient tunnel. As a result, temperature increase led to decreases in the bulb diameter, weight, and clove pieces of garlic. The rise of cultivation temperature increased the occurrence rate of incomplete bolting in the Northern-ecotype garlic 'Uiseong', resulting in decreases in productivity and a decrease in the yield of marketable garlic, indicating that temperature increases affect the development of garlic bulb formation. The findings of this study are expected to contribute as foundational data for understanding the growth responses of the northern-ecotype 'Uiseong' to increasing cultivation temperatures. The results of this study can be used to develop designing garlic growth models. In addition, the results of this study can improve understanding the interaction between increased temperature and garlic growth.

  • Calli obtained from a shoot-tip of garlic, Allium sntivum L., were encapsulated using a calcium alginate gel. Some of the encapsulated calli were cultured on a 1/2 MS medium supplemented with 3% sucrose, 10$\^$-5/ kinetin, and 5 ${\times}$ 10$\^$-6/ M NAA whereas the remainder was stored for 40 days at 4$^{\circ}C$. All the naked calli regenerated on the solid medium, while 95% of the encapsulated calli regenerated, and 88% of the encapsulated calli regenerated after 40 days of storage at 4$^{\circ}C$. The capsule matrix delayed the germination time of the encapsulated calli, yet activated the shoot formation of the artificial garlic seeds. The shoot length of the encapsulated garlic calli was much longer than that of the naked garlic calli. The encapsulated garlic calli were dried in a laminar airflow cabinet and the conversion frequency of the dried artificial garlic seeds on a 1/2 MS medium remained at 93% with a water Loss of Less than 50%.

  • Multiple shoots of garlic (Allium sativum L.) were propagated in bioreactors containing MS medium supplemented with 2% sucrose for 3 weeks. Microbulbs were induced on MS medium supplemented with 0.1mg/L NAA and 11% sucrose for 9 weeks. For multiple shoot proliferation, leaves in the shoot must be removed before cultures. When the multiple shoots were cultured without removal of leaves, more than 90% of hyperhydricity and no microbulb formation were observed. Histological observation also indicated irregular size and shape of the cells in hyperhydricity of the shoot. Microbulbs were strarted to form from the shoot after 7 weeks of culture by protuberance of adventitious shoot buds followed by inner periclinal divisions and simultaneous anticlinical division in the epidermis of meristematic bulge. Analysis of ploidy level indicated no phenotypic variations in both multiple shoots and microbulbs induced from the mother plant, suggesting genetic homogeneity among the regenerants.

  • This study was conducted to clarify of relationship with major physiological characters and RAPD patterns of garlic(Allium sativum L.) germplasm collected from the worldwide using randomly amplified polymorphic DNA(RAPD) analysis. Eighty-four garlic accessions were classified into ten varietal groups by physiological characters with the single linkage clustering based on Q correlations. The majority was early maturing varieties collected from East-Asia, late maturing varieties were Europe. RAPD marker, $WE61_{1,630}$ was amplified with late maturing varieties and high correlation have shown, though three accessions weren't amplified. Clove undifferentiation and secondary growth had mainly occur accessions collected from Europe, but hadn't shown perfect linkage to RAPD. RAPD marker, $WF70_{1,400}$ appeared in bolting garlic and $WF64_{1,400}$ appeared only in fertile garlic. Unknown garlic amplified in $WF64_{1,400}$ might be fertile garlic, because of their collection site were from Central-Asia.
