The present study was conducted to investigate growth performance and ascorbic acid contents of Allium victorialis var. platyphyllum, Ligularia fischeri, and L. stenocephala growing under four different light intensity regimes (full sun, and 64~73%, 35~42%, 9~16% of full sun). The leaf area and total biomass of Allium victorialis var. platyphyllum were highest in 35~42% of the full sun. However, the leaf area and total biomass were highest in 64~73% of the full sun in Ligularia fischeri, and L. stenocephala. The leaf thickness decreased with increasing shading in all three wild vegetables. The growth of root comparing to that of shoot decreased as shading increased, and as the result, the ratio of shoot biomass to root biomass increased. Ascorbic acid contents were higher in Allium victorialis var. platyphyllum than in Ligularia fischeri and L. stenocephala. Allium victorialis var. platyphyllum showed the highest contents of ascorbic acid in 35~42% of full sun. Whereas Ligularia fischeri and L. stenocephala showed the highest in 64~73% of full sun.

This study evaluated the effect of Allium hookeri roots on lipid metabolism of the serum, liver, and adipose tissues induced by a high-fat diet in male Sprague-Dawley rats. The rats were divided into four groups with 8 rats per group for 4 weeks: the normal-diet group (N), the high-fat diet (HFD) group, the HFD containing 3% Allium hookeri (HFD-A3) group, and the HFD containing 5% Allium hookeri (HFD-A5) group. The results showed that the body weight gain and food intake of rats in the HFC-A3 and HFC-A5 groups were significantly decreased compared with those in the HFD group. The epididymal adipose tissue weight in the HFD-A5 group was significantly decreased compared with those in the HFD group, and adipose tissue weights of liver and mesenteric adipose tissues in the HFD-A3 and HFD-A5 groups were significantly decreased compared with those in the HFD group. Serum triglyceride, total cholesterol and LDL cholesterol concentrations, atherogenic index, and cardiac risk factor were significantly lower in the HFD-A3 and HFD-A5 groups than in the HFD group. Serum lipid profiles, as well as ALT and AST activities did not show any difference in all groups. Serum ALP and LDH activities were suppressed in the HFD-A5 group compared with those in the HFD group. The hepatic triglyceride and total cholesterol levels of rats in the HFD-A5 group was significantly lower than those in the HFD group. Moreover, triglyceride and total cholesterol in the epididymal and mesenteric adipose tissues were significantly lower in the HFD-A5 group than in the HFD group. These results demonstrated that the intake of Allium hookeri showed a hypolipidemic effect, changing the lipid metabolsim of a high-fat diet induced rats.

The present study was aimed to investigate whether ethanol-extract of Allium wageki has an ameliorative effect on the renal function in high fructose-diet induced hypertensive rats .. The urine osmolality (Uosmol) was decreased in rats with high fructose-diet (60%) during the whole experiment period without change of the urine volume (UV). The urinary excretion of sodium (UNaV) and chloride (UCIV) were decrease significantly in rats with fructose-induced hypertensive rats, whereas urinary excretion of potassium (UKV) was Increased. The creatinine clearance (Ccr) and solute-free water reabsorption were also decreased by treatment of fructose-rich diet. Among these renal functional parameters, Ccr was partially restored by the administration of ethanol-extract of Allium wageki. The Uosmol was also partially restored by the administration ethanol-extract of Allium wageki at the end of the experimental period. Taken together, ethanol-extract of Allium wageki has the ameliorative effect on glomerular filtration rate in rats with high fructose-diet induced hypertension.

Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa accession 'CBT-Ac77' and cultivar 'Arka Kalyan' were observed to be highly resistant. In vitro inoculation of a selected set of genotypes with A. porri, revealed that 7 days after inoculation was suitable to observe the disease severity. In vitro screening of 43 genotypes for resistance to A. porri revealed two resistant lines. An additional 14 genotypes showed consistent moderate resistance in the field as well as in vitro evaluations. Among the related Allium species, A. schoenoprasum and A. roylei showed the least disease index and can be used for interspecific hybridization with cultivated onion. Differential reaction analysis of three A. porri isolates (Apo-Chiplima, Apn-Nasik, Apg-Guntur) in 43 genotypes revealed significant variation among the evaluated Allium species (P = 0.001). All together, the present study suggest that, the newly identified resistance sources can be used as potential donors for ongoing purple blotch resistance breeding program in India.

This study aims to determine the difference in profitability of Allium victorialis farming system between on-field and under-forest, and to propose several better ways for development of under-forest farming system of Allium victorialis. Survey was conducted 12 farmer in Gangwon, Chungnam, Jeonnam, Gyeongbuk to investigate production cost, management cost, input labors and so on. In this study, IRR, B/C ratio and NPV were used for profitability analysis. The result applied 25,000 won for under-forest farming system and 15,000 won for on-field farming system as unit price of sale showed IRR 36.2% and 54.2% respectively. The profitability of Allium victorialis from under-forest farm was not lower than other non timber forest products. And it will be possible to create high profitability such like that of Allium victorialis from on-field farm, providing the technical development for intensive farming is supported.

Biological compounds such as crude saponin and total polyphenol were determined in Allium hookeri roots and leaves. In addition, activities of DPPH radical scavenging activity, hydroxyl radical scavenging activity, ${\alpha}$-amylase inhibition activity and nitrite scavenging were detected in concentrates of 70% ethanol extracts of Allium hookeri roots and leaves. The crude saponin content of the roots and leaves were 4.28 mg/g, and 4.17 mg/g, respectively. Total polyphenol and total flavonoid content was higher in leaves than roots. Furthermore the DPPH radical scavenging activity and hydroxyl radical scavenging activities of leaves was higher than roots. For ${\alpha}$-glucosidase inhibitory activity, 70% ethanol extracts of Allium hookeri roots and leaves showed 60% activity inhibition at a 10 mg/mL concentration. Nitrite scavenging abilities under acidic conditions were most effective for Allium hookeri leaves extracts. These results suggested that Allium hookeri leaves might be used as the components of health functional food.

Polyploidization plays an important role in generating the current high diversity of plants. Studies of the distributional patterns of diploid and derivative polyploid races have provided important insights into the evolutionary process and cryptic speciation by polyploidization within and between closely related taxa defined on the basis of their morphology. Allium thunbergii and A. sacculiferum, occurring throughout eastern Russia, eastern China, Korea, and Japan, are examples of closely related species with unsolved taxonomic relationships. A total of 97 and 65 individuals from 26 and 13 populations of A. thunbergii (including var. thunbergii, var. deltoids, and var. teretifolium) and A. sacculiferum, respectively, were studied to determine their ploidy. The geographic structure and habitat differentiation of the cytotypes were also analyzed. The main cytotype of A. thunbergii was diploid (92.3% in total; the rest were tetraploids). In contrast, the majority of A. sacculiferum plants were tetraploids (69.2% of the total; the rest were diploids). No populations of the studied taxa harbored both cytotypes. Allium thunbergii was more often found at higher elevations than A. sacculiferum, and it tended to occur more frequently on rocky slopes and below forests in mountainous areas. On the other hand, A. sacculiferum occurred at forest margins and in lowland pastures. The cytotypes differed with respect to the elevation; diploids were found more frequently at higher elevations than tetraploids. The results of this study and additional biosystematics data indicate that the morphological characteristics of A. thunbergii and A. sacculiferum may be influenced by polyploidization and by their adaptation to various habitat conditions and that A. thunbergii and A. sacculiferum do not clearly fulfill the requirements of any species concept. Consequently, we propose that A. sacculiferum be considered as an additional synonym of A. thunbergii. Additionally, Allium thunbergii var. deltoides is unified into A. thunbergii var. thunbergii.
