Typhoon "MAEMI", happened in September 2003, hit the great damage to Gyeongnam province area. Especially, rice plant was lodged or severe leaf damage was caused. This study was conducted to find out the extents of leaf damage among different rice cultivars, and to evaluate rice yield and eating quality due to leaf damage after typhoon. Rice cultivars torn off over half of the flag leaf length (FLL) were one medium-late maturing cultivar (Donginl), medium maturing cultivar (Yeonganbyeo), eight early maturing cultivars (Samcheonbyeo, Jounghwnbyeo, Munjangbyeo, Taebongbyeo, Odaebyeo, Samhaegbyeo, Sobaegbyeo, Sinunbongbyeo), two long-il type cultivars (Samgangbyeo, Namcheonbyeo), and three special use cultivars (Heukseonchalbyeo, Jinbuchalbyeo, Yangjobyeo). Cultivars torn off below 1/10 FLL were eight medium-late maturing cultivars (Chucheongbyeo, Daecheongbyeo, Saechu cheongbyeo, Donganbyeo, Daeyabyeo, Hwamyeongbyeo, 방eongsanbyeo, Dongjinbyeo) and two medium maturing cultivays (Donghaebyeo, Gumobyeo2). The rest cultivars were tore off by 1/10∼1/2 ELL. In yield components, the longer was flag leaf damage, the lower was ripened grain ratio, grain weight and brown/rough rice ratio, which was severly impacted to late than to ordinary season cultivation. However, rice yield did not decrease up to tearing by 1/10 ELL. Head rice ratio decreased from flag leaf tearing over 1/10 ELL in late season cultivation. The longer was flag leaf damage, the lower was eating quality, which could not show significantly different.

The differential response of soybean cultivars with or without sulfur (S) application was observed under fold conditions. Plant biomass decreased by sulfur deficiency but the reduction was less in Bragg variety about 26 % relative to the control than other ones over 45%, probably due to less reduction in loaves and pods. The photosynthetic rate of Bragg cultivar was also unaffected by the absence of sulfur application while it depressed in other lines. Soybean cultivars were compared in terms of storage protein, protein quality and biomass production by application of sulfur nutrition. The storage protein concentration tended to decrease without sulfur application in all the cultivars, however the differential response of protein quality only by 11S/7S ratio to sulfur nutrition status was observed: For instance, Bragg cultivar had higher biomass and protein production but protein quality decreased at sulfur deficiency. On the other hand, biomass and protein production in other cultivars remained louver at sulfur deficiency but protein quality differed genetically in spite of sulfur nutrition status. These results suggest that the response of soybean to sulfur nutrition is controlled by genotypic difference and sulfur supply status.

This study was carried out to investigate the correlation between root diameter and ginsenoside composition of Panax ginseng C. A. Meyer cultivar Yunpoong. Dry matter ratio of main root was a little higher than that of lateral root and fine root, and that was higher by the increase of root diameter in the same root parts. Total ginsenosides composition of main and lateral roots increased by the decrease of root diameter, especially in lateral root. Similar resulted in fine root, but there was no significant difference where root diameter was below 2.5 mm. Except for ginsenoside-$Rg_1$, other ginsenosides component, PDs, PTs and total ginsenosides had highly negative correlation with the root diameter within whole root, main root+lateral root and lateral root+fine root, while $Rg_1$ had positive correlation with the root diameter.

Cruciferous vegetables are rich in biologically active compounds such as glucosinolates and have various health benefits. Among these vegetables, Kimchi cabbage (Brassica rapa L. ssp. Pekinensis) is one of the most popular leafy vegetables due to the presence of the highest amounts of numerous vital phytonutrients, minerals, vitamins, and antioxidants. This study aims to investigate the effects of six cultivars (Chundong 102, Asia No Rang Mini, Hwimori Gold, Asia Seoul, Wol Dong Chun Chae, and Asia Bbu Ri) on hairy root induction and glucosinolate biosynthesis in the hairy root cultures of Kimchi cabbage. Seven different glucosinolates, in this case sinigrin, gluconapin, glucoerucin, glucobrassicin, 4-methoxyglucobrassicin, gluconasturtiin, and neoglucobrassicin, were detected in the hairy root cultures of Kimchi cabbage. Among the different cultivars, Asia No Rang Mini was the most promising candidate for hairy root stimulation, as it achieved the highest values for the growth rate, root number, root length, transformation efficiency, and total glucosinolate content. Overall, the Asia No Rang Mini cultivar of Kimchi cabbage performed best as a promising cultivar hairy root culture for glucosinolate production.

To evaluate the effects of cultivar, environment, age and cultivation times on ginsenoside content among 8 wild populations of American ginseng (Panax quinquefolium), the concentrations of 6 ginsenosides in root were determined at the time of collection (T0) of plants from the wild and 1 year after (T1) transplanting the roots to each of two different forest garden locations. Both location and population had significant effects on root and shoot growth. Overall, ginsenoside Rb1 was most abundant. The second most abundant ginsenoside were Re and Rg1, however the contents of them were not significantly different from each other. Concentrations of Rg1 and Re were inversely related. Ginsenoside Re was influenced by population and location. Ginsenoside Rg1, Rb1, Rc, Rb2 and Rd were influenced by population, location and age. Ginsenoside levels were consistently lower but growth was consistently higher at the more intensively managed garden location.

The effects of sonication and vacuum infiltration on transformation efficiency was investigated by using immature embryos of Korean wheat as explants. Two Agrobacterium tumefaciens strains, KYRT1 and EHA105, carrying pCAMBIA 1305.1 were used. Transformation efficiency was demonstrated by the detection of $\beta-glucu-ronidase$ (GUS) activity. GUS expression showed clear difference among Korean wheat cultivars. Geurumil showed higher GUS expression efficiency $79.1\%$ compared with other cultivars. The effects of the duration of vacuum infiltration and sonication treatment showed a tendency high GUS expression efficiency by their combination. In comparison with other Agrobacterium strains, KYRT1 showed high efficiency in most Korean cultivars.

Objective: The 3×3 factorial arrangement was used to investigate if either high water-soluble carbohydrates (WSC) cultivars or suitable time of day that the grass cut could improve nutrient values and in vitro fermentation characteristics. Methods: The 3 cultivars were mowed at 3 diurnal time points and included a benchmark WSC ryegrass cultivar 'Premium', and 2 high WSC cultivars AberAvon and AberMagic, which contained, on average, 157, 173, and 193 g/kg dry matter (DM) of WSC, and 36.0, 36.5, and 34.1 g/kg DM of N during 7th regrowth stage, respectively. The fermentation jars were run at 39℃ with gas production recorded and sampled at 2, 5, 8, 11, 14, 17, 22, 28, 36, and 48 h. The rumen liquid was collected from 3 rumen fistulated cows grazing on ryegrass pasture. Results: High WSC cultivars had significantly greater WSC content, in vitro DM digestibility (IVDMD) and total gas production (TGP), and lower lag time than Premium cultivar. Methane production for AberMagic cultivar containing lower N concentration was marginally lower than that for AberAvon and Premium cultivars. Grass cut at Noon or PM contained greater WSC concentration, IVDMD and TGP, and lower N and neutral detergent fiber (NDF) contents, but CH₄ production was also increased, compared to grass cut in AM. Meanwhile, the effects of diurnal cutting time were influenced by cultivars, such as in vitro CH₄ production for AberMagic was not affected by cutting time. The IVDMD and gas production per unit of DM incubated were positively related to WSC concentration, WSC/N and WSC/NDF, respectively, and negatively related to N and NDF concentrations. Conclusion: These results imply either grass cut in Noon or PM or high WSC cultivars could improve nutrient values, IVDMD and in vitro TGP, and that AberMagic cultivar has a slightly lower CH₄ production compared to AberAvon and Premium. Further study is necessary to determine whether the increase of CH₄ production response incurred by shifting from AM cutting to Noon and/or PM cutting could be compensated for by high daily gain from increased WSC concentration and DM digestibility.

The purpose of this study was to investigate the inhibitory effect of enzyme activity and anti-proliferation of human cancer cell lines (HCT 116, NCI-H460 and MCF-7) of peanut skin depending on cultivars (Arachis hypogaea L. cv. K-Ol, cv. Sinpalkwang, cv. Daan, cv. Heuksaeng) and extraction solvent. Peanut skin was extracted with 80% ethanol, 80% methanol, 80% acetone, and distilled water, followed by analysis of the enzyme inhibitory activity and anticancer activity. Methanol extract of Daan cultivar most effectively inhibited ${\alpha}$-gluosidase (65.08%, 0.025 mg/mL), tyrosinase (82.49%, 2 mg/mL) and ACE (73.61%, 10 mg/mL). The inhibitory effect of peanut skin extracts on colon cancer cell (HCT-116), lung cancer cell (NCI-H460) and breast cancer cell (MCF-7) growth were investigate using MTT assay. The highest anti-proliferation of cancer cell line of peanut skin extracts was observed in the methanol extract of Daan cultivar. The cell viability on HCT 116, NCI-H460 and MCF-7 cell lines of methanol extracts from peanut skin of Daan cultivar was 48.13%, 41.03%, and 36.02% at $200{\mu}g/mL$, respectively. These results suggest that peanut skin extracts may mediate physiological activity, and provide valuable information for the use of peanut byproduct as a functional food material.
