  • This study investigated flavonoid, total phenol, total flavonoid content, antioxidant and antiproliferative activity on human breast cancer cells (MCF-7, MDA-MB-231). Four varieties of Korean green peppers (KP: kkuri pepper, PP: phut pepper, CP: cheongyang pepper, OP: ohi pepper) and one foreign green pepper (JP: jalapeno) were used. The contents of luteolin, quercetin and apigenin, which are abundant flavonoids in green pepper, were the highest in KP. Also, the contents of total phenol, and total flavonoids were the highest in KP, followed by CP, JP, PP, and OP (KP: total phenol $13.29{\pm}0.45$ mg GAE/g D.W., total flavonoid $7.02{\pm}0.13$ mg QE/g D.W. In DPPH ABTS radical-scavenging activity, KP showed the most potent antioxidant activity. In the result of viability in human breast cancer cells, KP had the highest antiproliferative effect. These results suggest that green peppers have significant antioxidant activity and can be a possible candidate for treatment of breast cancer.

  • Quarri green peppers were stored at $3^{\circ}C$ and $25^{\circ}C$, and capsaicin, ascorbic acid, chlorophyll, free sugars and surface color of the peppers were measured for 35 days of storage. Capsaicin and dihydrocapsaicin of quarri green peppers decreased during storage. The changes were bigger at $25^{\circ}C$ storage than at $3^{\circ}C$. Weight loss and decaying rate of the peppers were affected most by the increasing storage period and temperature. Ascorbic acid diminished remarkably at the beginning of storage period. Free sugars and chlorophyll decreased gradually during storage. Browning of quarri green peppers progressed slowly during storage not in pericarps but in seeds.

  • Nineteen pepper (Capsicum annuum L.) cultivars were screened for the resistance to two common species of root-knot nematodes, Meloidogyne incognita and M. arenaria. The tested pepper cultivars showed different degrees of resistance to M. incognita but all were resistant to M. arenaria. The cultivars cv. Gonggongchil, Green No. 500 Pimento, Dahonggeon, Manitta, Shinbaram, Perfecto, and Hanmaeum were resistant to the both species of root-knot nematodes. Therefore, seven selected resistant pepper cultivars are recommended as resistant rotation crops in greenhouses where root-knot nematodes are problematic.

  • Effectiveness of Orius strigicollis (Poppius) and Amblyseius cucumeris (Oudemans) as natural enemies against thrips were evaluated on greenhouse green pepper, sweet pepper and cucumber respectively. Control efficacy was calculated by the formula, $(D_{control}-D_{treatment})/D_{control}{\times}100$, where $D_{control}$ is the average density of thrips on the plots in which any natural enemy was not released and $D_{treatment}$ is the average density of thrips on the plots in which natural enemies were released respectively. As a result, control efficacies of O. strigicollis against Frankliniella occidentalis (Pergande) on green pepper and sweet pepper were $14.3{\sim}99.5%$ and $21.6{\sim}98.3%$, respectively. In addition, control efficacy of it against Thrips palmi Kany on cucumber was 61.2-74.4%. Control efficacies of A. cucumeris against F. occidentalis on green pepper and sweet pepper were $12.9{\sim}38.3%$ and $17.1{\sim}87.0%$, respectively. Control efficacy of it against T. palmi on cucumber was $90.4{\sim}97.4%$. Field evaluation showed that the prompt applications of natural enemies were effective to reduce the density of thrips. In detail, to control F. occidentalis effectively on green pepper and sweet pepper in spring season, five to six individuals of O. strigicollis per crops should be released three to six times continuously. To control T. palmi effectively on cucumber in autumn, more than 100 individuals of A. cucumeris per crop should be released four times repeatedly.

  • This study was carried out to investigated the water requirement of twisted sweet peppers which are cultivated in a green house. The meteorological conditions during the experiment period was close to that of normal year except the temperature and relative humidity. The growth status was improved with the increased saturation ratio. The range of the variation of daily water requirement were very large. The peak consumption occurred in the early August. And the higher saturation ratio resulted in higher water requirement. The total water requirement were about 57.180g/d/plant for pot with 100% (P100) of saturation , about 38.700g/d/plant for pot with 80%(P80) of saturation , about 23,720g/d/plant for pot with 60%(P60) of saturation, and about 53, 390g/d/plant for field cultivation in the green house, respectively. The water requirement was correlated with average ambient temperature and growing status, while no significant correlation were found between water requirement and minimum relative humidity or intensity of solar radiation. And the higher correlation was shown as the saturation ratio was increased. The transpiration coefficients of twisted sweet pepper were 378.0g/g for field cultivation in the green house, 363.3g/g for P100, 338.7g for P80 which was the smallest among pot cultivation , and 472.1g/g for P60 , respectively.

  • Protease activities were measured in vegetables used as cooking material or a side dish. Proteases of green pepper (Kwari and Chungyang), perilla leaves, soybean sprout and mungbean sprout were showed high activities. Especially, protease in soybean sprout was the highest activity among them. After dialysis, remaining activities in mungbean sprout, green pepper (Kwari and Chungyang) and perilla leaves were 12, 23, 45% and 37%. In the results of thawing after freezing the proteases, remaining activities in sprout of mungbean and soybean were 100% and 65%. Protease in soybean sprout was showed higher activity and stability than others. Proteolytic effects of soybean sprout on myofibrillar and sarcoplasmic protein were showed higher than stroma protein. In SDS-PAGE, myosin heavy chain, actin and tropomyosin were hydrolyzed with increasing time. Protease activity was rapidly increased with increasing meat concentration in a early proteolysis reaction, but was slightly increased in later.

  • The winter cherry bug (Acanthocoris sordidus Thunberg, Coreidae, Hemiptera) is a insect pest that have a piercing sucking type mouthpart, and it is injured to solanaceous plants including pepper plant. For the control of the winter cherry bug, 20 organic synthetic insecticides and 7 environmental friendly agricultural materials (EFAMs) were selected with single formulation. Fenitrothion, fenthion and phenthoate were significantly higher mortality to adults and 3rd instar nymphs of winter cherry bug as over 95 and 100 % after 72 hours with treatment. Otherwise, in case of EFAMs, there is no significantly higher effective materials to adults and 3rd instar nymphs of winter cherry bug. Eighty percentage of Sophora flavescens was showed only around 50% mortality with the high variation after 72 hours with treatment against adult of the winter cherry bug.

  • The winter cherry bug, Acanthocoris sordidus (Thunberg), is an insect pest hat damages plants from Solanaceae and Convolvulaceae. The developmental period from egg to adult averages 76 days at $25^{\circ}C$. Adult egg-laying occurred irregularly via spawning, averaging 195 (up to 468) eggs per individual on the abaxial leaf surface of the host plant. Results of linear regression indicated that the lower developmental threshold temperature was $13.9^{\circ}C$ and the effective accumulated temperature was 526.3 DD. Data from a pepper field in 2015 indicated that overwintering adults first appeared during late June (daily average temperature = $25.7^{\circ}C$), reaching maximum density by early September. A choice test examining colonization preferences using a net cage and a Y-tube olfactometer revealed that females gravitated toward conspecifics (other females, males, or both), whereas males moved toward empty areas. Finally, we found that communal breeding results in a longer developmental period and higher eclosion rates than solitary breeding. Developmental periods and eclosion rates were also for colonies in a large space than for those in a small space. This outcome suggests that colonization effects on insect development are stronger in a smaller area.
