This study investigated the quality characteristics of mulberry cultivated under greenhouse and open field conditions. Quality characteristics such as the number of aerobic bacteria, pH, acidity, soluble solid content, and contents of free sugar, polyphenol, and anthocyanin were investigated. The number of aerobic bacteria in mulberry cultivated in open fields was higher than that of mulberry cultivated in the greenhouse. The average pH was significantly higher in greenhouse mulberry whereas acidity was higher in mulberry grown in open fields. The average soluble solid content of mulberry cultivated in open fields was slightly higher than that of mulberry cultivated in the greenhouse, although the difference was not significant. Fructose and glucose were detected in mulberry as free sugar. The free sugar content of mulberry was not affected by cultivation conditions. The average polyphenol contents of mulberry cultivated in the greenhouse and open fields were 393.36 and 514.47 mg%, respectively. The average anthocyanin contents of mulberry cultivated in the greenhouse and open fields were 205.00 and 265.56 mg%, respectively. The average polyphenol and anthocyanin contents of mulberry cultivated in open fields were significantly higher than those of mulberry cultivated in the greenhouse.

Consumption of wild edible greens (WEG) has risen in Korea recently, and processing of WEG at greenhouses is increasing. In this study, we investigated chamchwi (Aster scaber Thunb), a major WEG, to assess the effect of growth conditions on nutritional quality and blanching process. Field-grown chamchwi had 1.5-2-fold more total phenolic compounds and anti-oxidative capacity than the house-grown one. Among functional compounds, quercetin was significantly higher (about 5-fold) in the field samples (approximately $430{\mu}g/g$ fresh weight) than in the house samples. Soluble sugars in field-grown chamchwi were 2-fold higher than in the house samples. For both the samples, blanching process decreased chamchwi quality significantly, but the degree of loss for each component was different. Consequently, field-grown chamchwi exhibited superior nutritional quality than greenhouse-grown one, and blanching process resulted in a similar decrease of nutritional quality in both the samples.

우리나라의 가지 재배면적은 1970년 2,815ha이었던 것이 그 후 점차 줄어들어 2001년은 866ha가 재배되고 있고, 시설재배면적은 1970년 27ha로 전체면적의 1%도 채 안되는 매우 적은 면적이었으나 2001년에는 전체면적의 33%에 가까운 284ha가 재배되고 있다. 연간 총생산량으로 보면 1970년에 비하여 큰 차이가 없다. 이는 노지재배의 10a당 수량이 적을 때는 892kg 많을 때는 2,782kg 이나 시설재배의 10a당 수량은 1,617-4,294kg으로 노지재배에 비해 시설재배의 수량이 많기 때문이다(M.A.F. 2001).

In the year of 2002 annual nationwide survey of virus diseases occurring in the pepper fields and greenhouses in Korea, the distribution and the incidence of viral diseases was investigated. The pepper samples from both greenhouses (155 samples) and open fields (227 samples) were collected and further analyzed to detect eleven different viruses by RT-PCR. The results indicate that no sample collected from both greenhouse and open field seems to be infected by TMV, RMV, PVY, AMV, and TSWV. On the other hand, CMV, BBWV2, PepMoV, PMMoV, TMGMV and ToMV are readily identified from greenhouse and open field samples by RT-PCR. The infection rates of the collected samples between greenhouse and open field are largely different. Comparing with 10% of virus-infected pepper samples grown in greenhouse, approximately one third of pepper samples collected from open field are infected. The mixed-infection rates in the virus-infected greenhouse and open field samples are 16% and 61%, respectively. The dominant virus occuring in greenhouse is PMMoV, indicating that virus-infected seed stocks and infected plant debris in the growing area may be important sources of inocula. On the other hand, both CMV and BBWV2 are dominant viruses in open field. This may indicate that the migration of viruliferous insect vectors into pepper fields may be the most important source of inoculum. Also, the survey shows that BBWV2 is newly immerging virus to be controlled in Korea. The discrepancies on the distribution and the occurrence of viral diseases between field and greenhouse may provide a fact that the accumulation and distribution of inoculum by successive cultivation and the migration of viruliferous vectors into growing areas are likely to be important factors to determine the incidence of viral diseases. Therefore, the further studies on epidemiology and the consideration of new breeding program of pepper are essential to minimize virus diseases.

This study conducted an experiment with EC 1.0ms/cm ratio and excellent soil conditions for germination in ICT-based ginseng process cultivation. The first growth survey was conducted before transplantation of ginseng 1-year roots grown by seeding ginseng in the process cultivation, conventional cultivation and a second growth comparison survey was conducted after 3 months of growth. In the results, it was confirmed that ginseng grown in the process cultivation grew more than in the field. As a result of comparing the contents of 11 ginsenosides of 1-year and 2-year-old ginsenosides in the process cultivation and conventional cultivation ginseng, it was confirmed that the content of the process cultivation ginseng was higher than that of practice cultivation ginseng. In conclusion, conventional cultivation ginseng grows due to various factors under the natural cultivation environment, but process cultivation can secure the growth stability of ginseng by allowing stable soil and environmental control, so continuous research is needed in the future.
