Background: Ginseng cultivation is conducted in sun-shade facilities, and farmers are demanding new cultivation facilities with high durability and reusability. Methods and Results: In this study, three different sun-shade facilities, slope-shading type (SST), small connecting-tunnel (SCTT), and gradient-tunnel (GTT) were compared in terms of temperature and ginseng growth. The highest temperatures recorded, occuring at 13:00 on August 9, were 42.9℃ for the SCTT and 40.9℃ for the GTT. The SST was 38.5℃ at this time point, which was the lowest of the three treatment. When temperatures above 33℃ were cumulatively calculated from June to August, the SCTT was higher by 2,731.7℃ and 124.5℃ than the GTT and SST respectively. Plant length, stem length, leaf length, and leaf width were significantly higher in SCTT and GTT than in SST. The root weight was 14.7 g, 14.5 g, and 15.3 g in the SST, SCTT, and GTT, respectively, with the highest root weight in GTT. Anthracnose incidence was marginally higher in SST; 1.7% for the SST, 0.3% for the SCTT, and 0.2% for the GTT. Damage caused by high temperature was the highest in SST (8.0%), and was lower in SCTT (5.7%) and GTT (7.3%). Conclusions: We found that SCTT and GTT facilities are safe for ginseng cultivation. Future studies should investigate ways to lower the temperature, such as by installing light-shield film.
β 단백질의 중합을 억제하는 살균제에 대한 인삼 잿빛곰팡이병균의 감수성 변화
김주형,민지영,백영순,배영석,김흥태,Kim, Joo-Hyung,Min, Ji-Young,Baek, Young-Soon,Bae, Yeoung-Seuk,Kim, Heung-Tae 한국식물병리학회 2007 식물병연구 Vol.13 No.3
2005년과 2006년에 인삼 잿빛곰팡이병균을 각각 89개와 147개씩을 분리하여 실험에 사용하였다. Carbendazim은 $EC_{50}$값이 $10.0{\mu}g/ml$ 이상을, carbendazim/diethofencarb 합제는 $0.2{\mu}g/ml$ 이상을 저항성 검정의 기준으로 하였다. 이 기준을 가지고서 두 종류의 살균제에 대한 저항성 균주의 분리 빈도를 조사하면 carbendazim의 경우, 2005년에 87.6%, 2006년에는 96.6%로 나타나, 포장에서 분리되는 대부분의 Botrytis cinerea가 저항성균인 것으로 밝혀졌다. Carbendazim/diethofencarb 합제의 경우에는 저항성 균주의 분리빈도는 2005년과 2006년에 각각 23.6%와 24.5%로 나타났다. Carbendazim/diethofencarb 합제는 지역에 따라서 저항성균의 분리 빈도가 크게 달랐다. 경기도 연천 지역의 경우 저항성 균주의 분리빈도가 2005년에는 4.3%였고, 2006년에는 저항성 균주가 전혀 분리되지 않았다. 이에 비하여 다른 지역의 경우 저항성 균주의 빈도가 크게 높았는데, 2005년에는 경북 봉화와 예천 그리고 경기도 파주의 저항성 균주의 빈도가 각각 35.5%, 70.0% 및 40.0%였고, 2006년에는 전북 정읍의 저항성 균주의 빈도가 47.1%였다. 따라서 carbendazim/diethofencarb 합제에 대한 저항성 검정이 포장에서 지속적으로 수행되어야 한다. In this experiment, 236 isolates of Botrytis cinerea isolated from the lesions of ginseng grey mold in 2005 and 2006 were examined for their sensitivity to fungicide inhibiting ${\beta}-tubulin$ assembly. The baselines of fungicide resistance were determined as 10.0 and $0.2{\mu}g/ml$ of $EC_{50}$ values for carbendazim and the mixture of carbendazim and diethofencarb, respectively. The ratios of isolates resistant to carbendazim in 2005 and 2006 was investigated to be 87.6 and 96.6%, respectively. In the case of the mixture of carbendazim and diethofencarb, the ratio of the resistant isolates was 23.6% for 2005 and 24.5% for 2006. The ratio of the resistant isolates to the mixed fungicide was fluctuated according to regions where isolates of B. cinerea were obtained. In Yeoncheon of Gyeonggi Province, 4.3% of the isolates used in the experiment was resistant in 2005 and no resistant isolate was obtained in 2006. Among 5 regions, the ratio of resistant isolates was the highest as 70.0% in Yecheon of Gyeongbuk Province.
