국부성 또는 침투성 액아억제제에 의한 연초식물의 액아억제
장종오,엄유리,이이,신주식,석영선 충북대학교 연초연구소 2006 煙草硏究 Vol.20 No.-
본 실험에서는 황색종 KF-118을 사용하여 적심 후 발생하는 액아의 생장을 약제처리법을 이용하여 억제하였다. 약제로는 침투성 액아억제제, 접촉성 액아억제제, 국부성 액아억제제 등 세 종류의 약제를 활용하였다. 약제를 처리한 후 액아의 길이, 생장률, 생중량, 건중량 등을 측정하여 액아억제제의 효과를 측정하였다. A, B, C, D, E 총 5가지의 액아억제제를 처리하였으며 무처리구를 포함한 총 6개의 처리구로 나누어 시험하였고, 각 처리구는 적심 직후, 적심 후 액아가 2 cm 이하로 자랐을 때와 4 cm 이하로 자랐을 때로 분류하여 5주씩 3반복으로 처리구당 총 15주를 시험하였다. 실험 결과 무처리구와 처리구는 액아생장에 있어 유의성 있는 차이를 보였으며 처리효과는 적심 직후에 약제를 처리했을 때 가장 높았으며, 다음으로 적심 후 액아가 2 cm 이하로 자랐을 때, 4 cm 이하로 자랐을 때의 차례로 나타났다. 또한 적심 직후 약제를 처리한 경우 A약제를 제외한 모든 액아억제제가 억제율 90 %를 넘는 우수한 결과를 보였다. Suckers were controled by suckercide treatment using a flue-cured tobacco cultivar, KF-118. Three types of suckercides, systemic suckercide, contact suckercide and local suckercide, were used. Length, growth rate, fresh weight and dry weight of sucker were measured after suckercide treatment. Five kinds of suckercides (A, B, C, D, E) were treated directly after topping, when sucker length shorter than 2 cm after topping, and when sucker length shorter than 4 cm after topping. Five plants were treated and three times repeated. The sucker growth rates of treated plant were significantly lower than those of untreated plant. The smaller the sucker size, the higher the treatment effect. All suckercides, except for suckercide A, showed more than 90 % sucker control rate when they were treated directly after topping.
煙草의 折衷被覆栽培에서 着根肥 施用이 初期生育에 미치는 影響

This experiment was conducted to investigate the effects of starter solution on the growth responses of flue-cured tobacco at the transplanting time, which had been cultivated with compromised mulching culture system, and to find out the ways to reduce the damages at the early growth stage due to low temperature and drought. The results were summarized as follows. 1.Soil moisture content of the compromised mulching plot at the early growth stage after transplanting was lower, 2∼4%, than that of the pit-covered mulching culture. 2.The growth of flue-cured tobacco during early growth stage in compromised mulching culture plot were delayed about 5 days compared to those of the pit-covered mulching culture. 3.200ppm of (NO4)2SO4, NH4NO3 and KNO3 application had accelerating effects on the early growth of tobacco. 4.By applying 200 and 300ppm of KNO3 and 100 and 200ppm of NH4NO3 as starter solution, the growth of length and width of largest leaf, plant height, weight of top and roots, root length were accelerated during early growth stage.
Four Unrecorded Wood Decay Fungi from Seoul in Korea
( Yeong Seon Jang ),( Sung Wook Lee ),( Seok Yoon Jang ),( Young Woon Lim ),( Jin Sung Lee ),( Jae Jin Kim ) 한국균학회 2012 Mycobiology Vol.40 No.3
During the investigation of Korean indigenous fungi from Seoul, three genera-Fuscoporia, Porostereum, and Trametopsis, and four species-Fuscoporia senex, Phlebia acerina, Porostereum spadiceum, and Trametopsis cervina were found. Their morphological characteristics were examined and their identification was confirmed by molecular analysis based on internal transcribed spacer (ITS) and nuclear large subunit ribosomal DNA region sequences. These fungi are new to Korea and registered here with descriptions.
Research Notes : The First Report of Antrodia sitchensis (Polyporaceae, Basidiomycota) in Korea
( Yeong Seon Jang ),( Ha Eun Choi ),( Young Woon Lim ),( Jin Sung Lee ),( Jae Jin Kim ) 한국균학회 2011 韓國菌學會誌 Vol.39 No.3
An unrecorded Antrodia species was collected in South Korea and based on morphological characteristics, the species was identified as Antrodia sitchensis. To confirm its affinity within the polypores, the phylogenetic relationships of A. sitchensis and allied species were established using large subunit rDNA sequences.

Ergothioneine is a natural compound with strong antioxidant properties. In this study, the effects of different nitrogen sources including ammonium nitrate, ammonium sulfate, sodium nitrate, and histidine in sawdust media were investigated to enhance ergothioneine contents in Shiitake (Lentinula edodes) fruit bodies. The addition of 0.2% ammonium sulfate in the growth media showed the highest enhancement of ergothioneine content in shiitake fruit bodies which was 1.7-fold higher than the control. On the other hand, histidine, a building block of ergothioneine decreased the concentration of ergothioneine significantly. Our results demonstrate that the cultivation of shiitake in sawdust media with suitable nutrients was effective to enhance its ergothioneine contents.
