본 실험은 분화 Boronia(Boronia heterophylla)에 있어서 화색 변화에 작용하는 주요인을 구명하고자 실시했다. 화색변화에 광조건과 수명연장제가 영향을 준다는 가설 하에 수명연장제로는 1-methylcyclopropene(1-MCP)와 aminooxyacetic acid(AOA)를 사용하였고, 수명억제제로는 ethephon을 사용하였다. 이들의 효과를 두 광 조건하에서 유지되는 식물체에 처리하여 효과를 비교하였다. 약제 8처리(대조구, 1-MCP 기화, 1-MCP 기화+ethepon 분사, AOA 분사 AOA 관주, AOA 분사+ethepon 분사, AOA 관주 +ethepon 분사, ethepon 분사)를 2가지 환경인 온실과 실내에 각각 배치하였으며 각 처리는 4반복으로 분할구배치법으로 임의배치 하였다. 온실의 환경은 습도 36.9% 평균기온 23.3℃, 맑은 날 광도 901μmolㆍm⁻²ㆍs⁻¹이고, 실내 환경은 습도 68.2%, 평균기온 17.5℃, 광도 35μmolㆍm⁻²ㆍs⁻¹로 유지되는 곳에서 실험하여 안토시아닌 함량, 화색 변화를 조사했다. 수명연장 및 억제제가 안토시아닌 함량과 화색변화를 줄 것으로 기대하였으나 무처리 뿐만 아니라 모든 처리 간에도 유의성이 없었다. 그러나 boronia의 안토시아닌을 높이고 화색을 유지하게 하는 데는 광 환경, 즉 광량이 많은 온실에서 유지하는 것이 실내에서 유지하는 것보다 더 효과적인 것으로 보아 광도가 화색변화에 주요한 요인으로 생각되므로 금후 보다 다양한 광도를 이용한 연구가 필요하다. This study was conducted to examine the effect of ethylene inhibitors [1-methylcyclopropene (1-MCP) and amininooxyacetic acid (AOA)] and light intensity on flower color deterioration of potted Boronia heterophylla plants. We tested 1-MCP and AOA as ethylene inhibitors or senescence-inhibiting chemicals, and ethepon as a senescence-promoting chemical. Along with two light conditions, lab and greenhouse, plants were treated with different combinations of chemicals and application methods (1-MCP vaporization, 1-MCP vaporization plus ethepon spray, AOA spray, AOA drench, AOA spray plus ethepon spray, AOA drench plus ethepon spray, and ethepon spray). The experiment was laid out in a split-plot design with four replications per treatment. The recorded environmental conditions in the greenhouse were 36.9% relative humidity, 23.2℃ temperature, and 901 μmolㆍm⁻²ㆍs⁻¹ light intensity, and in the lab were 68.2% relative humidity, 17.5℃ temperature, and 35 μmolㆍm⁻²ㆍs⁻¹ light intensity. The changes in anthocyanin content and flower color were measured. Although senescence-inhibiting and senescence-promoting chemicals were expected to cause changes in the anthocyanin content and flower color deterioration, there was no signigicant differences among the treatments. Since keeping boronia plants in the greenhouse, having higher light intensity, is more efficient than keeping them in the lab to maintain antocyanin content and the flower color, it is concluded that light intensity had a major effect, while senescence-inhibiting and senescence-promoting chemicals played a minor role. More research using a diverse light intensities are needed in the future.

본 연구는 재활용 PET-Bottle-Particles(PBT)가 함유된 4가지 생육배지를 이용하여 플러그묘 재배의 가능성을 실험하기 위해 유리온실에서 수행되었다. 토마토 ‘서광’의 플러그묘를 PBT 100%, peat moss 100%, 그리고 PBT 50%+peat moss 50%가 함유된 배지 및 상업적으로 이용되는 배지(토실이)를 대조구로 이용하여 육묘하였다. 128공 플러그 트레이에서 2004년 7월 12일에 파종하여 플러그묘의 생육은 파종 후 30일째 측정하였다. 모든 처리에서 95% 이상 발아하였다. 초장, 지상부 생체중과 건물중, 엽면적, 그리고 하배축 길이는 대조구에서 가장 컸다. 뿌리 길이와 무게는 PBT 100%처리에서 가장 컸으며, 이 배지의 pH는 7.3이었다. PBT 50%+peat moss 50%처리에서 엽면적과, 지상부 건물중이 PBT 100% 처리에서 보다 컸으며, peat moss 100%처리에서 가장 작았다. PBT를 사용함으로 인한 독성증상은 관찰되지 않았다. 이 결과는 원예 묘종 생산에 있어 배지의 물리성 개선을 위한 구성요소로써 재활용 가능한 PBT의 이용 가능성을 제시해 준다. This study was conducted in a glasshouse to examine the possihility for cultivation of plug seedlings using four growing media containing recycled PET-bottle-particles (PBT) as a medium component. Plug seedlings of 'Seokwang' tomato were grown in media containing 100% PBT, 100% peatmoss, or 50% PBT+50% peatmoss. A commercial plug medium (Tosilee) was used as the control. All seeds were sown in 128 cell plug trays on July 12, 2004. Seedling growth was measured at 30 days after sowing. Percent seed germination was greater than 95% in all treatments. Plant height, shoot fresh and dry weights, leaf area, and hypocotyl length were the greatest in the control treatment. Root length and weight were the greatest in the 100% PBT treatment, which had a medium pH of 7.3. Leaf area and shoot dry weight were greater in the 50% PBT +50% peatmoss treatment than in the 100% PBT treatment, while they were the smallest in the 100% peatmoss treatment. No toxicity symptoms caused by the use of PBT had been observed in any treatment. The results suggest a possibility of recycled PBT, a valuable reusable resource, to be used as a component for medium amendments in horticultural transplant production.

The reform measures to solve the structural problems facing our animation industry were reviewed in view of animation businesses and government support. Korean animation businesses are requested to produce unique animations by enhancing their planning or creative capacity. Second, it is deemed necessary to concentrate the efforts on the TV animation allowing for a long-term stable revenues rather than the theater animation requiring a huge amount of capital. Third, it is essential to advance into niche markets other than theaters or TV. Fourth, in order to induce the investments, producers, broadcasting companies and large corporates need to form a consortium. Fifth, it is necessary to enhance the effect of ’window’ by taking advantage of the nature of animation as public goods and using the 'one-source, multi uses' strategy. Sixth, in order to improve the overseas marketing and distribution, domestic animation businesses are requested to associate themselves with the foreign counterparts strategically. Lastly, the digital animation technology should be more relied upon.

퍼펄라이트와 폐유리를 가공하여 입상화한 cellular glass foam(CGF)을 각각 입상암면과 파트모스를 혼합한 배지에서 매트저면관수한 Viola×wittrockiana ‘Majestic GT Scarlet Shadow’를 재배하여 개화와 생육을 조사하였다. 엽수, 분지수, 지상부 생체중과 건물중, 엽면적과 총엽록소 함량은 폐펄라이트+입상암면+피트모스 (25:50:25, v/v/v) 혼합배지에서 가장 좋았으며, 초장과 최대근장은 CGF+피트모스(25:75, v/v) 혼합배지에서 가장 좋았다. 대조구인 폐펄라이트+피트모스(25:75, v/v) 혼합배지와 비교하여 CGF+피트모스(25:75, v/v) 에서의 초장, 엽수, 근장, 총엽록소 함량, 지상부와 지하부의 생체중과 건물중이 더 컸다. 그러나 폐펄라이트+입상암면(25:75, v/v) 혼합배지와 비교하여 CGF+입상암면(25:75, v/v)에서의 생육은 매우 저조하였다. This research compared growth and flowering of potted Viola × wittrockiana ‘Majestic GT Scarlet Shadow’ in various mixtures of recycled perlite and cellular glass foam (CGF). The crop was cultured in a mat sub irrigation system. Numbers of leaves, opened flowers, flower buds, and branches, fresh and dry weights of shoot, leaf area, and total chlorophyll concentration were the greatest in plants grown in the medium of used perlite+granular rockwool+peatmoss (25:50:25, v/v/v). Plant height and length of the longest root were the highest and longest, respectively, in plants grown in the medium of CGF+peatmoss (25:75, v/v). The medium of CGF+peatmoss (25:75, v/v) was better than the medium of used perlite+peatmoss (25:75, v/v) in plant growth. The medium of CGF+granular rockwool (25:75, v/v) was poorer than the medium of recycled perlite+granular rockwool (25:75, v/v).

천미건(Mi Geon Cheon),김영봉(Yeong Bong Kim),김성란(Seong Ran Kim),이강모(Kang Mo Lee),홍광표(Gwang Pyo Hong),김진국(Jin Gook Kim) (사)한국생물환경조절학회 2015 시설원예‧식물공장 Vol.24 No.4

본 연구는 ‘진옥’ 포도의 안정생산을 위하여 무가온 하우스에서 착과량을 조절하여 2012년부터 2014년까지 3년간 수체생육 및 과실품질을 조사하였다. 처리내용은 10a 기준으로 1.3t, 1.8t, 2.2t, 2.4t, 2.6t의 5처리로 하였다. 시험결과 신초경, 신초장, 절간장 등은 처리간 비슷한 경향이었다. 숙기는 착과량이 많아 질수록 늦어지는 경향이었으며, 포도 ‘진옥’ 무가온 하우스 재배시 노지보다 수확기를 3주 정도 앞당길 수 있었다. 착과량이 많아질수록 수량은 많아졌으나, 평균과중은 착과량이 많을수록 작아져서 10a당 1.3t 착과한 처리구는 363g으로 가장 컸으며, 10a당 2.6t 착과한 처리구가 342g으로 가장 작았다. 가용성 고형물 함량은 착과량이 많아질수록 낮아지는 경향이었다. 수확 후 착과량에 따른 엽 및 신초내 무기성분 함량은 처리간 비슷한 경향이었다. 따라서 포도 ‘진옥’ 품종은 착과량이 2.4t/10a 이하이면 생산량에 따라 품질차이가 없으며, 가용성 고형물 함량 15°Bx 이상의 고품질 포도를 생산 할 수 있었으며, 위의 결과를 토대로 새롭게 육성된 ‘진옥’ 포도의 지속적인 고품질 안전생산을 통하여 농가 소득증진에 기여할 수 있을 것으로 사료된다. This study was conducted to investigate optimal crop loads of ‘Jinok’ grape for unheated plastic house culture. The crop loads of ‘Jinok’ grapes were managed to be 1.3, 1.8, 2.2, 2.4, and 2.6t per 10a from 2012 to 2014. We measured vine growth and berry qualities. Crop loads were not significantly affected on plant height, trunk diameter, shoot length, and the internode length of ‘Jinok’. However, the maturation of berries was delayed when the crop load was higher. And the harvest date was earlier about three weeks in an unheated plastic house compared to in an open field. The average berry weight was decreased by the higher crop load although higher crop loads made higher yields showing the lowest weight at 342g with the treatment of 2.6t per 10a and the highest weight at 363g with the treatment of 1.3t per 10a. Also, the soluble solids content showed a tendency that higher crop loads brought to lower degree Brix. The contents of P, K, Ca, and Mg in grape leaves and shoots were not significantly different by crop loads. To sum up, when crop loads were under the 2.4t per 10a, the berries were harvested as a marketable fruit having 15°Brix in the cultivar ‘Jinok’ grape. This result could help to increase grower’s benefit having improved quality of fruit for the sustainable production by the established cultivation techniques for the newly developed cultivar ‘Jinok’.
