In this experiment, several commercial microbial fertilizers were tested to determine their effect on soil properties and the growth and fruit characteristics of ``Wooriccool`` watermelon. During 90 days, soil pH in ``EM1``, ``EM2`` and ``EM3`` significantly decreased, from 6.9 to 6.3. The microbial fertilizers except ``EM5`` seemed to reduce soil EC. Plant height and stem diameter were significantly longer in the ``EM2`` treatment, and the total number of leaves in ``EM1`` treatment was significantly greater than the control on growth characteristics of 32nd day after planting. In leaf length, ``EM5`` was significantly longer and the ``EM2`` treatment was shorter. Chlorophyll contents in ``EM2`` treatment was significantly higher them the other treatments. Stem length of 20-30th node was significantly longer in ``EM5`` treatment than the control on growth characteristics of 79th day after planting. Stem diameter in all the treatments was short and leaf width was significantly shorter in the ``EM2`` treatment. Fresh and dry weight of plants did not show a significant difference. The ftuit weight in ``EM3`` and ``EM4`` treatment were significantly higher at 8.6 kg and 8.6 kg respectively, but, there were not significantly different in soluble solids. EC in soil according to the number of soil irrigation by microbial fertilizer ``EM1`` and ``EM2`` did not show significant changes for 1 time but with ``EM1`` treatment for 15 days and 30 days after three times, it was reduced by 1.5 Ds. m-1, and 1.8 dS. m-1 respectively and in case of ``EM2`` treatment for 15 days and 30 days, it was reduced by 1.3 dS. m-1. Available phosphate content of soil tended to increase gradually compared with the initial time but it was small amount compared with the control of 781 mg. kg-1 except 30 days treatment of ``EM2`` that there were no significant differences. Among cation, with increase of the number of treatment, K+ had a tendency to increase in both the control and all treatments, Ca2+ and Mg2+ tended to increase in the control and others were decreased except for ``EM1`` for 15 days treatment. In the early growth stage, the stem length of 10 to 20th node with ``EM2`` for 30 days treatment was significantly shorter but leaf length, leaf width, petiole, and leaf area were significantly higher. Plant height and number of nodes on the late growth were significantly lower in ``EM2`` for 30 days treatment and significantly longer and more in ``EM1`` treatments. It did not show significant differences in other characteristics except that petiole length of ``EM1`` for 15 days treatment was significantly lower. Fresh and dry weight of plants were significantly heavy in ``EM1`` for 30 days treatment. And acute wilting degree was lower in all treatments, especially ``EM1`` treatments was lower. Fruit length on harvest time was significantly shorter in ``EM1`` for 15 days treatment, and fruit weight and soluble solids were a heavy tendency in all the treatments, especially ``EM1`` for 30 days treatment was significantly heavier.

본 연구는 전북 고창의 수박 시설 농가에서 ‘우리꿀’을 대상으로 토양의 이화학성, 생육 및 과실품질에 대한 정식 전 심경로타리 처리의 효과를 알아보고자 수행하였다. 정식 전에 비해 재배 및 수확 후 토양 pH 변화는 거의 없었으나 토양 EC는 크게 떨어졌다. 유기물 및 유효인산 함량은 두 처리 모두에서 증가하였는데, 유효인산의 누적 함량이 심경로타리 처리구에서 적었다. 치환성 양이온도 Mg을 제외하고는 모두 감소한 경향이었는데 심경로타리 처리구에서 K의 감소가 뚜렷하였다. 수박의 정식 후 27일째 생육 특성 중 일반로타리 처리구에 비해 심경로타리 처리구에서 초장, 10절까지의 줄기 길이, 엽폭에서 유의하게 길었고, 1번 및 2번화의 착과 절위가 낮았다. 그리고 육안 관찰 시 식물체 위조증상 정도이 적었다. 수확기에는 일반로타리 처리구에 비해 심경로타리 처리구에서 30절까지의 줄기 길이가 유의하게 길었고, 육안 관찰 시 잎의 횡변 현상이 적었다. 수확된 과실의 길이, 직경, 과피경도, 그리고 무게는 심경로타리 처리구에서 유의하게 높았다. To investigate effects of deep tillage before planting on physicochemical properties of soil, growth and fruit characteristics in cultivation of watermelon (Citrullus vulgaris L. cv. 'Uriggul') under plastic film house, this study was conducted in cultivating field of Gochang Junbuk. pH in soil after harvest compared with soil before planting of watermelon had almost no change, but EC lowed greatly in the two treatments. Available phosphate concentration in the soil with the deep tillage treatment was lower, K concentration of exchangeable cation decreased greatly than these with conventional tillage treatment. In the growth at 27th day after planting plant, stem length to 10th node from the first node, leaf width with deep tillage treatment were longer, bearing node of the first and second flower and wilting degree were lower than these with conventional tillage treatment. In the growth of harvesting time, the stem length to 30th node from the first node with the deep tillage treatment were longer, leaf discoloration degree was lower than these with conventional tillage treatment. Also, the harvested fruits length, diameter, peel hardness, and weight were significantly better than these with conventional tillage treatment.

배종향(Jong hyang Bae),한석교(Suk Kyo Han) (사)한국생물환경조절학회 2006 생물환경조절학회지 Vol.15 No.3

Chicory(Cichorium intybus L.)의 우량 종근 생산을 위해 파종 시기를 1개월 간격으로 하여 종근 형성 및 화아분화에 미치는 영향을 조사하였다. 화아분화 개시는 4월 파종은 6월 17일, 5월 파종은 7월 2일, 6월 파종은 7월 30일, 7월 파종은 10월 1일에 각각 화아가 분화되었으나 8월과 9월 파종은 전혀 분화되지 않았다. 파종시기별 생육특성에서 4~7월 파종은 종근의 무게가 150g에 도달하기 전에 화아가 분화되어 종근을 이용할 수가 없었으며, 9월 파종은 생육동안 외기온도가 낮아 겨울을 넘기면서 종근이 정상적으로 발육하지 못하는 결과를 보였고, 8월 파종은 파종 후 약 90일이 되는 시기에 Chion을 생산할 수 있는 종근의 적절한 중량인 200g이상의 이상적인 굴취기에 도달하였으며, 생육기간동안 화아분화가 일어나지 않았다. 따라서 우리나라 기후에 따른 우량 Chicory 종근을 생산하기 위한 적정 파종기는 8월인 것으로 조사되었다. Characteristics of the rootstock formation and flower bud differentiation according to sowing time for production of the high quality rootstock in Chicory (Cichorium intybus L.) was investigated. The flower bud initiation was on the 17th of July after sowing in April, the 2nd of July after sowing in May, the 30th of July after sowing in June and the 1st of October after sowing in July. But they didn't differentiate after sowing in August and September. The days required from germination to flower bud initiation and accumulated temperature depended on the weather. If the outside air temperature was high, the days required were less, If the outside air temperature was low, the days required were greater, the accumulated temperature was similar to the days required in this experement, too. The rootstock sown from April to July wasn't good enough to be use because the flower bud differentiation was generated before harvestable weight. the weight of rootstock was sown in September wasn't heavy enough in weight because the outside air temperature was too low for it to grow well. The plant grows slow and steady through out winter. The rootstock sown in August was havestable 200g in 90 days after sowing before the flower bud differentiated. The best sowing time for the production of high quality rootstock of Chicory in the climate of Korea is researched to be August.

은종선(Jong-Seon Eun),김준수(Jun-Su Kim),임환수(Hwan-Su Lim),한석교(Suk-Kyo Han),최소라(So-Ra Choi),장영석(Young-Seok Jang) 한국원예학회 2007 원예과학기술지 Vol.25 No.1

유채의 돌연변이 육종을 통한 조숙, 단간, 내한성, 내염성 등 농경상 유용형질을 개량하여 재배면적을 증대하고 biodiesel을 개발하고자 품종 ‘내한’, ‘탐미’, ‘한라’ 등의 종자에 양성자와 감마선을 0~2,000Gy 수준으로 처리하여 M1 세대의 방사선 감수성을 조사하였다. 발아율은 품종, 선종 및 선량에 상관없이 95.3% 이상이었고, 파종 6일 후 출현율은 선량이 증가할수록 유의적 감소를 보였으나 파종 12일 후에는 91.7% 이상 출현하여 비슷하였다. 파종 7주일 후 생존율은 1,000Gy까지는 비슷하였으나 1,500Gy와 2,000Gy에서는 38.1~84.1%로 현저하게 감소하였다. 파종 3주일 후 자엽장, 자엽면적 및 하배축장은 3품종 모두 양성자와 감마선의 선량 증가에 따라 급격히 감소하여 통계적 유의성이 인정되었으며 ‘내한’, ‘한라’, ‘탐미’ 순으로 예민한 반응을 보였다. 한편 ‘탐미’의 경우 양성자 처리구의 자엽장과 자엽면적에서 100~200Gy 처리구가 무처리구에 비하여 증가되는 hormesis 현상이 나타났다. 파종 1개월 후 엽록소 함량, 본엽수, 엽면적에서도 선종에 관계없이 선량 증가에 따라 통계적 유의성을 보였으며, 800Gy 이상 고선량구는 자엽이 거의 황화되었고 특히 ‘탐미’ 품종에서 황화현상이 심했다. 본엽수는 대조구와 저선량구에서 2.3매 내외이었으나 1,500Gy 이상 고선량구는 자엽만 전개되었을 뿐 본엽이 거의 생장하지 않았다. 대조구 엽면적의 50% 이상 감소선량은 양성자 처리구에서는 ‘내한’이 800Gy, ‘탐미’와 ‘한라’는 1,500Gy로 나타났고, 감마선 처리구는 ‘탐미’ 400Gy, ‘내한’과 ‘한라’는 1,500Gy로 나타났다. 지상부보다 지하부 생체중의 감수성이 높았는데 50% 이상 감소 선량은 ‘내한’ 600Gy, ‘탐미’와 ‘한라’는 1,000Gy로 나타났다. 유묘기의 생장반응에 있어서 1,000Gy를 초과한 선량에서 50% 이상 감소하는 매우 높은 감수성을 보여 육종에 효율적인 선량은 1,000Gy 이하로 나타났다. This experiment was carried out to increase the cultivation area of rape (Brassica napus) and develop this plant as a biodiesel so dry seeds of 3 cultivars, ‘Naehan’, ‘Hanla’, and ‘Tammi’ were irradiated with proton ion and gamma-ray at range of 0 to 2,000 Gy and then radiosensitivity of M1 generation were investigated. The germination rate were more than 95.3% regardless of radiation source, dosage and cultivar and emergence rate at 6 days after sowing were decreased by increasing dosage but those of 12 days as more than 91.7% were similar all together. Survival rate in 1,000 Gy and below at 7 weeks after sowing were similar but remarkably reduced 38.1~84.1% in 1,500 Gy and 2,000 Gy. The length and area of cotyledon, and hypocotyl length in all 3 cultivars were badly reduced with high significancy by increasing dosage of proton ion and gamma-ray irradiation and sensitive responses were showed in order of ‘Naehan’, ‘Hanla’, and ‘Tammi’. On the other hand, there was hormesis that the length and area of cotyledon were more increased at 100~200 Gy in the proton ion than control in ‘Tammi’. Chlorophyll content, number of true leaves and leaf area at 1 month after sowing were decreased by increasing radiation dosage regardless of radiation source so had high significancy. As the cotyledons at 1 month after sowing almost showed chlorosis in more than 800 Gy and chlorosis was especially serious in ‘Tammi’. The number of true leaves was about 2.3 in control and the low level of dosage but cotyledon didn’t grow in the high level dosage of 1,500 Gy and over. And the dosage in which leaf area was reduced to 50% compared to that of control were 800 Gy in ‘Naehan’ and 1,500 Gy in ‘Tammi’ and ‘Hanla’ by proton ion and 400 Gy in ‘Tammi’, 1,500 Gy both ‘Naehan’ and ‘Hanla’ by gamma-ray. The fresh weight of top land than root was more sensitive so dosage in which fresh weight reduced to 50% compared to that of control were 600 Gy in ‘Naehan’ and 1,000 Gy both ‘Tammi’ and ‘Hanla’. As the results, growth of seedling decreased over 50% in more than 1,000 Gy with high sensitivity to radiation and so it was appeared that proper dosage for mutation breeding in rape was 1,000 Gy and below.

본 연구는 활엽수 대상 용기묘의 적정 상토를 개발하기 위해 상토의 원료 조성에 따른 노각나무, 찰피나무, 이팝나무 등 활엽수 용기묘의 생장 특성을 4개월간 시설온실에서 실시하였다. 사용된 상토중 코코피드나 피트모스 등이 상대적으로 많은 상토에서 노각나무, 찰피나무, 이팝나무 등 활엽수 용기묘의 수고생장과 근원경 생장이 높게 나타났으며 지상부와 지하부의 건물 생산량 또한 뚜렷하게 증가한 경향을 보였다. 또한 생리적 특성에 있어서도 활엽수 용기묘의 광합성률이 상토내 코코피드와 피트모스가 많을수록 높아지는 경향을 보였다. 활엽수 용기묘의 생장에 대한 상토의 영향은 생장특성과 물질생산량 및 광합성과 같은 생리적 특성과 함께 관수 및 시비 체계도 지속적으로 연구해야 할 것이다. This study examined the growth characteristics of broad-leaved container seedlings of Stewartia pseudocamellia, Tilia manshurica and Chionanthus retusus in relation to the raw material properties of the container medium in a green house for 4 months in order to develop optimum container medium for broad-leaved container seedlings. Among the container media used, the high level of the height growth and root collar diameter growth of broad-leaved container seedlings of Stewartia pseudocarnellia, Tilia manshurica, Chionanthus retusus was found in the container media with relatively more cocopeat or peatmoss, and the dry matter production of the aerial part and the subterranean part. Also, concerning physiological characteristics, the photosynthetic rate of broad-leaved container seedlings increased in proportion to the volume of cocopeat and peatmoss in the container media. The effect of container media on the growth of broad-leaved container seedlings needs continuous study on the irrigation and fertilization programs along with the study on physiological characteristics including growth characteristics, biomass production and photosynthesis.
