      • 硬實 PYracantha種子의 發芽矛措에 關한 硏究

        愼英範,徐榮敎,李基徹 慶北大學校 새마을硏究所 1978 農村과 科學 Vol.1 No.-

        The authors studied on the germination of hard coated pyracantha seed. The seeds were treated with gibberellic acid, concentrated sulphuric acide, chilling, hot water soaking and soaking in water. The results obtained are summarized as follows: 1. Germination rate were increased by hot-water soaking, gibberellic acid treatment and concentrated sulphuric acid treatment, while decreased by chilling and soaking in water. 2. Decreased germination rate by chilling and water soaking can be increased by concentrated sulphuric acid treatment. 3. Maximum germination rate was 19-24% in control, 28%in gibberellic acid treatment, 52% in sulphuric acid treatment and 91% in hot-water treatment. 4. Most effective temperature and duration for hot-water treatment was 30 to 90 minutes at 40℃. 5. Germination rate was lowed at 30℃ than 20℃ at seed bed.

      • 대구시(大邱市) 인근 3지역(地域) 사과 '후지'의 과실품질(果實品質) 비교(比較)

        신영,차은경,히토시 우에마츠,사카에 쿠보 경북대학교 농업과학기술연구소 1997 慶北大農學誌 Vol.15 No.-

        산지(영천군 청통면 신원리), 평지(영천군 신령면 연정리) 강변지(영천군 금호읍 냉천동)의 과수원에서 각각 '후지'과실을 채취하여 대구시 인근의 과실품질을 조사하였다. 결과는 다음과 같다. 1 각 지역 공히 품질이 평균적인 과실을 채취하였고 강변지 과실 중량이 40g정도 작았고, 과실종경 최소치가 다른 지역에 비해 작았다. 평지 과실의 횡경은 최대치, 최소치 모두 산간지보다 큰 것으로 나타났다. 과형지수는 강변지 과실이 다른 지역에 비해 편원형이었다. 이러한 과형의 차이는 온도, 토양수분함량 등에 의한 것으로 생각된다. 과실 착즙률은 각 지역간 유의한 차가 인정되지 않았다. 2. 각 지역 공히 후지과실 전당의 50%정도가 프락토즈인 것으로 나타났고, 산지의 슈크로즈, 프락토즈, 솔비톨 함량이 다른지역에 비해 높은 수치를 나타내었으나 글루코즈는 다른 지역에 비해 낮은 수치를 나타내었고, 당도는 전당함량과 거의 같은 수치를 나타내었다. 3. 각 지역 공히 후지과실 전산의 98% 정도가 능금산이었고 시트르산이 2%를 차지하였다. 산지과실의 능금산 함량이 다른지역에 비해 높은 수치를 나타내었고 적정산은 전산함량과 거의 같은 수치를 나타내었다. This investigation was attemped to know fruit quality of apple 'Fuji' grown at three different areas of Taegu. Fruits were gathered from hill side area : Kyungsangpookdo yongchongun chongtongmynn synwonri, flat area : Kyungsangpookdo yongchongun synyoungmyun youujeongri and river side area : Kyungsangpookdo yongchongun kewmhoyeub naenhchundong. Results were as follows: 1. In fruit sampling, we made an effort to select the same size of fruit from all areas, However, the size at river side area was about 40g lighter and minimum length was shorter than those of the other areas. On the other hand, maximum and minimum diameter of the fruit at flat and river side areas were longer than hill side area. Accordingly, shape index of the fruit in river side area was flatter than the other areas. This difference may be due to temperture, soil moisture content, etc. In squeeze rate of the fruit, no significant difference was recognized among areas. 2. Though, rate of fructose in total sugar was almost 50% in all areas, sucrose, fructose and sorbitol concentration of hill side area were higher than the other areas. however glucose was reverse amd brix was almost same as total sugar concentration. 3. Rate of malic acid in total acid was almost 98% and citric acid was only 2% in all areas. Malic acid concentration of hill side area was higher than the other areas and titratable acid concentration was almost same as total acid.

        3 배체수도(倍體水稻)의 세포유전학적 연구

        신영,이창덕,김춘아 한국유전학회 1982 Genes & Genomics Vol.4 No.1

        Five autotetraploids of the cultivated rice were crossed to diploid varieties, Lead rice, Tetep, TKM-6, Carreon, IR747 and Mudgo which were resistant to blast, bacterial leaf blight, stem borers and plant hoppers. Twenty one triploids from above crossed were investigated cytogenetically. The average rate of successful crossed between the resistant cultivars and autotetraploids was 1.61 percent. From the morphological point of view awn, giant spikelet, roughness of stem and leaf which reflect polyploidy and hybridization were observed in triploids. The pairing modes of chromosome in the first metaphase (MI) in P.M.C. depended on the lines; two lines had a mode of 11 III+1 II+1 I, eleven lines 10 III+2 II+2 I, six lines 9 III+3 II+3 I, and two lines 8 III+4 II+4 I. The average number of trivalent per cell was in the range of 8.08 to 10.06. Lagging chromosome, abnormal tetrad and non-simultaneous division mere also observed.

      • 園藝作物 (果樹)의 營養生理에 關한 硏究 : 사과의 Mn過剩障害에 對한 Ca 및 熔成燐肥의 效果 Effects of CaCO_3 and Fused Phosphate on the Excess Mn Disorder of Apple Tree

        愼英範 慶北大學校 새마을硏究所 1979 農村과 科學 Vol.2 No.-

        矮性사과나무의 Mn 過剩의 障害에 對한 對策을 세우기 위하여 용성인비 및 CaCO_3를 處理한 結果 나타난 效果를 다음과 같이 要約한다. (1) 용성인비의 處理에서 三葉, MM106 및 M26이 全部 處理量이 많을수록 Mn 含量의 減少量이 많으며 矮性台木 中에서도 M26이 MM106보다 減少量이 적었으며 三葉은 MM106 이나 M26보다 減少量이 많았다. (2) CaCO_3 處理에서는 10g 處理區에서 3品種 全部 Mn 處理區보다는 매우 적은量이 增加하였으나 50g과 100g 處理區에서는 減少되었으며 處理量이 많을수록 減少量이 많았고 品種別로 보면 용성인비의 경우와 같은 傾向으로 矮性台木 中에서 M26이 MM106보다 減少量이 적었으며 三葉은 MM106이나 M26보다 많았다. (3) 症狀은 CaCo_3 處理는 50g과 100g區는 거의 正常으로 回復되었으며 10g 處理는 停止狀態였고 용성인비 處理區는 50g과 100g에서 回復되었으며 10g 處理는 三葉과 MM106은 症狀이 줄어들었으나 M26은 많아졌다. Effect of fused phosphate and CaCO_3 treatment on excess Mn disorders of the dwarf apple tree was studied. Fused phosphate application at the rates of 50g and 100g per pot markedly reduced Mn content in the leaves of Malus sieboldii, MM 106 and M26 root stocks, showing the highest reduction with Malus sieboldii followed by MM106 and M26. 10g of CaCO_3 application slightly increbsed Mn content in all treatments, but Mn content decreased as CaCO_3 rates increased, showing the highest CaCO_3 rate with the lowest Mn content. Response of CaCo_3 to various rootstocks was similar to the tendency obtained by the fused phosphate application. 50g and 100g of CaCO_3 application almost normally recovered the internal bark necrosis symptom in all treatment, but 10g of CaCO_3 stopped only futher development of internal bark necrosis. Fused phosphate treatment at 50 and 100g rates showed also good recovery of internal bark necrosis, but 10g of fused phosphate application slightly reduced it in both Malus sieboldii and MM106, and was not effective on M26.

      • 水質汚染이 園藝作物生育에 미치는 影響 Ⅰ.금호강의 河天水 灌水處理가 사과와 포도樹??內의 重金屬 含量에 미치는 영향

        愼英範,鄭三澤 慶北大學校 1984 農業科學技術硏究所報 Vol.1 No.-

        重金屬 Cr, Cd, Zn, Pb의 溶液과 금호강의 本流 및 支流의 河川水를 사과苗木과 포도苗木에 灌水處理하여 重金屬의 吸收量을 측정 검토한 結果를 要約하면 다음과 같다. 1. 溶液處理에서 Cd, Cr, Zn, Pb의 各 濃度에서 低濃度에 比하여 高濃度溶液處理 일수록 사과와 포도의 葉과 新梢內의 含量이 많았다. 2. 河川水의 本流處理는 江下流인 1, 2番地點의 河川水를 處理한 것이 사과와 포도의 葉과 新梢에서 Zn, Cd, Pb, Cr의 含量이 많았으며, 上流인 3, 4番地點은 1, 2番地點에 比하여 含量이 적었으며, Zn은 1番地點, Cd는 2番地點, Cr는 1番地點, Pb는 1,2番地點이 가장 많이 含量되어 있었다. 3. 河川水의 支流處理는 9番支流가 Cr, Cd, Zn에서 含量이 가장 적었으며 Pb는 상당히 많이 含有되어 있었다. 8番地流는 Zn이 가장 많이 含有되어 있었으며 Cr, Pb는 적음 함량이었고, 5, 6番支流는 調査支流中에서 Cr, Pb, Cd, Zn에서 中間정도였고 6番支流는 Cr, Pb, Cd, Zn, 모두 含量이 많은 편이었다. Heavy metal absorption by apple and grape trees cultivated with Cd, Cr, Zn, and Pb-contained and river water were measured in 1983 ad the results obtained were as follow: 1. Content of heavy metal in leaf and shoot of apple and grape were appeared to be with application of higher concentration of heavy metals than with that of the lower one. 2. Watering with river water of main river showed lowered concentration at site No. 1 and 2. Zn was higher at site No. 1, Cd No. 2, Cr No. 1, Pb No. 1 and 2. 3. Watering with river water of branched river, the lowered concentration were appeared at site No. 9 in the content of Cr, Cd, and Zn while higher content in Pb. Higher contents of Cr, Pb, Cd and Zn were recognized at site No. 6.
