휘가론과 에스렐 葉面撒布가 溫州蜜柑의 落果 및 果實品質에 미치는 影響

文斗吉,高康豪,韓海龍 濟州大學校 亞熱帶農業硏究所 1993 亞熱帶農業硏究 Vol.10 No.-

장마기 이전에 약제를 살포할수 있는 화학적 적과방법을 확립하기 위하여 탱자에 접목한 宮川早生 溫州蜜柑 (Citrus unshiu. Marcovitch cv. 'Miyagawa')을 공시하여 휘가론(5-chloroindazol-8-acetic acid ethylester)과 에스렐(2-chloroethylphosphonic acid)의 적과효과를 '87∼'92년 6년간 시험한 결과를 요약하면 다음과 같다. 1. '87∼'90 4년간 시험에서 제 1차 생리낙과가 거의 끝나는 6월 15일전후 (과경 10∼16㎜인 시기)에 휘가론 50mg/l 살포로 최종착과수를 20∼30%정도 감소시키는 적과효과를 얻을수 있었다. 그러나 무처리구의 최종엽과비가 14이하로 착과과다인 경우는 휘가론 단독살포만으로는 목표엽과비에 접근하기 어려웠다. 2. 만개 후 20∼25일인 6월 13∼15일에 엽면살포한 휘가론 (50mg/l)과 에스렐 (5∼200mg/l)의 낙과촉진 효과는 相加的으로 작용하여 두 약제 혼용살포구에서 그리고 에스렐 농도가 높을수록 낙과가 많았다. 3. 50mg/l이상 농도의 에스렐은 낙엽율을 증가시켰는데 휘가론 혼용은 에스렐의 의한 낙엽증가를 경감시켰다. 4. 착과안정기의 엽과비는 '91년도는 대조구 14에 비해 에스렐 25mg/l 단독살포구 36, 휘가론 50mg/l 가용 에스렐 12.5mg/l 살포구에서 39가 되었으며 '92년도는 대조구 10.5에 비해 에스렐 10∼40mg/l 단독살포구에서 17∼18, 휘가론 50mg/l 가용 에스렐 5∼20mg/l 살포구에서 14∼24였다. 5. 만개 후 15일부터 1주 간격으로 5주간에 걸쳐 에스렐 20mg/l의 살포시기를 달리한 결과 모든 처리에서 살포 후 2주째에 낙과가 급증되었다. 최종낙과율은 비록 살포일 사이에 유의차는 인정되지 않았지만 살포시기가 가장 빨랐던 6월 8일 살포구와 가장 늦었던 7월 8일 살포구와 가장 늦었던 7월 6일 살포구에서 많았다. 6. 화학적 적과의 실증실험에서 '91년도는 대조구의 착과안정기 엽과비가 16.9였는데 비하여 휘가론 50mg/l 살포구는 21.6 휘가론 50mg/l+에스렐 50mg/l 혼용구는 196.5로서 에스렐 50mg/l 가용은 적과과다에 의한 착과과소 상태를 초래했다. '92년도 시험에서는 대조구의 엽과비가 12.2였는데 비하여 휘가론 50mg/l 과 에스렐 20mg/l 단용구 및 혼용구의 엽과비가 각각 15.2, 15.6, 21.3이였으며 휘가론 혼용은 에스렐에 의한 낙엽율 증가를 경감시켰다. 7. 적과정도에 따라 과실크기가 증가하였으며 특히 과육중의 증가가 인정되었으나 착과과소상태의 경우를 제외하고는 과즙의 감미비에는 별 영향이 없었다. 8. 만개 후 20∼25일이 되는 6월 10∼15일경과경이 10∼15mm인 시기에 휘가론 50mg/l의 단독살포 또는 착과정도에 따라 20mg/l 전후의 에스렐을 혼합 살포함으로써 적절한 적과효과를 얻을 수 있다고 생각되었다. In order to establish the chemical fruit-thinning method of applying thinning agents before rainy season, the effect of Figaron (5-chloroindazol-8-acetic acid ethylestel) and Ethrel (2-chloroethylphosphonic acid) was evaluated in 'Miyagawa' Satsuma mandarin (Citrus unshiu Marcovitch cv. Miyagawa) grafted on trifoliate orange stock during '87-'92. The results obtained are summarized as follows: 1. Foliar spray of Figaron (50mg/l) on about June 15 accelerated fruit-drop, resulting in the decrease in the number of fruits by 20-30%. In case of over-fruit load less then 15 of final leaf-fruit ratio in Control, however, it was calculated that the ideal leaf-fruit ratio could not be obtained by the application of Figaron alone. 2. When foliar-sprayed on June 13-15 (20-25 days after full bloom), Figaron (50mg/l) and Ethrel (5-200mg/l) additively accelerated fruit-drop, resulting in more fruit-drop by more concentrated Ethrel with Figaron. 3. Higher concentration of Ethrel more than 50mg/l increased leaf-drop ratio, and the effect was reduced by Figaron. 4. The numbers of leaves per fruit in '91 were 14, 36 and 39, respectively, in the plots of Control, 25mg/l Ethrel only, and 12.5mg/l Ethrel with 50mg/l Figaron. Those in '92 were 10.5, 17-18 and 14-24, respectively, in plots of Control, 10-40mg/l Ethrel only, and 5-20mg/l Ethrel with 50mg/l Figaron. 5. Foliar spray of 20mg/l Ethrel on 5 different days at one-week interval from 15 days after full-bloom resulted in the remarkable increase in fruit-drop ratio in the second week after spray. Though significant difference in the final fruit-drop ratio among the dates of spray was not statistically recognized, the highest was observed in the plots of June 8 and July 6. 6. In the practical test of chemical fruit-thinning in '91, the numbers of leaves per fruit after June drop were 16.9 and 21.6, respectively, in the plots of Control and 50mg/l Figaron, and that in the plot of 50mg/l Ethrel with 50mg/l Figaron was 196.5, resulting in too few fruits from excessive thinning effect. Those in '92 were 12.2, 15.2, 15.6, and 21.3, respectively, in the plots of Control, 50mg/l Figaron, 20mg/l Ethrel, and 20mg/l Ethrel with 50mg/l Figaron. Leaf drop caused by Ethrel was reduced by the addition of Figaron. 7. The size and weight of fruit, especially pulp weight, increased according to the degree of fruit-thinning, while the Brix/acid ratio in juice was not affected except in the case of too few fruits caused by excessive thinning. 8. It was suggested that practical fruit-thinning could be attained by the foliar spray of 50mg/l Figaron or the mixture of 50mg/l Figaron and 20mg/l or so(depending on the degree of fruit load) of Ethrel on June 10-15, or 20-25 days after full bloom.

바나나의 莖頂培養에서 얻은 培養苗(草長 70㎝)와 吸芽苗(草長 120㎝와 170㎝)를 栽植하여 1987年 11月부터 1988年 11月에 걸쳐 濟州大學校 亞熱帶農業硏究所內 하우스에서 生育과 收量을 比較한 結果를 要約하면 다음과 같다. 1. 莖葉의 生長은 培養苗에서보다 吸芽苗에서 좋았고 吸芽苗 中에서는 170㎝ 苗에서 더 좋았다. 2. 出穗 및 成熟까지의 日數는 培養苗에 비해 吸芽苗에서 많았으나 有意差는 없었다. 3. 果房當 果指數와 果掌數는 培養苗에서 많은 편이었으나 果指長과 果指重은 반대의 경향이었으며 果房重은 栽植苗 間에 差異가 없었다. 4. 收量構成形質中 果房重과 正의 相關이 認定된 것은 果指長, 果指重, 果掌重 等이었는데 培養苗에서는 果指直徑도 高度의 相關이 있었다. 5. 段階別 多重回歸分析에서 收量에 가장 크게 영향을 미치는 形質은, 培養苗와 170㎝ 吸芽苗에서는 果掌重, 果房當 果掌數 順이었고 120㎝ 吸芽苗에서는 果指重, 果房當 果掌數 順이었다. This experiment was carried out to elucidate the effect of planting materials (shoot-tip cultured plantlet and sucker) on the growth and yield in banana (Musa cavendishii Lamb. cv. Dwarf Cavendish), from Nov. 1987 to Nov. 1988 in the plastic film house at the Research Institute for Subtropical Agriculture, Cheju National University, Cheju, Korea. 1. The growth of leaf and pseudostem was better in the sucker than that in the plantlet, and better in the larger sucker(170㎝) than that in the smaller one(120㎝). 2. Sucker tended to spend more days to bunch head emergence and maturity, but no statistically singificant difference was recognized. 3. While more fingers and hands per bunch were obtained in the plantlet, longer and heavier fingers were obtained in the sucker. Bunch weight was not different among planting materials. 4. The bunch weight was positively correlated with the length and weight of finger, and the weight of hand. In plantlet, the diameter of finger also highly positively correlated with the bunch weight. 5. In multiple stepwise regression analysis, variables most closely correlated with the yield turned out to be the weight and number of hands in the plantlet and the sucker of 170㎝, and the finger weight and the number of hands in the sucker of 120㎝.

이준호,김은진,문두호 부산대학교 과학교육연구소 2016 교사교육연구 Vol.55 No.2

The purpose of this study was to develop a framework for science teachers to develop field work worksheets for field trips which integrate into the secondary school science curriculum. The proposed framework was used to develop student worksheets for science field trips and its validity was verified through secondary school science teachers responses on a questionnaire based on their insights into configuration, the suitability for students, the contents of learning, and the usefulness of the worksheets. The validity was also examined based on in depth interviews with several science teachers about the effectiveness of the worksheets. As the results yielded a mean validity of 4.4/5.0 based on the teachers’in depth interviews. The teachers recognized that field work worksheets for field trips actively enhanced their role in the field trip by encouraged student participation through introducing cognitive conflicts based on exhibits, interacting with students and the exhibits, then resolving the conflicts as changing their science misconceptions. This study concludes that the continual use of field work worksheets for field trips based on themes which integrate into the secondary school science curriculum should be used to educate students attending informal science education institutes.
