중국 천진 지역의 원예작물에서 칼슘화합물 엽면살포가 잎의 칼슘함량 및 품질에 미치는 영향
문병우,김영호,Lu, Wen Long 한경대학교 2003 論文集 Vol.35 No.-
Tree-spray of liquid calcium compounds(LCC) extracted from oyster shell significantly increased the calcium contents of leaf in ‘Red star’ and ‘Fuji’ apple tree. The levels of shoot growth and fruit weight at harvest was increased by LCC treatment. The contents of soluble solids of ‘Red star’ and vitamin C of ‘Fuji’ were higher in LCC tree-spray. However, the acidity of fruit was not affected. The spray of LCC and calcium chloride were increased yield and the vitamin C contents of tomato fruits, but not on contents of soluble solids. Also, The foliar spray of LCC in Jinghai and Jinnan area were significantly decreased the occurrence of blossom-end rot in ‘Jinjiao-5’ tomato fruit. The fruit weight, yield, soluble solids and vitamin C of pepper and yield, coarse-fibred and vitamin C contents of chinese cabbage were increased by LCC foliar spray. Whereas, there was no difference plant weight and occurrence of bacterial soft rot among treatments in chinese cabbage.

The effects of organic calcium agent(ECa) tree-spray on the mineral nutrition concentration of petiole and fruit skin and quality in grapevines were studied. The calcium concentration of petiole and fruit skin at harvest in 'Campbell Early' by tree-spray after flowering 14days of calcium agent were increased significantly in calcium chloride 0.4%, ECa 250X and MCa 500X compared to control. The calcium concentration of petiole and fruit skin at harvest by ECa tree-spray after 7 days and 14 days flowering were increased significantly compared to control and 21 days after flowering treatment. Also, The calcium concentration of petiole and fruit skin at harvest by tree-spray of ECa 250X and 125X after flowering were increased significantly compared to control and 500X treatment. Fruit quality, fruit cluster weight, cracking fruit and Bitter rot occurrence by ECa tree-spray of treatment time and concentration different showed no difference between control. Phytotoxicity by tree-spray of ECa concentration different not occur to leaf and fruit.

The effects of organic calcium compounds (ACa) tree-spray for late growing stage on the mineral nutrition concentration of fruit, russet and quality in 'Fuji' apple were investigated. Optimum spray concentration of leaves by ACa tree-spray during late growth stage were ranged 125 times among 1,000 times. Also, Optimum concentration of fruits was effected to 125 times. Optimum spray times of leaves effected by ACa 500 times tree-spray during late growth stage were effective in one times (Sept. 25) and three times (Sept. 25, Oct. 5, 15). Also, Optimum times concentration of fruit skin was effected to one times (Sept. 25) and fruit flesh was effected two times (Sept. 25, Oct. 5) and three times (Sept. 25, Oct. 5, 15). Phytotoxicity by tree-spray of ACa concentration and times different not occur to leaf and fruit.
포도 '캠벨얼리'에서 GA<sub>3</sub>의 침지 시기와 농도에 의한 화수(花穗)생장 및 과실품질
문병우,이영철,남기웅,문영지,Moon, Byung-Woo,Lee, Young-Cheul,Nam, Ki-Woong,Moon, Young-Ji 국립한국농수산대학교 교육개발센터 2014 현장농업연구지 = Journal of practical agricultural resear Vol.16 No.1
This study has been conducted to investigate the treatment time and concentration of GA<sub>3</sub> solution dipping for labor saving in 'Campbell Early' grapevine. The rachis growth at harvest was reduced by GA<sub>3</sub> solution dipping before 5 days flowering, and increased significantly by GA<sub>3</sub> solution dipping treatment at full bloom and after 5 days full bloom. GA<sub>3</sub> 5, 10, 20 mg·L<sup>-1</sup> dipping treatment before 5 days flowering and GA<sub>3</sub> 20 mg·L<sup>-1</sup> treatment of full bloom and after 5 days full bloom showed a rachis twist phytotoxicity symptom. The optimum GA<sub>3</sub> concentrations for rachis growth promotion without phytotoxicity were 5 mg·L<sup>-1</sup> and 10 mg·L<sup>-1</sup>. The degree of compact berry, bloom, skin color, SSC and acidity at harvest by GA<sub>3</sub> solution dipping treatment time between concentration were not different from those of control. But the fruit berry weight was decreased by before 5 days flowering treatment when compared with control. There were no differences in full bloom and after 5 days full bloom treatment. The occurrence percent of berry cracking at before 5 days flowering and after 5 days full bloom treatment were significantly increased by GA<sub>3</sub> treatment. The bitter rot occurrence of berry at harvest was not affected by GA<sub>3</sub> treatment. Total rachis length of fruit cluster was increased by full bloom and 5 days after full bloom treatment. The length of rachis increased without reference to them position at full bloom and 5 days after bloom treatment. Accordingly, GA<sub>3</sub> 5 mg·L<sup>-1</sup> solution dipping treatment at full bloom and 5 days after full bloom were can be effectively for rachis growth promotion.

문병우,문영지,이영철,남기웅,Moon, Byung-Woo,Moon, Young-Ji,Lee, Young-Cheul,Nam, Ki-Woong 국립한국농수산대학교 교육개발센터 2015 현장농업연구지 = Journal of practical agricultural resear Vol.17 No.1
A study was conducted to examine treatment method, proper concentration, and treatment time of gibberellin(GA<sub>3</sub>) for human labor saving at harvest in 'Campbell Early' grapevine. Fruit berry thinning reduced labor by GA<sub>3</sub> 40ppm treatment of 5 days prior to full bloom, and, at GA<sub>3</sub> 10, 20, and 40ppm during full bloom, by 14.27~19.15 minutes/tree. Therefore, although labor was reduced by dipping treatment at 40ppm of 5 days prior to full bloom and 20 and 40 ppm during full bloom, severe shattering was observed at 40ppm dipping treatment, and soluble solids decreased, which suggests difficulty with commercialization. The result suggests that proper time and concentration of GA<sub>3</sub> fruit cluster dipping treatment at full bloom and 10 and 20ppm, respectively.

문병우,윤익구,문영지,남기웅,이영철,Moon, B.W.,Yoon, I.K.,Moon, Y.J.,Nam, K.W.,Lee, Y.C. 국립한국농수산대학교 교육개발센터 2013 현장농업연구지 = Journal of practical agricultural resear Vol.15 No.1
This study has been conducted to investigate the effect of Urea and K<sub>2</sub>SO<sub>4</sub> treatment at stone hardening stage and 20 days before harvest on soil chemical properties, mineral nutrient concentration and quality of 'Mibaekdo' fruit peach. K concentration after Urea and K<sub>2</sub>SO<sub>4</sub> treatment in soil was increased significantly by Urea 162g+K<sub>2</sub>SO<sub>4</sub> 188g/tree(standard amount) treatment at stone hardening stage, K<sub>2</sub>SO<sub>4</sub> 1.0% tree-spray, Urea 81g+K<sub>2</sub>SO<sub>4</sub> 94g/tree(half amount), Urea 162g+K<sub>2</sub>SO<sub>4</sub> 188g/tree and Urea 324g+K<sub>2</sub>SO<sub>4</sub> 376g/tree(double amount) soil treatment before harvest 20 days compared to control. T-N, K and Ca concentration in leaf was increased significantly by all treatment. but Na concentration in leaf was increased by Urea 0.5% and K<sub>2</sub>SO<sub>4</sub> 1.0% tree-spray treatment before harvest 20 days. T-N concentration in fruit skin was increased significantly by standard amount soil treatment, which decreased by K<sub>2</sub>SO<sub>4</sub> 1.0% tree-spray and half amount soil treatment. T-N, K and Ca concentration in fruit flesh(1~10mm depth flesh from peel) were increased markedly by all treatment excepted Urea 0.5% tree-spray. The leaf weight at harvest was increased markedly by Urea 0.5% tree-spray, standard amount and double amount treatment before harvest 20 days. Fruit weight was increased significantly by standard amount compared to all treatment. Red fruit skin(Hunter a value) progress was effective by K<sub>2</sub>SO<sub>4</sub> tree-spray, half amount and double amount treatment before harvest 20 days. Fruit SSC was increased significantly by Urea 0.5% and K<sub>2</sub>SO<sub>4</sub> tree-spray before harvest 20 days, standard amount treatment at stone hardening stage compared to control.
