不知火에서 봄순 및 여름순의 결과모지가 果實 品質 및 葉內 無機成分 含量에 미치는 影響

Abstract

This study was performed to collect the preliminary data about the fruit quality in fruits and the mineral content in leaves born at the bearing mother branches of summer and spring flush of 'Shiranuhi'〔(C. unshiu × C. sinensis) × C. reticulata)〕mandarin hybrid for protected cultivation. Fruit quality, leaf area, and mineral nutrient content for the bearing mother branches of summer and spring flush from 2009 to 2011 had been evaluated. In the comparison of fruit quality, the segment weight of fruits fruited at the bearing mother branches of spring flush was higher than that of summer flush with statistical significance, but there had not been statistical differences in the other physical characteristics. The leaf area at the bearing mother branches of summer flush was higher than that of spring flush. There was not statistical significances in the macro-element contents including N, P, K, Ca, and Mg between summer and spring flush at bearing mother branches through leaf analysis. The content of Fe and Zn of micro-elements were higher enough to be significant at summer flush than spring flush for bearing mother branches. The results of this study suggested that summer flush is nutritionally involved in the sustenance of tree vigor rather than fruit quality in 'Shiranuhi' mandarin hybrid.
