富有단감의 樹勢別 가지의 生長과 果實의 肥大 및 日燒被害에 미치는 影響 = Effect of Tree Vigor of 'Fuyu' Persimmon (Diospyros kaki L.) on Branch Growth, Fruit Enlargement Growth and Sun Scald Injury

국문 초록 (Abstract)

'富有'단감의 樹勢別 가지의 生長과 果實의 發育 그리고 日燒果의 發生을 調査한 結果는 다음과 같다. 樹高 및 樹輻에 있어서는 樹勢가 强할수록 樹高가 높았고 樹勢가 弱할수록 樹高에 比해 樹輻이 큰 편이었다. 果實數, 葉數, 果實 1個當 葉數는 樹勢가 强할수록 많았다. 日燒被害果率은 樹勢가 强할수록 낮았고, 弱할수록 높았다. 方向에 있어서는 南, 西, 東, 北의 順位였고, 北쪽은 樹勢別 關係없이 낮았다. 新梢의 伸長은 長果枝, 短果枝 共히 6月 이후는 微微하였으며 葉數는 減少의 傾向이 있었다. 그러나 伸梢의 굵기는 繼續 增加하였다. C의 含量은 短果枝가 많았고 N의 含量은 長果枝가 많았으며, C/N율은 短果枝가 높았다. 長果枝는 果實이 크고 果形指數가 높았으며 短果枝는 硬度가 높았다. 果實 部位別 硬度는 頂部가 側部보다 높았다.

Effects of tree vigor of 'Fuyu' persimmon on growth of branch, fruit enlargement growth and sun scald injury were examined, and the results obtained are as follows. The stronger tree vigor was, the higher tree height was and the weaker tree vigor was, the longer tree spread than tree height was. Number of fruit, leaf and number of leaf per a fruit were increased with strong tree vigor. Ratio of sun scald injury fruit was decreased with strong tree vigor and increased with weak tree vigor. In direction, ratio of sun scald injury fruit was south, west, east and north in order and north was low without relation of tree vigor. In elongation of shoot, both long fruiting branch and short fruiting branch are slight and leaf number seemed to decrease. Nevertheless, diameter of shoot increased continually. The content of C was high in shorting fruiting branch, the content of N was high in long fruiting branch and in C/N ratio, short fruiting·branch, was high. Fruit transverse was long and shape index of fruit was high in long fruiting branch and fruit firmness was high in short fruiting branch. In fruit firmness at parts, apex part was higher than side part.
