| Popis: | We evaluated the effects of the immense damages due to the Kumamoto earthquake generated in April, 2016, such as collapse of stone walls, cracks, and subsidence, on the growth and fruit quality of fruit trees, e.g., Satsuma mandarins and persimmons. In the Satsuma mandarin orchards where the stone wall collapsed, with regard to the influence on growth, we did not observe a change with less than 20% degree of exposure of the roots. However, the spring shoots were short, the leaf color became light, and the fruit size tended to become small when the tree roots were further exposed. In the Japanese persimmon “Taishuu,” the shoots became shorter, and many fruits in the seriously damage orchards, which included cracks and subsidence, were observed to fall down before harvest time because of softening. 平成28年に発生した熊本地震により，石垣の崩落や圃場内の地割れ，または地盤沈下の被害があった果樹園における生育や果実品質に及ぼす影響について評価した。石垣が崩落したウンシュウミカン園では，根の露出程度が2割以下の樹では生育への影響は認められなかった。しかし，それ以上に根が露出した場合には，新梢が短く，葉色は淡くなり，果実肥大も抑制される傾向があった。カキ ‘ 太秋 ’ では，地割れや地盤沈下があった甚大被害園において，新梢長が短くなり，果実重が小さかった。加えて，収穫時までに軟化等で落果した果実が増加した。 |
