温暖化がわが国の果樹に及ぼす影響について網羅的に把握することを目的として,全国の果樹関係公立試験研究機関に対して調査を行った.すべての都道府県が,温暖化の影響の発生について何らかの指摘をし,また,ほとんどの樹種に及んでいた.温暖化の影響は大きく2タイプに分類できた.ニホンナシ,モモ,ウメなどでは,開花期と成熟期がともに前進する,果実生育期前進タイプである.リンゴ,カキ,ブドウ,ウンシュウミカンなどは,開花期が前進する一方で,必ずしも成熟期は前進しない,果実生育期延長タイプである.後者では,着色不良,大玉化,低酸化,果肉軟化,貯蔵性低下等果実品質に関する変化が顕著であった.気象災害のうち凍害は常緑果樹やイチジクでは減少,その他の樹種では増加の指摘が多かった.晩霜害は地域により増加と減少の双方の指摘があった.

To grasp the actual influence of global warming on fruit tree production in Japan, a questionnaire was sent to prefectural institutes for fruit tree research. All 47 prefectures responded. All prefectures replied that global warming had affected on at least one tree species. The impact had extended to almost all tree species. The tree species were classified in to two types by responses of fruit development to climate changes. One group was the earlier development type and the other was the prolonged development type. The former were tree species in which both flowering and maturation periods had accelerated; these included Japanese pears, peaches and Japanese apricots. The latter were tree species in which the flowering period had accelerated, while maturation period had not accelerated; this type included apples, Japanese persimmons, grapes and satsuma mandarins. Fruit qualities of the prolonged development type had clearly changed, for example coloring faintly, enlarging, reduction of acid, softening and spoiling rapidly. Freezing injury on evergreen fruit trees and figs had decreased, while it had increased on other fruit tree species. Late frost damage showed both increase and decrease by region.
