Outline of Final Research Achievements

In order to improve the quality of fruits imported from Southeast Asia into Japan, we monitored the distribution environment conditions, found out the problems, and proposed the distribution environment conditions that would enable appropriate post-ripening. In addition, from the point of fruit quality, we verified whether the proposed distribution environment conditions were appropriate and confirmed that post-ripening was properly promoted.
It was clarified that the drought tolerance of fruit trees in the production environment can be verified using sap flow sensor. Furthermore, we show that machine learning can model the relationship between the concentration of CO2 in the rhizosphere and the water content.

Academic Significance and Societal Importance of the Research Achievements

低温感受性が高く低温で貯蔵した場合追熟不良が発生する熱帯産果実を対象にし，果実品質に影響を及ぼす流通環境条件を見出し，その条件を改善するような流通条件を提案することで，消費者が入手する際の果実品質の改善に貢献する．また，収穫時の果実品質を向上するための生産環境条件についても，環境モニタリングとモデリングにて可能なことを示した．
