| Outline of Final Research Achievements |
Fruit-set failure problem has so far no solution. We cannot help accepting the destructive damage caused by unexpected climate change when it occurs. However, the environmental effects on the tropical fruit reproductive physiology were not revealed. This was mostly owing to the lacking of useful devises to control microenvironment in the orchard conditions. Thu we manufactured temperature regulating devises using Peltier unit to regulate floral environment precisely in the orchards. The development of the floral organs before and after the pollination was then anatomically observed. The experiments were conducted in southern part of Japan and Thailand. The substantial results were obtained in cherimoya, lychee, passion fruit, durian.
