The storage behavior of Satsuma oranges, as related to harvest date, was studied during 2 successive seasons. 1. At 20℃, Satsuma orange had a continually declining respiratory rate at all stages of development. Initial respiratory rates of fruits harvested as late as November 13 were higher than in fruits harvested prior to November 6. Also, the fruits were changing color from green to yellow between November 6 and 13. The chemical quantities measured were neary at the same level for all fruits harvested as late as November 26. From these, it seems that mid-November is changing point from development process to maturation. 2. During storage at 2℃, the breakdown rates of oranges, which harvested prior to November 20,were clearly higher than in fruits of harvested as late as November 26. Between before and after storage, the principal change in quality constituents was the acid decrease in juice. After storage, the quantitative differences in quality constituents were not observed among the times of harvest. From 1 and 2,it is evident that the storage life at 2℃ is greatly influenced by fruit maturity at the time of harvest.
