Abstract

The Authors refert on «Valencia late» orange susceptibility to chilling injury in relation to picking period and storage temperature. Four fortnightly pickings have been carried out and two temperatures, 3° and 6°C, have been adopted. The results show a close relation between chilling injury and period of picking, particularly if the fruit are stored at 3°C. The fruits of the first and, in minor extent, those of the forth picking have been more resistant to the disorders than the second and third ones. At 6°C the percentage of affected fruits have been low with exception of the second picking. Therefore it appears that the optimal temperature, for «Valencia late» orange long-term storage, is 6°C which may vary depending upon fruit maturation stage.
