Abstract:
The aim of this study was to evaluate temperature and modified atmosphere in the postharvest conservation of jambolao. The experiment was conducted at the Laboratory of Plant Physiology at the Universidade Tecnologica Federal do Parana - Campus Dois Vizinhos. The fruits at harvest point were collected manually and placed in a shaded container. After, they were taken to the laboratory where were separated into groups, part received biofilm application, part were coated with 10um thick PVC film, and the rest were not treated. Second, all were weighed to obtain initial weight and stored at 25 +_ 5'C, 15'C and 5'C. All treatments were placed in expanded polystyrene trays. The experimental design was completely randomized with factorial 3 x 3 (storage temperature x modified atmosphere), totaling 9 treatments with 4 replicates of 20 experimental units. Every two days the treatments were weighed and evaluated visually by the same person to verify percentage of rottenness and wilting of the fruits. After 10 days, the trays with the fruits were discarded. For postharvest preservation of jambolan it is recommended to pack it in trays with PVC film stored at a temperature of 5'C.
