Guava (Psidium guajava L.) is a tropical fruit that presents fast post-harvest ripening: therefore it is a very perishable product. Inappropriate storage temperature and retail practices can accelerate fruit quality loss. The objective of this study was to evaluate the respiratory activity (RA), the ethylene production (EP) and Q10 of guava fruit at different storage temperatures. 'Paluma' guava fruits were harvested at maturity stage 1 (dark-green skin) and stored at either 1, 11, 21, 31 or 41°C; RA and EP were determined after 12, 36, 84 and 156 h of storage. RA and EP rates at 1 and 11°C were the lowest - 0.16 and 0.43 mmol CO2 kg-¹ h-¹ and 0.003 and 0.019 µmol C2H4 kg-¹ h-¹, respectively. When guavas were stored at 21°C, a gradual increase occurred in RA and EP, reaching 2.24 mmol CO2kg-¹ h-¹ and 0.20 µmol C2H4 kg-¹ h-¹, after 156 h of storage. The highest RA and EP were recorded for guavas stored at 31°C. In spite of high RA, guavas stored at 41°C presented EP similar to guavas stored at 11°C, an indicator of heat-stress injury. Considering the 1-11°C range, the mean Q10 value was around 3:0; the Q10 value almost duplicated at 11-21°C range (5.9). At 21-31°C and 31-41°C, Q10 was 1.5 and 0.8, respectively. Knowing Q10, respiratory variation and ripening behavior in response to different temperatures, fruit storage and retail conditions can be optimized to reduce quality losses. |
