Respiration rate, ethylene production, and cellular leakage of fig fruit following vibrational stress.

 

Fruits of the fig cultivars Masui Dauphine, Celeste and Brunswick were placed in plastic containers and held in place with cotton wool. The containers were vibrated for 10 min at accelerations of 1, 2, 3, 4, 5 and 6x g. Carbon dioxide production during vibration increased linearly with severity of vibration in all cultivars. Masui Dauphine generated more CO2 than the other cultivars and showed the highest rate of increase in respiration during vibration. Rate of ethylene production (for the 3 h from the start of vibration) increased with degree of vibration, and was highest and showed the greatest increase in Masui Dauphine. Cellular leakage (measured after vibration) increased with increasing vibration above 2x g. Leakage was higher at 1x g than at 0 or 2x g. Masui Dauphine had the highest rate of leakage over most of the range of vibrational force. The results indicate that this cultivar may be susceptible to vibrational stress. Although fruits exposed to up to 6x g did not show any visible da

mage, it is recommended that vibrational stress be avoided during postharvest handling.
