Endogenous ethylene measurements in relation to maturation and softening in kiwifruit.

Fruits were harvested from 4 kiwifruit orchards in 2 locations (2 at Rancagua and 2 at San Fernando, Chile). Orchards were selected based on previous information regarding different propensities to fruit softening. Fruit ethylene production rates (PR) and internal ethylene concentration (IE) were measured at harvest and during postharvest in fruits kept for 24 days at 20 deg C. Internal ethylene concentration was a suitable alternative for determining the status of ethylene in kiwifruits, compared with the normal method of measuring ethylene production. Depending upon ethylene levels present, IE showed a more defined increase throughout the harvest season and less variation between fruits within samples than PR ethylene measurements, thus allowing better discrimination than the more commonly used PR method. Endogenous ethylene and firmness, measured after harvest at 20 deg C and during cold storage, were not well correlated, indicating that endogenous ethylene alone is not a viable tool for pred

icting postharvest kiwifruit softening.
