Both Aweta AFS and NIR are useful for segregating harvested kiwi for differential inventory management

Commercially harvested kiwifruit are inevitably variable as the consequence of strip harvest. Fruit of Actinidia deliciosa ?Hayward? and A. chinensis ?Zesy002? (marketed as ZESPRI? SunGold Kiwifruit) harvested on two occasions from 12 orchards (six orchards per cultivar) were measured using an Aweta acoustic firmness sensor (AFS) and a near infrared spectrometer (NIR) two days after harvest. Fruit were either destructively measured at harvest (30 fruit per orchard at each harvest) or cool stored at 1?C (180 fruit per orchard at each harvest). Storage life of each individual fruit determined by regular checking of firmness and disorders during cool storage was correlated to fruit attributes measured at harvest using either the Aweta AFS or NIR. Both Aweta AFS and NIR are useful for segregating harvested crops for differential inventory management. The merits and limitations of each instrument are compared for future implementation into commercial practice.
