Abstract
Nuclear Magnetic Resonance Imaging experiments have been performed on cherimoya fruit to provide an image contrast dependent on changes in water status.
Since those changes are concomitant to ripening we have assayed their relationship to physical destructive measurements conventionally used as ripening parameters.
Relaxation times (T1 and T2) were found to increase sharply at the beginning of the monitoring period, and more slowly afterwards.
Firmness evolution was found to be similar.
Regression analysis proved a good correlation between both measurements.
Results support the suitability of MRI as an accurate monitoring tool, both for basic research and for practical applications.
