Amelioration of watercore in 'Fuji' apple viewed by two- and three-dimensional nuclear magnetic resonance imaging.

Non-invasive measurements relating to the curing of water core in Fuji apple fruits during storage were made over 2 seasons by serial analysis of multislice proton magnetic resonance images. The proportion of water core-affected tissue decreased linearly with time during storage (20 weeks at 0 deg C), the length of time taken for symptoms to disappear depending on the intensity of the disorder at commercial harvest. Percentage water-soaked tissue was greatest in centrally located image slices (both transverse and longitudinal) and declined towards the fruit's extremities. The difference between the distribution of affected tissue in basal and distal sections of the fruit was seasonally dependent; side-to-side comparisons, on the other hand, were essentially radially symmetric about the stem axis. Voxel seeding and volume rendering techniques applied to 3-D data sets of entire fruit, were also used to investigate the distribution of water-soaked tissues in 3-D space.
