Measurement of relaxation times by bothNMRandMRIrevealed differences between locular and other tissues. The T2 and T1 relaxation times determined using both NMR and MRI decreased during ripening in all tissues except in the locular tissue, and these changes were attributed to the components with the longest T2 and T1. On the other hand, the T2 of the locular tissue had a more complex trend. NMR measurements showed that all of the T2 components of locular tissue cells were modified during ripening and that they followed similar patterns. Finally, the NMR measurements showed that the T1 decay in the locular tissue was mono-exponential, in contrast to the bi-exponential T1 decay of other tissues. A difference
between the structure of the locular tissue and other tissues was observed on the macrovision images. Whereas the core, placenta and outer pericarp were composed of homogeneously distributed cells, the structure of the locular tissue was atypical.
