Magnetic resonance imaging ( MRI ) is a non-destructive diagnostic method which has found more applications in medical field. However, it was felt conceivable to apply for monitoring various stages of sugar cane crop until it is harvested. MRI was employed to monitor changes in Magnetic Resonance ( MR ) intensities in stems of sugar cane which reflect on the increase in sucrose concentration. Contrast in MR images originates in the increase of sucrose concentration in the aqueous phase of the predominant parenchyma cells and T1 and T2 variations. MR images of sugar cane stems could provide valuable anatomical and chemical information as a function of growth. In mature stems mixed MR intensity patterns were observed both in transverse as well as longitudinal planes. We associate this due to the reflection of vascular bundles in ground parenchymatous cells which constitute 80 % of the sucrose storage. The results are discussed in the light of work on sugar assimilation and transport in Saccurum species.
