Summary

The physical state of water and metabolic activity in tulip bulbs held at low temperatures were observed using H-nuclear magnetic resonance imaging (by the Laboratory of Horticultural Science, Japan) and tetranitro blue tetrazolium staining. A strong water signal was observed in cortex parenchyma for bulb scales held at 15 deg C for 3 weeks, followed by storage at 5 deg C for 8 weeks, while a weak water signal was recorded in non-chilled bulb scales. Signal intensity and nuclear magnetic resonance longitudinal relaxation time for tulip bulbs reflected differences in the degree of water binding and metabolic activity between chilled and non-chilled bulbs.
