ShareSummary
Magnetic resonance imaging (MRI) was used for the first time in the research of flower bud supercooling. Direct observation of living Camellia yuhsienensis buds through MRI and tissue browning tests showed that the freezing order of the flower organs is: bud axis, scale, petal, pistil and stamen. It is coincident with the direction of ice development from bud axes to flower organs upwards. The corresponding results from MRI and freezing-fixation showed that the water translocation from flower organs to axes and scales is carried on in the course of bud freezing.
