Summary

Cryo-scanning electron microscopy (SEM) of stems of cut flowering roses held in water for 2 days indicated the presence of an amorphous substance (bacterial slime). Previous research showed that this bacterial slime dissolved during dehydration during conventional SEM. A similar result has been found in rose stems. Previous studies have perhaps underestimated its role in the vascular blockage of cut rose stems. Cryo-ultramilling permitted observation of the action of bacteria in vascular blockage. However, this behaviour is not yet well defined.
