Summary

Low temperature breakdown (LTB) is a physiological disorder that can affect kiwifruit (Actinidia deliciosa cv Hayward) and some selections of Actinidia chinensis fruit after several months of cold storage. One of its symptoms manifests as the "grainy" appearance of the outer pericarp, followed by water-soaking associated with extreme softening of the fruit. Observation by light microscopy and SEM suggested that the "grainy" appearance of LTB-affected kiwifruit was associated with the presence of gas bubbles, occurring in some cells. Bulk porosity of the cell wall, determined using polyethylene glycol (PEG) of different molecular mass, decreased with increasing severity of the symptoms.
