Abstract:
Physiological pitting in 'Hayward' kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson) develops during low temperature storage and is manifest as discrete sunken pits visible on the surface of the fruit. A number of surveys were carried out to determine whether fruit mineral and dry-matter concentrations were associated with the incidence of this disorder. High pitting incidence was generally associated with low Ca and Mg, and high P and K concentrations, and low dry matter in the fruit. However, these relationships were not always found, and analysis of the variability of these fruit properties within vines, between vines and between orchards suggests that true relationships between pitting and fruit properties can be masked by inappropriate sampling methods, an inadequate range of disorder incidence, and the effects of vine management and environment.
