Abstract:
Weather conditions are well known to influence fruit development, quality and storage properties. To date, little attention has been paid to the potential information that the kiwifruit skin may provide about its growing environment. A new non-destructive technique, fringe projection, has been identified as a potential methodology to extract topographical data from fruit skins. In this work, topographical changes of Zespri 'SunGold™' (Actinidia chinensis) kiwifruit were mapped during development. Fruit were sampled at regular intervals (10-12 days) and then, following sampling, weight, skin colour, skin surface topography, and dry matter were determined. The resulting data enable mapping of skin topographical (and lenticel) changes during the development process. New understandings of the kiwifruit topography changes during development and potential implications are discussed.
