Of the “serious” pome fruit producers, South Africa, together with Brazil, have the production areas closest to the equator. This means higher summer temperatures and generally just altogether more plant stress and more fruit downgraded for processing compared to our major competitors. The great inefficiency of caring for fruit that ultimately ends up in a juice bin would have seriously endangered deciduous fruit production in South Africa if not for the (for now) favourable exchange rate. It shouldn’t be surprising that research under this theme is predominantly aimed at decreasing sunburn and internal fruit quality defects brought about by photothermal stress.
