Compositional changes in kiwifruit infected with Botrytis cinerea 2. In vitro studies

Abstract

Growth of Botrytis cinerea on sterilised kiwifruit (Actinidia deliciosa (A. Chev.) CF. Liang et A.R. Ferguson) cv. Hayward juice, showed that in vitro the fungus used glucose in preference to fructose as a carbon source. In addition, it metabolised citric, quinic, and malic acids as carbon sources. However, it was not able to utilise oxalic acid. Fumaric acid was the only acid to increase in the culture medium during growth of the fungus.
