摘要：

Basidiospore germination and germ-tube elongation in Crinipellis perniciosa, a fungal pathogen of cocoa, were inhibited by a range of procyanidins (condensed tannins) and monomeric flavan-3-ols. Dose/response studies revealed a strong trend of increasing anti-fungal potency with increasing molecular weight of the procyanidins tested. The non-ionic detergent Tween 20 inhibited the anti-fungal effects of procyanidin, suggesting that non-covalent complexes with fungal macromolecules may be responsible for these effects. © 1992.
