Abstract
Prior to inoculation with a spore suspension of Botrytis cinerea, detached mature grape berries were given treatments to disrupt the epicuticular wax; gently rubbing with a rounded spatula, rubbing with a tissue, dipping in chloroform for 10 sec., or wounding with a scalpel. Other berries were inoculated at undisturbed areas on the side of the berry and at the base of the pedicle, or at the base of a pedicle with a natural wound. Berries were incubated at 23°C with 99% relative humidity for 72 hours, then evaluated for infection. Berries of Vitis vinifera cultivars `Thompson Seedless' and `Perlette' had infection rates of 18.5% and 3%, respectively, when the wax was undisturbed. Infection rates of berries with disrupted wax or natural wounds were much higher for both cultivars, ranging from 20% to 100%. No infections occured on either treated or untreated berries of cultivars derived from V. aestivalis, `Cynthiana'; V. labruscana, `Concord'; or those of hybrid origin, `Mars' and `Vignoles'. Wounding berries of `Concord' and `Cynthiana' resulted in 60% infection rates.
