Abstract

Callus cells of pear (Pyrus communis cv. 'Bartlett') underwent lethal cellular senescence in response to grafting with callus cells of quince (Cydonia oblonga cv. 'Van Deman'). Similar responses occurred when the cells were in direct contact and when they were separated by a porous membrane filter. These results indicate that direct cellular contact is not necessary to elicit graft incompatibility between pear and quince.
