A PREDISPOSING INFLUENCE OF PRUNING ON THE DEVELOPMENT OF BACTERIAL CANKER IN THE PEACH TREE AND ITS PROBABLE RELATION TO STEM WATER CONTENT IN WINTER |

| Abstract:
Inoculations with the bacterial canker agent performed on peach trees pruned in late autumn led to a more widespread infection during the winter than when performed on spring-pruned trees. Stem water content was also higher in winter. It has previously been established that a higher peach stem water content enabled bacterial canker to develop to a greater extent. It is assumed that the effect of autumn pruning, which was seen here to predispose trees to bacterial canker, is related to the increase in stem water content in winter. | |
