Pruning period and wound treatment on hardwoods

Abstract

The pruning times, and the behaviour and comparative effectiveness of four pruning protection products available on the French market for broadleaved species, were monitored over a period of three years. The research on the influence of pruning times was carried out on beech and wild cherry, whilst the effect of product treatment was conducted on wild cherry alone. At the end of the third and final year of experimentation, internal infection of the wood and the characterisation of any present or absent pathogens was monitored in the majority of pruned specimens taken from all four sites after felling, with samples being taken for laboratory analysis from those regions where the wood exhibited any changes.
