Chestnut ink disease, caused by root pathogens (Phytophthora sp. ), induces dieback and mortality in sweet chestnut, C. sativa. Classical biological control can be efficient using ink resistance rootstocks that block the entrance of the fungus.
In this context, selected ink-resistant chestnut clones need to be propagated massively. Here, a method is presented for multplication and rooting clones under photoautotrophic conditions.
Resins
The influence of silvicultural practices on resin production: stand density, tree diameter, and use of controlled fire
Some aspects contribute to the increase of resin tapping costs and, hence, to the reduction of resin yield, namely: the limitation on the diameter of the trees
