Abstract: Kino veins and/or pockets are characteristic defects of some Eucalyptus species and have long been recognised as sources of degrade in eucalypt timber. In order to investigate the causes of kino vein formation, the short-term responses of Eucalyptus globulus and E. nitens to mechanical, chemical (2-choroethyl-phosphonic acid) and biological wounding treatments were examined. With the exception of the chemical treatment, the various wounding treatments did not consistently induce kino vein formation in either species. Instead, the new wound-associated wood and bark formed after wounding was characterized by the presence of dark extractives for both species. Although the dark extractives appeared macroscopically similar to that of kino, microscopic examinations showed the dark extractives to be formed in the less organized wound tissue and not in specialized kino veins. We suggest that the induction of tree exudates is part of a non-specific wound response and not necessarily induced as a direct host response to invasion by microbial pathogens and insects.
