The research results indicated that: The average number of knots in veneer sheet measured for each species tends to decrease with increasing age. The older E. urophylla plantations produced veneer with the least number of average knots, followed by A. mangium and then Acacia hybrid. Acacia hybrid produced higher levels of large knots (> 3 cm) compared to the other species investigated. The average number of end splits for the acacia species reduced with age but progressively increased with age for E. urophylla. | External characterisation of peeled veneer from some plantation species in Vietnam
