PRODUCTION OF WOOD AND GREEN BARK OF BLACK WATTLE (Acacia mearnsii De Wild) REGARDING TO SITE INDEX AND INITIAL SPACING

ABSTRACT

In the present study table yields for the production of wood and green bark of Acacia mearnsii were established. The data were obtained from permanent and temporary sample plots with different spacings distributed over the whole planting area of this species. The regression equations adjusted to this data showed an adjusted coefficient of determination superior to 0,98 and a low mean standard error. The results of the study are five yield tables classified by site index and initial spacing containing growth of dominant height, mean diameter, mean height, basal area, volume with or without bark per hectare, weight of green bark per hectare and mean annual volume increment with bark.

Key words:
yield; wood; bark; site; Acacia mearnsii
