Abstract: | Harvest index is defined and its relationship with primary production, biomass partitioning and yield components in forest trees examined. As stand density has been found to have a major effect on harvest index, it is concluded that further development of the harvest index concept in forest trees will need to take account of density-yield relationships. |
