Abstract
In long-term, large-scale avocado rootstock-scion research, the effect of rootstock on tree vigor and size was evaluated.
Tree size was calculated from aerial photography as the projected area of the canopies.
This method also enabled yield per unit land area to be calculated.
In some cases, the trunk circumference was measured and correlated with the canopy projected area.
During 1972–1990, about 150,000 trees, involved in about 700 field experiments, were measured by this method.
As a result of this follow-up, it can be concluded, that avocado rootstock affect tree vigor and size to a considerable and significant extent.
From the economical point of view, the reduction of tree size could result in either increased or decreased yield per unit area.
Furthermore, the, dwarfing rootstocks selected in this research are restricted to certain combinations of soil factors, like any other rootstock, and could not be recommended for use everywhere.
