Conteúdo: | "Manila" mango trees reach heights and canopy diameters up to 20m at 15 years of age. Even though planting densities are low (50 trees ha-1)closing of canopies and crowding of foliage drastically reduces yield.On the other hand, phytosanitary protection and the harvest itself areexpensive operations. In order to reduce tree height of "Manila" mangotree some cultivars like "Irwin" (I), "Esmeralda" (E) and "Manila" (M), are being tested in several interstock/rootstock combinations. With the objective of studying the effect that such combinations have over the foliage growth, several growth indices were measured in the following treatments: M (seedling trees) M/I, M/M, M/M/M, M/E/I, M/I/I and M/E/M. Trees were evaluated when 9 years old during the mainvegetative flush of 1990. Results indicated that treatments M/I/I and M/E/M, which are among the more compacted combinations, showed the lowest relative growth rates (291.2, 204.3mg g-1 day1) as well as unit leaf rates (2921.7, 1968.7mg cm-2 day-1). No significant differences in leaf-area ratio were found between treatments.
