“…These measurements may also aid in the important task of defi ning optimum plant densities for each rootstock/scion combination (Galán Saúco, 1997a). Perez et al (1988) measured mango yield effi ciency in terms of canopy volume, and found that effi ciency decreased as trees grew older and larger. This is not surprising for a terminal bearing species where the surface area to vol ume ratio decreases as tree size increases.…”

Low yields and high harvesting costs are long-standing problems in mango (Mangifera indica L.) cultivation. In an effort to increase productivity in the scion 'Kensington Pride' we examined the impact of nine different rootstocks over a 10-year period. Rootstock effects on fruit production were significant in most seasons, and cumulative yields (nine seasons of cropping) for the best treatment ('Sg. Siput') exceeded those of the poorest treatment ('Sabre') by 141%. Yield efficiencies (expressed on both a trunk cross-sectional area and canopy silhouette area basis) were also significantly affected by rootstock. Rootstock effects on yield and yield efficiency were generally consistent across seasons, despite large seasonal variations in yield. Harvest rates were also influenced by rootstock, and were poorly correlated with tree size. These results demonstrate possibilities for manipulating mango scion productivity through rootstock genotype.

Can the productivity of mango orchards be increased by using high-density plantings?

a b s t r a c tMango (Mangifera indica) trees are traditionally established at about 100-200 trees per ha and eventually grow into large specimens 10 m tall or more, making spraying and harvesting difficult. It also takes a long time to recover the initial costs of establishing and maintaining the orchard. There has been considerable interest in planting orchards up to 4000 trees per ha to take advantage of early production and to increase economic returns. However, trees planted at high density soon begin to crowd and shade each other and production falls. We reviewed the performance of high-density orchards in different growing areas, and the role of dwarfing cultivars and rootstocks, tree canopy management and the growth regulator, paclobutrazol to control tree growth. There has been no general agreement on the optimum planting density for commercial orchards which vary from 200-4000 trees per ha in different experiments. Some potential dwarfing material has been developed in India and elsewhere, but these cultivars and rootstocks have not been widely integrated into high-density orchards. Canopy management needs to take into account the effect of pruning on the regrowth of the shoots and branches, light distribution through the canopy and the loss of the leaves that support the developing crop. Pruning must also take into account the effect of vegetative growth on flower initiation. Annual light pruning usually provides better fruit production than more severe pruning conducted less regularly. There have only been a few cases where it has been demonstrated that paclobutrazol can counteract the negative effect of pruning on flowering and fruit production. There are also concerns with residues of this chemical in export markets and contamination of ground waters. The future development of high-density plantings in this crop is dependent on the use of dwarfing cultivars and/or rootstocks and better canopy management strategies. Dwarfing cultivars and rootstocks should provide small-to medium-sized trees with medium to large yields. This can readily be identified in experiments by examining the relationship between yield and tree growth. Research on canopy management should assess the impact of pruning on flowering, light distribution within the canopy and the leaf area supporting the developing crop. The productivity of mango is not likely to be increased by the use of high-density plantings without extensive efforts in plant breeding and canopy management.Crown

Estudou-se o efeito da introdução de filtros, com duas dimensões (15 e 30cm), de três variedades de mangueiras (Coquinho, Carlota e Imperial) e duas alturas de enxertia (25 e 55cm), na var. Tommy-Atkins, enxertada na var. Espada. Os resultados mostraram que os tratamentos não afetaram o desenvolvimento vegetativo das mangueiras, avaliados após seis anos de implantação do experimento, através dos parâmetros: perímetro do porta-enxerto e filtro, altura e diâmetro da copa. As produções de frutos analisadas após quatro colheitas, embora acusassem certa variação entre os tratamentos, não foram estatisticamente significantes.
A field study was carried out to determine the effects of two types of interstock incision (15 and 30cm lenght) using three Mango varieties (Coquinho, Carlota and Imperial). The effects were also determined using two grafting heights (25 and 55cm) with the var. Tommy Atkins grafted on var. Espada. The results indicated that the treatments did not show any impact on the vegetative growth, rootstock and interstock perimeters, height and diameter of the tree crown, measured six years after incision. The fruit production analised after four harvest seasons, showed certain variation among treatments; they were, however, not statistically significant
