ALMENARES GARLOBO, Guillermo R et al. Characterization of the vegetative development and its relationship with fruiting and production of orange trees [Citrus sinensis (L.) Osbeck]. cultrop [online]. 2015, vol.36, n.2, pp. 56-61. ISSN 1819-4087.
A characterization of the vegetative development of `Valencia Late´ and `Washington Navel` orange cultivars was done and the relationship between vegetative development, fruiting, production and efficiency of the fruiting and production was determined. A plot from each cultivar was selected and during every year’s flushing period, the number of leaves per canopy surface, tree dimensions and average foliar surface were evaluated; accumulated rainfall was recorded. Variables like vegetative development, foliar area per tree, foliar area per canopy volume and the foliar area index were estimated. From each variable data, a simple classification analysis of variance was performed every year. Variables as fruiting, production and efficiency of the fruiting and production were calculated and their relationship with those of vegetative development was determined through an Analysis of Canonic Correlations. The results showed that the vegetative development corresponds to the behavior of accumulated annual rainfall, as they increase, the vegetative development is higher. The foliar area was directly related to fruiting and production of both cultivars. Increased foliar area per tree and foliar area reduction per canopy volume mainly contributed to an increased fruiting (number of fruits per tree) and production (kg of fruits per tree)
