PADILLA-VEGA, José; JIMENEZ OSORNIO, Juan José  e  ESTRADA MEDINA, Héctor. Analysis of vegetation structure of fruit orchards from southern Yucatan, Mexico. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.7, pp.1443-1454. ISSN 2007-0934.

The aim of this study was to know the tree structure of the irrigation unit, whose area is 65 hectares divided into 65 plots of 10 000 m² each, in which a sample of 180 m² per plot was performed. 1565 individuals which belong to 40 species, 28 genera and 19 families, were recorded; its horizontal distribution is divided into four canopies, the highest covered species such as Cocos nucifera, Manilkara zapota and Cedrela odorata with heights ranging from 9 to 10 m. The results from structural indices place Sabal yapa and Citrus sinensis as the most important species. Five uses of land were recognized of which the highest value obtained in diversity were obtained by agroforestry plots. The irrigation unit is divided into different agroforestry systems and each one of them has different species which gives them a unique structure.
