QUIJADA, Osmar et al. Development and productivity of mango cultivars grafted over sinamaica rootstcks in the plain of Maracaibo. Agronomía Trop. [online]. 2008, vol.58, n.3, pp.207-213. ISSN 0002-192X.

The productive capacity of mango, Mangifera indica L. cultivars grafted over "Sinamaica" salinity tolerant rootstock was evaluated in order to determine adaptability to the agroecological conditions of the Maracaibo plain. Varia­bles studied were canopy lateral surface, canopy volume, number and weight of fruits per plant, fruit average weight, fructification index and productive efficiency. The statistical analysis showed significant differences (P<0.05) between cultivars for the studied variables. Cultivar Valencia Pride reached the highest values for canopy lateral surface and canopy volume, Criollo de Mara and Sensation showed the highest values of fruit yield per plant. Cultivars Criollo de Mara, Irwin and Manzana showed the highest values of fructification index and productive plant efficiency, while Haden, Springfels and Glenn had low values for these two variables. Results indicated that Criollo de Mara, Manzana and Sensation grafted over Sinamaica rootstock have the best adaptability to the agroecological conditions of the Maracaibo plain.
