SANCHEZ BUITRAGO, José Alejandro  and  SILVA HERRERA, Luis Jairo. Silvicultural study of Sapindus saponaria L. (Jaboncillo), as foundation for its silvo-industrial use. Colomb. for. [online]. 2008, vol.11, n.1, pp.71-81. ISSN 0120-0739.

A silvicultural study of Sapindus saponaria L. was carried out including sexual and asexual propagation tests, provenance test, phenological surveillance, and quantification of fruits production. The sexual propagation test was carried out using five source localities, being the best those seeds from Santa Cruz (Bolivia). The asexual propagation test had a negative result because the cuttings did not root, making it necessary to try different methods for asexual reproduction. The seedlings obtained from the sexual propagation test were used to establish a plantation in Otanche (Boyacá) in order to evaluate growth and mortality. After five months, the highest growth was found in those seeds from Santa Cruz (Bolivia). However, this result was not significant from a statistical point of view. The best results regarding mortality came from the seeds from Viotá (Cundinamarca), while those from Palmira (Valle) showed the highest levels of mortality. Fruit production was measured and related to the DBH and the canopy wide. Flowering and fruiting periods as well as the harvest season of the fruits in Viotá (Cundinamarca) were established. Some methods for fruit harvesting and planting of the species are proposed.
