LIGARRETO-MORENO, Gustavo Adolfo; TORRES-APONTE, Walter Smith  and  ARIZA-CASTILLO, César Alfonso. Propagation of the neotropical fruit Vaccinium meridionale Swartz by air layering. Agron. colomb. [online]. 2013, vol.31, n.2, pp.169-175. ISSN 0120-9965.

Vaccinium meridionale Swartz has its natural distribution in the tropics of the New World, from 2,100 to 4,000 m a.s.l.; and is a keystone species in habitat conservation, with 3 m high shrubs when pruned. The aim of this study was to evaluate stem rooting using naphthaleneacetic acid (NAA ) and Aloe vera as rooting promoters with a farm propagation system. For this purpose, a natural population of plants was selected in San Miguel de Sema (Boyaca, Colombia), 5°31'15'' N and 73°43'39'' W, at 2,615 m a.s.l., with an average temperature of 13°C and an average annual precipitation of 1,000-1,300 mm. The results showed that the studied rooting promoters stimulated the appearance and development of roots; however, the NAA treatments had greater root growth over time. Developing air layers allowed for their separation from the mother plants and transplant 6 months after the application of the rooting promoters started
