Abstract

ONO, E.O.; RODRIGUES, J.D.  and  PINHO, S.Z. do. Interactions between auxins and boric acid in the rooting of stem cuttings Coffea arabica L. cv. "Mundo Novo". Sci. agric. (Piracicaba, Braz.) [online]. 1992, vol.49, n.spe, pp. 23-27. ISSN 0103-9016.  http://dx.doi.org/10.1590/S0103-90161992000400005.

The present research had as purpose to study auxin and boron effects on rooting of Coffea arábica L. cv. "Mundo Novo" stem cuttings. The cuttings were taken from orthotropous semi-hardwood branches of coffee-tree, which were treated during 24 hours with IBA or NAA and boron solutions, and the mixture of the three substances, resulting a total of 14 treatments. The following observations were realized, taking the cuttings 90 days after planting: number of rooted cuttings and "callus" formation per cutting. It can be concluded that to obtain a higher number of rooted cuttings, the treatment with NAA at 100 or 200 ppm plus boron is the most suitable.
