Abstract

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.
