Multiplicação do cafeeiro por estacas com uma fôlha

Abstract

A new method of propagation of the coffee plant by stem-cuttings has been developed. Single-node stem pieces with two opposite leaves were split longitudinally in two halves. These were treated by a hormone and rooted in a hot frame in washed sand. Stem pieces from orthotropic branches gave origin to normal plants, whereas cuttings from plagiotropic branches gave plants with only lateral branches. The one-leaf, stem-cuttings may be used advantageously in studies of bud mutation induced by colchicine or other methods. They are also of value in laboratory studies on the biology of insects which attack coffee leaves.
