An experiment was conducted on the effect of different vegetative propagation techniques (rhizome cutting, offset cuttings, culm cuttings, branch cutting, and culm layering) of Arundinaria alpine to find out the best propagation technique for establishing A. alpine plantation. Randomized complete block design with three replications was used. The experiment was established at Hagereselam, southern Ethiopia, in April 1998 and necessary data collected in December 1998. A highly significant difference was detected (P0.01) among treatments. Offset cutting showed better performance than the rest with regard to shooting and rooting characteristics (about 21 root with 0.6 m length and tallest shoot about 2 m in height and 82% survival), followed by culms cutting (18.5% survival) and culms layering (14.5% survival) methods, respectively. Branch cutting and rhizome cutting methods showed poor survival (P0.01). The present study may indicate the possibility to develop A. alpine plantation from vegetative propagation techniques. Further investigation on the biological factors that hampers root and shoot initiations in using branch cutting and rhizome cutting methods is also recommended.
