RESULT OF RESEARCH ON CUTTING PROPAGATION FOR ALNUS NEPALENSIA

Abstract

Alnus nepalensia is the fast growing tree specie which is used for supply materials for
producing sawn timber, pulpwood, or materials for planting mushroom. Alnus nepalensia is
also planted in belt for fire resistance or being shade trees for non-timber species.
The experiment of cutting Alnus nepalensis was conducted in 2008-2009 in Ba Vi, Ha Noi.
The results show that it is suitatble to propagate this specie in the yellow sandy substratum in
Summer or Autumn. Using braches, cutting on the tops of branches for propragating is
appopriate. Treating cuttings by NAA (1.0-1.5%) can give us the highest rate of sprout root.
Each 1-2 hours, watering one time and each time watering in 10 seconds. The rate of sprout
root in this experiment is quite high, reaching from 56.7-60%.
