Summary: <\/em><\/strong>Phyllostachys pubesens <\/em>is much planted and adaptable to growing conditions in some mountainous regions of Cao Bang, Bac Kan and Thai Nguyen provinces. This research shows that the introduction of Phyllostachys pubesens <\/em>in Hoa Binh from Cao Bang is feasible and should be done. As Phyllostachys pubesens <\/em>has manifold value, attention must be paid to long- term and comprehensive research.<\/p>\n
