| Abstract: | The volume and straightness of stem were used as the main indexes for selection of superior trees of Betula alnoides.Three pieces of superior stands and 153 candidate trees were selected from the natural forests in Baise,Guangxi and 9 superior trees were selected for the seed collection.The measurements showed that the 6-year old progeny trees had average height of 12.8 m and average diameter of 14.0 cm,which still keep the superior properties of mother trees. |
