Assessment of growth, development, and wood fiber length of transgenic eucalyptus hybrid clones
Keywords:
EcHB1 gene, eucalyptus hybrid,, growth,, wood fiber lengthAbstract
The gene EcHB1, is isolated from E. camaldulensis, encoding for
increasing the wood fiber length. In the period of 2010 - 2015, the gene was
transferred into superior clones of E. urophylla E. urophylla (UU hybrid)
via Agrobacterium tumefaciens. The field test for thế clones were planted at
Bavi (Hanoi) in 2018. This study evaluated the growth (height and breast
diameter) and fiber length traits of transformed clones at 21 months stage.
The results illustrated that some eucalypt transgenic clones showed good
performance in growth (DHB upto 6.0 cm and height ranged from 7.1 m to
7.8 m) and had higher wood fiber length (atleast 10% excceded) than that
in the control clones (UU89). Several potential clones showing fast
growing and long fiber length were selected for further assessments.
