  1. Wood qualities and growth traits were analyzed using four-year-old WT and transgenic lines. OE2~OE4 indicate 35S::BpCCR1#OE2~35S::BpCCR1#OE4. Different letters indicate significant differences between WT, OE2 and br in Duncan-test (P < 0.05). Values are mean ± standard error of three measurements from two individual plants per line
