Table 2.
Biomass, lignin amount, and lignin composition of WT P. trichocarpa trees grown in the greenhouse and at 3 different field locations in North Carolina (USA).
Biomass (g) | Lignin amount (%) | Lignin composition (S/G ratio) | |
---|---|---|---|
WT (greenhouse) | n.a. | 22.0 ± n.a. | 2.5 ± n.a. |
WT (field, Piedmont site) | 93.8 ± 9.2 | 26.4 ± 0.4 | 1.7 ± 0.1 |
WT (field, coastal plain site) | 136.1 ± 14.0 | 25.5 ± 0.5 | 1.9 ± 0.1 |
WT (field, mountain site) | 1088.9 ± 88.5 | 23.4 ± 0.3 | 2.0 ± 0.0 |
In the field, the trees were planted in April 2009, coppiced for the first time in January 2010, and coppiced for the second time in January 2011. Values (means ± standard error) are given for plant material derived from the greenhouse or the second coppice in the field. n.a., not available.
