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.
