Table IV.
Frequency of free phenolic groups in G or S units involved in β-O-4 bonds, as shown from thioacidolyses of methylated extract-free poplars
| Line | Age | G with Free Phenol | S with Free Phenol |
|---|---|---|---|
| % molar | |||
| ASCAD52 | 2 years | 30.5 | 3.5 |
| ASCAD21 | 2 years | 33.6 | 4.5 |
| 6 months | 32 | 4.5 | |
| SCAD1 | 2 years | 29.8 | 3.6 |
| 6 months | 29.4 | 3.6 | |
| Control | 2 years | 26.4 | 3.0 |
| 6 months | 25.7 | 2.8 | |
| ASOMT10B | 1 year | 21.5 | 2.6 |
| ASCAD21 × ASOMT7 | 6 months | 25.9 | 2.6 |
For each line, measurements were done from one (6-month-old poplars) or three to five (older poplars gathered for analyses) plants.
