Effect of Al exposure on the degree of cell wall methylation after 0, 24, 48 and 96 h
| Treatment time (h) | Degree of cell wall methylation (%) | ||
|---|---|---|---|
| 0 µm Al | 200 µm Al | 1000 µm Al | |
| 0 | 92 (±0.5) | 92 (±0.5) | 92 (±0.5) |
| 24 | 88 (±1.2) | 83 (±1.3) | 77 (±2.1) |
| 48 | 87 (±1.1) | 96 (±2.4) | 93 (±1.9) |
| 96 | 90 (±1.0) | 94 (±2.2) | 97 (±4.3) |
Values are the arithmetic mean (with the s.d.) of two experimental replicates (each replicate contains 300–400 apical root tips) and are expressed on a dry mass basis.
