Table I.
PG and CT concentration in leaf lamina before and 24 h after wounding
| Treatment | PGs | CTsa |
|---|---|---|
| mg g dry wt−1 | ||
| Control | 96 ± 3.0 | 3.2 ± 0.4 |
| Wounded | 105 ± 10.0 | 4.1 ± 0.1 |
PG and CT levels from leaves eight through 10 of control or wounded plants were analyzed as described in “Materials and Methods.” Values are means ± sd (n = 3 individual plants). The experiment was repeated with another aspen clone with equivalent results.
a
CT levels before and after wounding differed significantly (Student's t test, P < 0.01).
