Table I.
Plant height (Hplant), stem basal diameter (∅s), number of leaves (Nleaves), internodal length (Linternode), and whole-plant leaf surface area (AL) as measured in plants of three lines of tobacco
SR1, Wild type; PG7 and PG16 correspond to two increasing levels of expression of the gene AnPGII. Means are reported ±sd (n = 12). Different letters indicate significant differences (P < 0.05).
| Hplant, cm (P < 0.001) | ∅s, mm (n.s.) | Nleaves (n.s.) | Linternode, cm (P = 0.006) | AL, m2 (P = 0.048) | |
