FIGURE 1.

Four gibberellic acid (GA) inhibitors substantially reduced the growth of tef seedlings. Tef seedlings treated with different levels of chlormequat-Cl or CC (A), daminozide or DM (B), mepiquat-Cl, or MC (C), and paclobutrazol or PBZ (D). The length of shoots (E) and roots (F) of seedlings treated with different levels of the four GA inhibitors. PBZ treated plants partially recovered after transfer to medium with gibberellic acid (G). Shoot length (H), and root length (I) of plants that recovered from the PBZ effect. Arrows in (H,I) indicate the date of transfer to the GA medium. Means with different letters were significantly different from each other at p < 0.05.
