Figure 7.

Synergistic effect of adenine and DF on growth inhibition of Arabidopsis seedlings. Protocol as described in the legend to Figure 2, except that the agar medium received no supplement (top row), or was supplemented with 150 nm DF (second row), 250 μm adenine (third row), or 150 nm DF and 250 μm adenine (bottom row). Seedling wet weights (mean ± sd, n = 6) following root excision are listed at the right. *, P < 0.05 when compared to all other conditions in unpaired two-tailed t tests. Seedlings shown represent those closest to the average for the group.
