Figure 1.
Effect of flower removal (A) or leaf deblading and ethylene treatment (B) on the kinetics of pedicel and petiole abscission, respectively, in tomato explants. Flowers and leaves were excised as indicated in the schematic illustrations. The debladed-leaf explants held in vials with water were prepared as previously described for the flower explants (Meir et al., 2010), and exposed to ethylene (10 μL L−1 for 24 h). The percentage of accumulated pedicel or petiole abscission were monitored at the indicated time intervals following organ removal. The results are means of four replicates (n = 30 explants) ± SE.
