Kinetics of pedicel and petiole abscission in the KD1 semidominant mutant Pts. Pedicel (A) or petiole (B) abscission assays compared wild-type (cv VF36) plants with plants of the Pts mutant. The percentages of pedicel and petiole abscission were determined at intervals after flower removal or during ethylene treatment (3 μL L−1), respectively. Different letters indicate significant differences (Student’s t test, P < 0.05). Results are the means of three replicates ± sd, with at least 15 samples per replicate.
