An inhibitor of ethylene signalling attenuates the enhancing effect of HC on ABA down-regulation. Levels of ABA (A) and ABA catabolites (B) were determined as described in Fig. 6 in HC- and NBD–HC-treated buds sampled 48h after treatment. Levels of VvNCED1 (C) and VvA8H-CYP707A4 (D) transcript were determined in the same bud samples as described in Fig. 3.
