Sucrose addition rapidly initiates bud release and suppresses the branching repressor, BRC1. (A) Sucrose feeding via the nodes 3 and 5 petioles rapidly initiated bud release of intact plants. (B) Sucrose feeding via the node 3 petiole rescued the delayed bud release of plants decapitated low on the stem; n = 4. (C) BRC1 expression in node 2 buds was inhibited within 2 h by both decapitation and sucrose supply to intact plants (P ≤ 0.05). Twenty buds were collected per replicate, n = 3. *Statistical difference from controls (P ≤ 0.05) based on a two-tailed t test. All data are mean ± SEM.
