Different zones and the corresponding nodal position from which stem and axillary bud samples were harvested in Chrysanthemum C17 and C18.

For C17 in V1 nodal positions 37 to 31 (Zone A V1) were pooled together to represent inhibited axillary buds under apical dominance. Positions 26 to 16 in week 1 (Zone B V1) contain axillary buds that are further away from the shoot apex and show more outgrowth. Positions 13 to 8 (Zone C V1) represent bottom axillary buds inhibited by correlative inhibition of middle axillary buds. In T2 nodal positions 45 to 42 (Zone A T2) were pooled because the buds in this section showed the strongest outgrowth after T2 and release from apical dominance. Nodal positions 41 to 38 (Zone B T2) were pooled because these buds showed a diminishing outgrowth after week 2 when compared to the nodal positions above them. Nodal positions 37 to 31 (Zone C T2) were pooled to represent buds that show inhibited outgrowth after week 2. For C18 in V1 nodal positions 24–20 represent subapical inhibited buds (Zone A V1), positions 19–14 represent buds that are less inhibited by apical dominance (Zone B V1) and positions 13–8 represent buds furthest away from apical influence. In V2 positions 30–25 represent inhibited subapical buds (Zone A V2), positions 24–20 (Zone B’ V2) and 19–14 (Zone B” V2) represent less inhibited buds with zone B’ and B” the same positions as zone A and B in V1.
