Abstract

This study provides experimental data on rosebush to extend the auxin-based FSPM model of bud outgrowth to account for sugar roles. The analysis of the relationship between sugar availability and bud outgrowth at both plant and bud scales showed that sugar availability is able to decrease apical dominance by reducing the lag time before bud outgrowth.
