Basals emerge becos the axillary nodes down there no longer are affected by apical dominance. The apical point produces the plant hormone, auxin, that travels downwards and suppress axillary shoots frm growing if their concentration is sufficiently high. As the plant groes too tall, not enough auxin reaches the nodes down there, hence they grow out. Bending the plant also prevents auxin from reaching the lower nodes (though the effectiveness of this method depends on many factors), hence the emergence of basal. The surest way to produce basals is to kill apical dominance, whether by looping off the apical point or bending the vine to prevent translocation of auxin to the lower nodes.
