Fig. 5. Development of lateral shoots at the end of phase 1 (66 d), showing their length (narrow bars), number of unbranched phytomers (open portion of wide bars) and number of branched phytomers (solid portion of wide bars) at each phytomer position along the primary stolon of (A) plants permitted to form nodal roots (+R) and (B) plants prevented from doing so (–R). (Solid circles represent unemerged axillary buds at phytomers on the primary stolon.) Bars indicate s.e.m. (The first‐formed four large branches of the +R plants were not assessed at this time.)
