Development of all axillary shoots was investigated using tillering cultivars (delegated by cv. Longfellow) and no-tillering cultivars (delegated by cv. Yellow Dent) in maize. There was a buttress or axillary bud with only prophyll at the axil just above the topmost fertile ear node in both cultivars (Figs. 1, 2), but this did not develop any more (Fig. 3). Axillary buds differentiated acropetally, but ultimately the upper the node, the more the shoot developed exclusive on the tillers from lower nodes (Fig. 4). When shoot apex turned into reproductive stage (33 and 34 days after planting in Longfellow and Yellow Dent, respectively), the apices of upper axillary buds developed more rapidly than those of the lower buds, and initiation of young head occurred basipetally exclusive of the tillers which elongated at earlier stage (Tables. 1, 2). In vegetative stage, there was a similarity between Longfellow and Yellow Dent in respect to development of axillary buds. In Longfellow, lower buds developed into tillers, the shoot apices of them were tassel in the lower tillers, androgynous with both staminate and pistillate spikelets in the middling tillers (Table 1). Axillary buds at upper nodes than 5 formed ear, the upper the node, the longer their length exclusive of. the tillers (Table 1). In Yellow Dent, when shoot apex initiated inflorescence, the development of lower axillary buds (node 2-6) became slow and died during vegetative stage (Table 2). The inflorescence upper than node 6 was female, the upper the node, the longer their length (Table 2). Each secondary shoot produced tertiary shoots. The relation between secondary and tertiary shoots resembled to the relation between primary and secondary shoots.
