A remarkable maize mutant, aberrant phyllotaxy1 (abph1) displays a decussate phyllotactic pattern (leaves are paired at 180[degrees] and the following leaf pair develops at a 90[degrees] angle) while wild type maize develops as distichous (alternating leaf initiation) plants.
14]C distribution studies showing preferential accumulation of radioactivity at the node of the labeled leaf (Stephenson and Wilson, 1977); however, the distribution of pods among the three nodes provides little support for the phyllotactic pattern of preferential distribution to alternate nodes described by Bloomquist and Kust (1971).
Fully causal models have not yet led to realistic visualizations, but phyllotactic arrangements of plant organs have been reproduced by models including descriptive terms.
