Mathematical model studies of the comprehensive generation of major and minor phyllotactic patterns in plants with a predominant focus on orixate phyllotaxis
Fig 5
Phyllotactic patterns generated in computer simulations using DC1.
(A) Computer simulations using DC1 were performed under various settings of parameters G and η (101×101 conditions), and the patterns obtained are displayed according to the color legend shown in Fig 3. (B) The black and red dots indicate the absolute values of divergence angles of the tetrastichous alternate patterns generated in (A) and real orixate phyllotaxis observed for winter buds of O. japonica (data of P1~P2 and P2~P3 in Fig 4D), respectively. The blue dots show the averages determined from the real data of P1~P2 to P6~P7 (Fig 4D) for each winter bud of O. japonica. In this panel, alternate patterns with a four-cycle change in divergence angles in the sequence of p, q, −p, and −q (|p|>|q|) were plotted at the point (|p|,|q|). (C) An example of the tetrastichous alternate patterns, which was produced by computer simulation at G = 0.3 and η = 1.5. This pattern has a divergence angle change in the sequence of 165°, −91°, −165°, and 91° and, unlike orixate phyllotaxis, exhibits a distorted tetrastichy, rather than an orthogonal tetrastichy.
