Leaf Arrangement (Phyllotactic) Patterns Generated by Computer Simulations (VIDEO)
Caption
Researchers at the University of Tokyo used the Expanded Douady and Couder 2 equation to model how leaves are arranged on plant stems. In the new equation, each leaf more intensely inhibits the formation of other leaves nearby as it grows older. The video shows a top-down view of leaf arrangement patterns as new leaves (red semicircles) form from the shoot apex (central black circle) and grow outwards. The inhibitory field is represented as a contour map, where red represents strongest inhibitory strength and blue represents weakest inhibitory strength.
