叶片形状的生长算法模型
Growth-Algorithm Model of Leaf Shape
摘要：
植物叶子的无数形状对生物物理理论的解释力提出了挑战。需要一个模型，可以产生这些形状与一个小的参数集。本文提出了一个简单的模型，叶片形状的基础上的生长算法，它管理的生长速度在两个维度上的叶片组织，因此叶片的轮廓。叶片的生长受叶脉位置的控制。该模型给出了一个近似的各种高等植物叶的形状。在密切相关的植物中发现的叶片形状的变化进行了讨论的增长算法的变化。该模型可以扩展到更复杂的叶类型。
英文摘要：
The innumerable shapes of plant leaves present a challenge to the explanatory power of biophysical theory. A model is needed that can produce these shapes with a small set of parameters. This paper presents a simple model of leaf shape based on a growth algorithm, which governs the growth rate of leaf tissue in two dimensions and hence the outline of the leaf. The growth of leaf lobes is governed by the position of leaf veins. This model gives an approximation to a wide variety of higher plant leaf shapes. The variation of leaf shapes found in closely related plants is discussed in terms of variability in the growth algorithms. The model can be extended to more complex leaf types.
