中文摘要：
综述了8个世纪以来，人类在研究叶序现象的发生规律和机制方面所取得的主要成就。植物的叶序一般符合斐波纳契序列，并存在黄金分割关系；互生叶序的发散角大多恒定；发散角可以采用多种数学方法进行推导；发散角的形成在光照利用方面具有一定的生态学意义；叶序在形态发生学上具有特定的规律，并与某些植物激素和遗传基因有关，同时植物叶序与其它形态特征之间也具有一定的相关性。
英文摘要：
The main achievements made in the field of the study on phyllotaxis for eight centuries are reviewed in terms of its regularity and morphogenesis mechanism, Phyllotaxis usually accords with the Fibonacci sequence and satisfies the relationship of the golden section mathematically. The angle of divergence usually is a constant, and can be deduced by means of different mathematical methods. The formation of constant divergence angle might be of certain ecological significance in utilizing light. The morphogenesis of phyllotaxis follows some particular regularity, and is related to some hormones and genes. The characteristics of phyllotaxis are also related to some other morphological features.
