摘　　要：植物叶形受环境调控产生显著差异的现象称为"异形叶(heterophylly)",它是研究植物环境适应性的理想模型。异形叶植物能够通过表型、结构和生理变化来适应不同环境,具有独特的研究价值。研究表明,异形叶与环境因子和植物激素密切相关,这一事件可能经过多次独立演化,其调控机制也各有不同。本文将对现有的异形叶研究进行系统综述,为阐明植物的环境适应机制提供参考。Plants show amazing morphological differences in leaf form in response to changes in the surrounding environment, which is a phenomenon called heterophylly. Heterophylly provides an ideal process to understand mechanisms by which plants adapt their growth to withstand environmental changes. Heterophyllous plants can adapt to different environments through phenotypic, structural and physiological changes, which have unique research value. Studies show that heterophylly are correlated with environmental changes as well as phytohormones. Heterophylly has evolved multiple times independently during plant evolution and the mechanism of each seems to be different. This event may have undergone several independent evolutions, and its regulatory mechanisms are different. In this paper, we systematically reviewed previous studies on heterophylly and provided a reference for the mechanism of environmental adaptation in plants.
