生长在热带雨林低光环境中的林木植被部分叶片表面呈现蓝晕色表型。这种蓝晕色表型由叶片表皮附近多种相同或相异的微结构所引起。各种微结构是植被适应低光生长环境而长期进化的产物。它通过改变植物组织内部反射光的物理特性,在增强光合活性光吸收的同时产生蓝晕色或其它周期性变化的复合色,从而形成植物结构色表型。结构色的存在在植物生长发育过程中起到关键作用。本文综述了植物结构色产生的机制以及生物学功能。
The growth of part of the foliage in the forest vegetation in the low light environment of tropical rainforest presents a bluish halo phenotype. This bluish halo phenotype is caused by a number of identical or dissimilar microstructures near the epidermis of leaves. Various microstructures are the product of long-term evolution of vegetation adapted to low-light-growth environments. By changing the physical characteristics of the reflected light inside the plant tissue, it can produce the blue color or other periodic complex color while enhancing the light absorption of the photosynthetic activity to form the plant structure color phenotype. The existence of structural color plays a key role in the process of plant growth and development. This review summarizes the mechanism of plant structural color generation and its biological functions.
