鲜花的光学性质

本文采用反射光谱、荧光光谱、激发光谱研究了迎春花、紫红色芍药、大红月季和橙红月季的光生态。结果表明，不同的鲜花光生态有明显的差异，鲜花中的花青素和类胡萝卜素在紫外光、可见光的激发下发出荧光，使鲜花更加鲜艳靓丽。通过对鲜花光生态的讨论，揭示出阳光对花儿的影响与作用，为鲜花光生态膜的开发以及人工照明的应用提供一定的生态依据。

Optical Characteristics of Fresh Flowers

The optical ecology of fresh flowers are studied using the method of spectrum in this paper. The results show that the optical ecology of different flower has obvious difference. The carotenoid and anthocyanin of flowers can emit polychrome fluorescence excited by sunlight, and the fluorescence made the color of flowers more beautiful. The results reveal the sunlight's influences on flower, and provide the ecological basis for the exploitation of photoecology film and the application of artificial lighting in the cultivation of fresh flowers.
