光照对植物合成花色素苷的影响研究进展

Effects of Light on Anthocyanin Synthesis in Plants

花色素苷决定着花卉、果实及彩叶植物叶片的颜色,对植物的观赏性有着重要价值,已受到人们的广泛关注。近几年来,对于外界环境影响植物花色素苷合成的研究已有相关报道,但都是一些综合性的阐述。对于光照影响植物花色素苷的研究,缺乏更为系统和深入的论述。依据国内外近几年的相关文献,在阐述植物花色素苷合成机理的基础上,针对光照这一外界环境因子,综述了光照时间、不同光质及光照强度对于植物花色素苷合成的影响。指出了对于一般植物,光照时间越长,越有利于其合成花色素苷;在不同的光质中,对合成花色素苷最有效的是蓝光和紫外光;对于一般植物,光照强度越大,越有利于合成花色素苷。还分析了目前关于植物花色素苷研究尚存在的问题,并展望了今后的研究方向,以期为今后的研究提供一些参考。

Anthocyanin decides the color of fruits, flowers and the leaf of colored-leaf plants, it has attracted wide attention by its important value on the ornamental plant. There are some comprehensive descriptions of the environmental factors＇ influence on anthocyanin synthesis in recent years, but a more systematic and in-depth discussion for the light effects on anthocyanin is still lacking. Based on the relative literatures in recent years and the mechanism of anthocyanin synthesis in plant, the paper reviews the effect of illumination time, different light quality and light intensity on plant anthocyanin synthesis. The results show that： longer illumination time, stronger illumination intensity and blue and ultraviolet light are favorable and effective to the biosynthesis, stabilization and accumulation of anthocyanins in most of plants. This paper also analyzes the problems unsolved in this field, some suggestions about further researches on anthocyanin are put forward.
