摘　要：

基于生态学和能量角度, 早期对增强UV-B辐射影响植物生长发育及光合能力的报道多为负面性报道, 例如, 损伤DNA、改变蛋白质结构; 增加活性氧及细胞膜透性; 破坏光合作用; 使植株矮化、株型缩小, 抑制生长等。然而, UV-B并不是只对植物有不利影响, 特别是在设施内UV-B不足或缺乏的情况下, 适量补充反而有利于作物体内修复机制的激活, 表现出对生长、产量和品质的正向调控。本文综述了设施栽培作物的信号转导、次生代谢物质、光合能力、生长发育、果实品质及产量等响应UV-B的研究进展, 以期为设施栽培生产中UV-B的合理利用提供参考。

Abstract:

There are some negative reports about effects of UV-B on growth, development and photosynthetic capacity based on the point of ecology and energy previously, for example, damaging DNA, protein structure, increasing ROS and cell membrane permeability, destroying photosynthesis, and inhibiting stem length, canopy and stretch, etc. However, UV-B not only have adverse effects on the plant, it is also benefit to activity repair mechanisms of plant especially for case of insufficient or lacking UV-B in greenhouse, and showing positive regulation on growth, yield and quality. In this review, the research of single transduction, secondary metabolites, photosynthetic capacity, growth and development, fruit quality and yield of plant in greenhouse response to UV-B were summarized, which will serve as the reference for rational utilization of UV-B in greenhouse production.

Key words: UV-B; protected culture; photosynthetic capacity; signal transduction; growth and development
