Enhancement of defence potential of crop plants for insect pests by application of LED generated narrow bandwidth light (NBL)

该研究的目的是通过LED技术产生的额外窄带宽光（NBL）诱导保护栽培系统中作物植物的防御反应。在卷心菜（模式植物）和西红柿中，我们将分析特定的短波长光子通量（UVB， UVA, Blue）是否会引发对选定的重要食草昆虫的抗性。波长、强度和照明方式等重要因素应加以优化。此外，我们想知道抗性诱导的效果是否取决于植物和食草动物的种类，特别是不同的摄食策略（放牧还是吮吸）。此外，还将通过对诱导和非诱导植物的寄生蜂搜索和寄生效果的研究来考虑对更高热带水平的可能影响。在描述和选择方便的系统（诱导方案，植物，害虫）之后，将进行完全代谢的第一次试点分析，以表征与诱导过程相关的光诱导化合物。

Aim of the study is the induction of defence reactions in crop plants in protected cultivation systems by means of additional narrow bandwidth light (NBL) generated by LED technology. In cabbage (model plant) and tomato we will analyse whether in particular short wavelength photon fluxes (UVB, UVA, Blue) can trigger pant resistance to selected important herbivorous insects. Important factors such as wavelength, intensities and lighting pattern should be optimized. Moreover we want to know whether the efficacy of resistance induction depends on plant and herbivore species, in particular different feeding strategies (grazing vs sucking) of pests. Moreover possible effects on higher tropic levels will be considered by studies of parasitoids searching and parasitization efficacy on induced vs non-induced plants. After description and selection of convenient systems (induction scheme, plant, pest) first pilot analysis of the complete metabolom will be performed to characterize light induced compounds related to the induction process.
