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光（NBL）诱导保护性栽培系统中作物的防御反应。在卷心菜（模式植物）和番茄中，我们将分析特别是短波长光子通量（UVB、UVA、Blue）是否可以触发对所选择的重要食草昆虫的抗性。波长、强度和照明模式等重要因素应进行优化。此外，我们想知道抗性诱导的功效是否取决于植物和食草动物物种，特别是害虫的不同进食策略（放牧与吮吸）。此外，可能的影响，更高的热带水平将被认为是研究寄生性搜索和寄生效果的诱导与非诱导植物。在描述和选择方便的系统（诱导方案、植物、害虫）后，将进行完整代谢组的首次初步分析，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.
