is a ubiquitous necrotrophic pathogen causing grey mould in economically important crops. Light effect in horticulture is undeniable and fungi also react to light. Selected specific light-emitting diodes (LEDs) and photoperiods can be used for fungal pathogen inhibition. This study aimed to evaluate how LED light wavelengths and photoperiods affect the growth parameters of . The morphological (mycelium appearance, sclerotia distribution) and phenotypic (conidia presence and size, mycelium growth rate, recovery) characteristics of the fungal pathogen were evaluated under royal blue 455 nm, blue 470 nm, cyan 505 nm, yellow 590 nm, and red 627 nm LED lights at various photoperiods (4, 8, 12, 16, 20, 24 h). The results revealed that the light conditions and photoperiods influenced the morphological and phenotypic characteristics. Overall, the highest inhibition was under yellow (590 nm) LED light at 4 and 8 h photoperiods. Conidia did not form under blue 455 nm at 8, 16, 20, and 24 h photoperiods. Therefore, it can be assumed that the phenotypic and morphological features of depend on the specific photoperiod and LED light wavelength. The results allowed an exploration of original research approaches, raised new scientific questions for further investigation, and suggested new green plant protection solutions.
是一种普遍存在的坏死营养型病原菌，可在经济作物上引起灰霉病。园艺中的光照影响不可否认，真菌也会对光作出反应。选定的特定发光二极管（LED）和光周期可用于抑制真菌病原体。本研究旨在评估LED光波长和光周期如何影响……的生长参数。在455nm皇家蓝、470nm蓝色、505nm青色、590nm黄色和627nm红色LED灯下，于不同光周期（4、8、12、16、20、24小时）评估了该真菌病原体的形态学（菌丝体外观、菌核分布）和表型（分生孢子的存在和大小、菌丝体生长速率、恢复情况）特征。结果表明，光照条件和光周期影响了该真菌病原体的形态学和表型特征。总体而言，在4小时和8小时光周期的黄色（590nm）LED灯下，抑制效果最佳。在455nm蓝色光下，8、16、20和24小时光周期均未形成分生孢子。因此，可以认为该真菌病原体的表型和形态特征取决于特定的光周期和LED光波长。这些结果有助于探索原创性研究方法，提出新的科学问题以供进一步研究，并提出新的绿色植物保护解决方案。
