Abstract

The diseases that attack the tomato crop are a limiting factor for its production and are difficult to control or eradicate. Stem and fruit rot and leaf blight caused by causes severe damage and substantial yield losses. Carbon nanotubes (CNTs) could be an alternative for the control of pathogens since they have strong antimicrobial activity, in addition to inducing the activation of the antioxidant defense system in plants. In the present study, multi-walled carbon nanotubes were evaluated on the incidence and severity of . Moreover, to the impact they have on the antioxidant defense system and the photosynthetic capacity of the tomato crop. The results show that the application of CNTs had multiple positive effects on tomato crop. CNTs decreased the incidence and severity of . Furthermore, CNTs increased the fruit yield of tomato crop and dry shoot biomass. The antioxidant system was improved, since the content of ascorbic acid, flavonoids, and the activity of the glutathione peroxidase enzyme were increased. The net photosynthesis and water use efficiency were also increased by the application of CNTs. CNTs can be an option to control in tomato crop, and diminish the negative impact of this pathogen.

摘要

侵袭番茄作物的病害是其产量的限制因素，且难以控制或根除。由[病原体名称未给出]引起的茎腐病、果腐病和叶枯病会造成严重损害和大幅减产。碳纳米管（CNTs）可能是控制病原体的一种替代方法，因为它们具有强大的抗菌活性，此外还能诱导植物中抗氧化防御系统的激活。在本研究中，对多壁碳纳米管在[病害名称未给出]的发病率和严重程度方面进行了评估。此外，还评估了它们对番茄作物抗氧化防御系统和光合能力的影响。结果表明，碳纳米管的应用对番茄作物有多种积极影响。碳纳米管降低了[病害名称未给出]的发病率和严重程度。此外，碳纳米管提高了番茄作物的果实产量和地上部干生物量。抗氧化系统得到改善，因为抗坏血酸、类黄酮的含量以及谷胱甘肽过氧化物酶的活性都有所增加。碳纳米管的应用还提高了净光合速率和水分利用效率。碳纳米管可以作为控制番茄作物中[病害名称未给出]的一种选择，并减少这种病原体的负面影响。
