Numerous pesticides, including fungicides, are applied every year to crop plants. However, such application may affect the plant metabolism and thus crop quality. Strawberry is an economically important crop, but the fruits are highly susceptible, especially to fungal diseases. In the present study, the effects of two fungicides, Cuprozin progress and SWITCH, on the metabolism of two cultivars and the wild strawberry were tested, focusing on primary (amino acids, (in)organic acids, sugars, total phenolics) and specialized metabolites (aroma volatiles), which determine the fruit flavor. The fungicide treatment significantly affected 11 out of 57 metabolites, while 20 of those differed between strawberry types and 27 were affected by the interaction of both factors. Given these modifications in metabolites in response to the treatments, the taste and quality of the strawberries may pronouncedly change when plants are treated with fungicides.
每年都会有大量的农药，包括杀菌剂，应用于农作物。然而，这种应用可能会影响植物的新陈代谢，从而影响作物的质量。草莓是一种经济上重要的作物，但果实非常容易受到影响，特别是受到真菌病的影响。在本研究中，测试了两种杀菌剂 Cuprozin progress 和 SWITCH 对两种品种和野生草莓代谢的影响，重点关注决定果实风味的初级（氨基酸、（无机）酸、糖、总酚）和特殊代谢物（香气挥发物）。杀菌剂处理显著影响了 57 种代谢物中的 11 种，而其中 20 种在草莓类型之间存在差异，27 种受到这两个因素相互作用的影响。考虑到这些代谢物对处理的反应，当植物用杀菌剂处理时，草莓的味道和质量可能会明显改变。
