Abstract

ABSTRACT Due to the action of essential oils of thyme, lemongrass and rosemary against microorganisms and few studies on them in seed treatment, this study is proposed with vegetable seed. Therefore, the aim was to evaluate the effect of treatments with essential oils of thyme, lemongrass and rosemary on cauliflower seeds, inoculated with Aspergillus flavus. Three essential oils were used, at concentrations 0.0; 0.4; 0.8; 1.6 and 2.0%, arranged in a 3x5 factorial scheme, in a completely randomized design, with four replications. The essential oils of thyme (1.8%) and lemongrass (1.9%) had a fungistatic effect against A. flavus in cauliflower seeds. Thyme essential oil at 2.0% and lemongrass at 1.6% didn’t affect the physiological quality of seeds, being promising in the treatment of organic seeds. On the other hand, rosemary essential oil, despite not affecting germination and little affecting seed vigor, wasn’t efficient in controlling the pathogen.

百里香、柠檬草和迷迭香精油对花椰菜种子中黄曲霉的影响

摘要:由于百里香、柠檬草和迷迭香精油对微生物的抑制作用及在种子处理中的研究较少，本研究拟以蔬菜种子为研究对象。因此，目的是评价百里香精油、柠檬草精油和迷迭香精油对接种黄曲霉的花椰菜种子的影响。使用三种精油，浓度为0.0;0.4;0.8;1.6和2.0%，按3x5的阶乘方案排列，采用完全随机设计，重复4次。百里香精油(1.8%)和柠檬草精油(1.9%)对花椰菜种子中的黄曲霉有抑菌作用。2.0%百里香精油和1.6%柠檬草精油对有机种子的生理品质没有影响，在有机种子处理中具有广阔的应用前景。另一方面，迷迭香精油虽然不影响种子萌发，对种子活力影响不大，但对病原菌的防治效果不明显。
