摘要: 花生果腐病是由茄腐镰刀菌和尖孢镰刀菌等病原菌引起的土传病害,目前尚无有效防治该病害的登记药剂及措施,给花生产业造成了巨大经济损失。为了筛选防治花生果腐病的绿色高效杀菌剂,本研究以茄腐镰刀菌和尖孢镰刀菌为靶标菌,采用菌丝生长速率法从26种植物精油中筛选出百里香和肉桂两种高抑菌活性精油,通过GC-MS分析了两种精油的主要化学成分,继而通过菌丝生长速率法和孢子萌发法测定了百里香和肉桂精油及其高效抑菌化合物百里香酚和肉桂醛对两种镰刀菌菌丝生长和孢子萌发的抑制活性,并通过离体接种测定其保护和治疗防效。结果表明,百里香酚和肉桂醛分别为百里香和肉桂精油的高效抑菌化合物。百里香精油、肉桂精油、百里香酚和肉桂醛抑制茄腐镰刀菌菌丝生长的EC50值分别为444.44、295.66、74.35、286.09 mg/L,100 mg/L浓度下对茄腐镰刀菌孢子萌发的抑制率分别为63.33%、75.33%、94.67%和47.33%。各测试物质的治疗防效大于保护防效,且500 mg/L浓度下百里香酚(97.67%)、肉桂醛(94.57%)、肉桂精油(96.30%)防效显著高于百里香精油(45.18%)。由此可见,百里香酚、肉桂醛和肉桂精油具有用作植物源杀菌剂防治花生果腐病的潜力。

Abstract: Peanut pod rot is a soil-borne disease mainly caused by Fusarium solani and F. oxysporum. Currently, there was no effective registered fungicides and methods to control peanut pod rot, thereby causing serious economic losses on peanut industry. This study screened the antifungal activity of 26 essential oils against F. solani and F. oxysporum using the mycelial growth inhibition method and found that Thymus mongolicus and Cinnamomum cassia essential oils showed highest inhibitory activity. Then, we analyzed the chemical components of T. mongolicus and C. cassia essential oils using GC-MS and determined the inhibitory effects of two essential oils and their major components thymol and cinnamaldehyde against the mycelial growth and spore germination of two Fusarium pathogens using the mycelial growth inhibition method and spore germination method. Finaly, the protective and curative efficacy of these test essential oils and compounds were determined on detached peanuts by artificial inoculation. Results indicated that thymol and cinnamaldehyde was the highly antifungal compound of T. mongolicus and C. cassia essential oil, respectively. The EC50 value of T. mongolicus essential oil, C. cassia essential oil, thymol and cinnamaldehyde against F. solani was 444.44, 295.66, 74.35 and 286.09 mg/L, respectively; and their inhibition at 100 mg/L on the spore germination of F. solani was 63.33%, 75.33%, 94.67% and 47.33%, respectively. The curative efficacy of each test substance was higher than its protective efficacy. At 500 mg/L, the efficacy of thymol (97.67%), cinnamaldehyde (94.57%), C. cassia essential oil (96.30%) was significantly higher than that of T. mongolicus essential oil (45.18%). Above results showed that thymol, cinnamaldehyde, C. cassia essential oil had great potential to be used as botanical fungicides to control peanut pod rot.
