Abstract
Twenty-two essential oil samples from Germany and Albania were assayed to test their inhibitory and fungicidal activity against Cryphonectria parasitica (Murr.) Barr., the major causal agent of chestnut blight on chestnut trees, using the fumigant macrodilution method. Test concentrations of the oils in air phase were: 0.02, 0.04, 0.08, 0.16 and 0.32 ?l ml-1, and minimum inhibitory and fungicidal concentrations were determined. The strongest activity was shown by two samples of mint oil from Germany and Albania, and black pine at the concentration of 0.02 ?l ml-1 of air for both test isolates (M1 and 4S). The tested plant essential oils also included: eucalyptus, sage, silver fir and cade. Only three samples of EOs (mint (2) and black pine) were lethal to both isolates. Sage and silver fir oils were more toxic to the M1 isolate, while cade and eucalyptus oils were more toxic to the 4S isolate. Fifteen oils: mint (2), black pine, cade, eucalyptus, silver fir, sage, pine (4), oregano, lavender, and rosemary (2), inhibited the growth of Cryphonectria parasitica, and seven oils (two samples of mint, eucaliptus, black pine, sage, silver fir and cade) showed fungicidal effects on the pathogen.
对德国和阿尔巴尼亚的22份精油样品进行了抑菌和杀真菌活性研究。巴尔。板栗疫病的主要致病因子,采用大量稀释熏蒸法。油在气相中的测试浓度分别为:0.02、0.04、0.08、0.16和0.32 μ l ml-1,并确定了最低抑菌和杀真菌浓度。德国和阿尔巴尼亚的薄荷油样品和空气浓度为0.02 μ l ml-1的黑松样品(M1和4S)均表现出最强的活性。被测试的植物精油还包括:桉树、鼠尾草、银杉和凯德。只有3个EOs样品(薄荷(2)和黑松)对两个分离株都是致死的。鼠尾草和银杉精油对M1分离物的毒性更大,而桉叶和桉树精油对4S分离物的毒性更大。薄荷(2)、黑松、白桦、桉树、银杉、鼠尾草、松树(4)、牛至、薰衣草和迷迭香(2)等15种油类均能抑制该病原菌的生长,7种油类(薄荷、桉树、黑松、鼠尾草、银杉和白桦各2种)对该病原菌有杀真菌作用。
