中文摘要: |
为了了解陕西省内的根结线虫生防资源,筛选更好的根结线虫生防菌,在陕西省9个县市采集了118份感染根结线虫的蔬菜植株根部样品,采用直接分离法从根结线虫卵、卵囊及雌成虫体上共分离到199株拮抗真菌。除43株不产孢及疑难种未鉴定外,其余分属于镰刀菌属、拟头孢霉属、芽枝霉属、拟青霉属、链格孢属、掘氏梅里霉属、单顶孢属、青霉属等22个属。其中镰刀菌属、拟头孢霉属及芽枝霉属真菌出现频率较高,约占总分离数的53%,且不同地区间拮抗真菌的种类与数量也存在较大差异。 |
英文摘要: |
To investigate the bio control resources and obtain better effective antagonistic fungi to control root knot nematode, 118 vegatable root samples infected by root knot nematodes were collected from 9 counties of Shaanxi Province. 199 antagonistic fungal isolates were isolated respectively from eggs, egg masses and females of root knot nematodes. These antagonistic fungi were identified to 22 genera, including Fusarium, Cephalosporiopsis, Paecilomyces, Cladosporium, Alternaria, Drechmeria, Monacrosporium, Penicillium etc and 43 sterile fungi. The isolation frequency of Fusarium spp., Cephalosporiopsis spp. and Cladosporium spp. took up 53%, and the species and the amount of antagonistic fungi of different samples were distinctly different in the regions. |
