以玉米穗粒腐病的优势病原菌串珠镰刀菌Fusarium moniliforme为接种菌源,采用4种接种方法进行比较,以针刺果穗较深处(籽粒与穗轴间)发病最重,花丝喷雾法发病最轻;接种时期以玉米乳熟期接种为好;接种浓度10×40倍下每视野60个分生孢子;接种量以每果穗接种2.5ml孢子悬浮液发病最重。同时规范了病情分级标准及品种抗、感程度划分标准。采用规范程序,对63份玉米自交系及杂交种进行了抗病性鉴定。
Fusarium moniliforme, the dominant pathogen of corn ear rot, was used as the inoculation source. Four methods of inoculation were used to compare the results of the four inoculation methods. Light; Inoculation period to corn milky period inoculation as well; Inoculation concentration of 10 × 40 times per field of 60 conidia; Inoculation amount per spike inoculated 2.5ml spore suspension the most severe. At the same time regulate the grading standards and varieties of anti-sense of degree of division of standards. 63 maize inbred lines and hybrids were tested for disease resistance using a standardized procedure.
