茄病镰刀菌(Fusarium solani f. sp. glycine)是一种土生细菌，通过侵染大豆根系引发猝死综合症。利用温室盆栽试验和须根培养试验研究了接种茄孢镰刀菌对13个不同基因型大豆的影响。结果表明：接种后所有盆栽大豆主根都有明显深褐色的侵染病斑；移植后21 d 测定了盆栽植株叶部发病程度，Peking 表现最为严重，然后依次为Spencer,Ripley,P3981,Williams...
镧素对镰刀菌Fusarium solani及其致病酶的影响
稀土 氧化镧(La2O3) 镰刀菌 毒力 致病酶活性
2016/3/31
采用琼脂平板生长速率法及液体培养基培养测定了La对镰刀菌Fusarium solani的抑制作用和毒力,并测定了其对病菌胞外的果胶酶、蛋白酶和纤维素酶等几种致病酶活性的影响。结果表明,随着La2O3浓度升高,对病菌菌丝生长的抑制作用增强,对病菌的EC50和EC95分别为278.2和552.0 mg/L;在一定浓度范围内,La提高了单位量菌丝所产生3种致病酶的活性,但由于菌丝生长受到抑制,除蛋白酶外...
