摘要: 本研究通过温室栽培,以‘兰箭3号’春箭筈豌豆(Vicia sativa ‘Lanjian No.3’)为试验材料,探究了4个磷水平(P0=0,P1=10 mg·kg-1,P2=20 mg·kg-1,P3=30 mg·kg-1)下丛枝菌根(Arbuscular mycorrhiza,AM)真菌摩西斗管囊霉(Funneliformis mosseae)对箭筈豌豆炭疽病的影响。结果表明,供P水平可影响AM真菌侵染率以及炭疽病发病率,P3水平下AM真菌侵染率最高, P1处理发病率和病情指数最高。AM真菌显著降低炭疽病发生。植物防御酶超氧化物歧化酶(Superoxide dismutase, SOD)及过氧化物酶(Peroxidase, POD)活性在P处理下均有所降低;炭疽病和供P水平对AM真菌的侵染具有交互效应,在低P(P0,P1)水平表现为促进,在高P(P2,P3)水平则表现为抑制。本研究通过研究AM真菌与P协同作用对箭筈豌豆响应炭疽病的影响,为箭筈豌豆生产中磷肥合理施用及利用AM真菌防控炭疽病提供了理论依据。

Abstract: In this study, we investigated the effects of arbuscular mycorrhizal(AM)fungus on Vicia sativa ‘Lanjian No.3’ growth and disease resistance under four phosphorus levels(P0=0, P1=10 mg·kg-1, P2=20 mg·kg-1, P3=30 mg·kg-1)in the greenhouse. The results showed that P level affected the infection rate of AM fungi and the incidence of V. sativa anthracnose, and the AM fungal infection rate was the highest at P3 level. AM fungus was able to inhibit disease caused by anthracnose. The activity of plant defense enzyme superoxide dismutase (Superoxide dismutase, SOD) and peroxidase (Peroxidase, POD) decreased at P treatments; Disease and P supply had an interactive effect on fungal colonization of AM, promoted at lower P (P0, P1) levels and inhibited at higher P (P2, P3) levels. In conclusion, this study demonstrated the synergistic effect of AM fungi and P in response to anthracnose, which provided a theoretical basis for using P and AM fungi to manage anthracnose in common vetch production.
