摘要

由于营养价值高,豌豆作为豆科作物在世界各地种植。豌豆枯萎病是一种破坏性病害,在世界豌豆种植区造成严重损失。对主要豌豆产区的枯萎病发病情况进行了田间调查。在巴基斯坦Sahiwal地区观察到病原菌严重侵染和自然病害抑制的田地。收集样本是为了诊断疾病和抑制疾病的因素。土壤理化性状的测定结果显示,病害土壤与抑制土壤之间无显著差异。体外和盆栽的致病性试验表明,抑菌土具有天然的抑菌能力。此外,还设计了不同土壤处理下的离体和盆栽试验,探讨了抑制土壤中自然病害抑制的相关因素。结果表明,土壤抑制病害的机制是生物性的。从豌豆病根和健康根中分离得到的真菌菌株进行了毒力测定。结果表明,SAH09为从抑制土壤豌豆根中分离得到的非致病性尖孢镰刀菌。采用双重培养技术和盆栽试验,评价菌株SAH09对SAH03、SAH05和SAH10的分枝寄生行为。结果表明,非致病性尖孢镰刀菌SAH09分离株具有抑制所有致病性镰刀菌生长的潜力,并可能在抑制土壤中发挥自然病害抑制作用

Non-pathogenic Fusarium oxysporum contributes in the biological suppression of pea wilt in disease suppressive soil
Peas are growing all over the world as a leguminous crop due to high nutrients value. Fusarium wilt of peas is a destructive disease and causing deleterious loses in pea growing regions of the world. The fields were surveyed with disease incidence of Fusarium wilt in major pea growing areas. Fields with heavy pathogen infestation and natural disease suppressive were observed at District Sahiwal, Pakistan. The samples were collected to diagnose the disease and factors responsible in the suppression of disease. The results of soil physio-chemical properties showed no significant differences between diseased and suppressive soils. Pathogenicity assays both in-vitro and pot trial showed that suppressive soil has natural ability to suppress the disease. Furthermore, in-vitro and pot assays were designed with different soil treatments to investigate the factors responsible in the natural disease suppressiveness in suppressive soil. The results demonstrated that the mechanism involved in disease suppressive soil is biotic in nature. All isolated fungal strains from diseased and healthy roots of pea were subjected to biological assays to evaluate the virulence. The assays showed that isolate SAH09 is non-pathogenic Fusarium oxysporum which was isolated from the pea roots of suppressive soil. Isolate SAH09 was used in dual culturing technique and pot trial to evaluate the mycoparastism behavior against virulent pathogenic isolates SAH03, SAH05 and SAH10. Results concluded that isolate SAH09 of non-pathogenic Fusarium oxysporum has potential to suppress the growth of all isolates of pathogenic Fusarium and possibly play the role in natural disease suppression in suppressive soils
