摘要
以繁殖系数Rf为指标,在盆栽条件下采用2龄幼虫接种法研究了7科20种植物与南方根结线虫(Meloidogyne incognita)的寄主关系。结果表明:绿架豆是易感寄主;油菜、翠绿青豆、棱形丝瓜、板蓝根、芥菜、四季精选小香葱、苏丹草和甜玉米是寄主;紫花苜蓿、八棱脆、黄芩、甜高粱、小麦、苇状羊茅、金谷2401、高羊茅是弱寄主,对M.incognita具有一定的抗性;蓖麻、高丹草、黑麦草是非寄主。
In pot trials,the reproduction of Meloidogyne incogintia in 20 plant species belonging to 7 families were evaluated via reproduction factor（Rf）.The results showed that Pachyrhizus vulgaris L.was an susceptible host;Brassica napus L,Giycine max（L）Merrill,Luffa cylindrica,Radix isatidis,Brassica napus L.,Allium schoenoprasum L.,Sorghum sudanense（Piper） Stapf.and Zea mays L.were good hosts;Medicago sativa L.,Cucumis melo L.,Scutellaria baicalensis Georgi.,Sorghum dochna（Forssk.）,Snowden,Triticum aestivum L.,Festuca arundinacea Schreb.,Setaria italica and Festuca arundinacea were poor hosts;Ricinus communis,Lolium perenne L.and Sorghum bicolor×S.bicolor var.Sudanense were assigned as nonhosts.The information of Rf value of different plant species could contribute to the integrated strategies for nematode management.
