摘要:
对带菌土壤、病残体进行传病试验,研究了人工接种条件下种子带菌条件及带菌种子传病情况,结果表明,带菌土壤和病残体无论是在当年还是越冬后都可有效地传播大豆疫霉根腐病,是大豆疫霉根腐病的主要初侵染源和传播途径。人工接种可以导致大豆种子带菌,但只有在病菌直接接触到豆荚才有这种结果。幼荚期接种豆荚可以使荚内的豆粒严重发病,豆粒被一层菌丝包裹,这些豆粒虽然本身不能萌发,但能作为接种体导致邻近的健康植株发病。作者通过大量的播种试验,到目前为止还末能证实来自自然发病田的种子常规越冬后能够传病,相关工作正在进行中。
Abstract:
Sudies o n the trannsmission of Phy tophthora ro ot ro t of soybea n had beencarried o ut w ith the soil debris and th e seeds w hich came f rom natura l diseased fields asw ell as the soil and seeds which inoculated w ith the pathog en. It show s thatPhytophthora ro ot ro t o f soy bean is mainly t ransmi tted by the soi l a nd dcbri s w hichnaturally infected wi th pathog en, The seeds ca n be infected w hen the young seed pod isinoculated wi th pa thogen. When pla nted, these seeds can cause nearby plant s to beinfected altho ugh they ca n no t germinate themselv es. So far w e have no suf ficientevidence to testi fy the seeds naturally infected w ith the pa thog en in g rowing field cant ransmi t this disease.
