三籽两型豆上迷惑集壶菌的初步观察

迷惑集壶菌（Synchytrium decipiens）是三籽两型豆上的一种专性内寄生菌，侵染三籽两型豆的豆荚和假根，形成不规则瘤状凸起，瘤状体内着生许多病原菌的营养体，阻碍导管中水分和无机营养物质的运输，最终导致三籽两型豆的枯死。本文首次报道三籽两型豆豆荚和假根上的迷惑集壶菌，并进行了初步观察和研究，为三籽两型豆的资源开发和人工种植中病害形态学鉴定以及病害防治提供研究基础。

Preliminary observation on Synchytrium decipiens in Amphicarpaea edgeworthii Benth.

Synchytrium decipiens, an obligate parasite in Amphicarpa eaedgeworthii Benth., infects legume and rhizoid of Amphicarpaea edgeworthii Benth.Irregular nodular intumescentia will then shape. Large amount of trophosomes of pathogenic bacteria in tumor body will hinder the transport of water and inorganic nutrients, and eventually cause exsciccation of Amphicarpaea edgeworthii Benth.We originally report Synchytrium decipiens in the legume and rhizoid of Amphicarpaea edgeworthii Benth.We also make preliminary observation and investigation. This provides a reference for resource development of Amphicarpaea edgeworthii Benth,identification of plant disease morphology and prevention and cure of insect pest in artificial cultivation.
