Abstract:

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.

Key words: Amphicarpaea edgeworthii Benth., spore, Synchytrium decipiens
