摘要/Abstract

摘要： 本文报道对杨梅根结线虫病的研究及病原鉴定结果。该病症状为:病树根部形成大小不一的根结,内有乳白色囊状雌虫及棕色卵囊;后期根结腐烂,病树叶片黄化脱落,梢枯乃至死亡。病原鉴定确认,引起该病的根结线虫有3个种:爪哇根结线虫(Meloidogyne javanica)、南方根结线虫(M.incognita)和北方根结线虫(M. hapla)。爪哇根结线虫为优势种。

Abstract: Root-knot nematode of bayberry (Myrica rubra) is a new disease which has developed in Fujian province since 1987. The symptoms of the disease were noticed initially as non-uniform root-knot at root systems in the affected trees and subsequently many milky white female root-knot nematodes and brown egg capsules in the root-knots. Finally the root-knots rotted, and dropping of etiolated leaves and the die back of the branches occurred. The identification of pathogen confirmed that this infection disease was caused by Meloidogyne spp., i. e. M. javanica, M. incognita and M. hapla. The first one was the predominant species among them.
