    摘要:

    为明确深圳市威胁蔬菜生产的根结线虫种类和种群分布,对其主要蔬菜基地的根结线虫进行调查,并采用传统形态学与分子生物学结合的方法进行种类鉴定。结果表明: 在深圳市13个蔬菜基地的121个调查采样点中,有11个蔬菜基地的74个采样点发现根结线虫Meloidogyne spp., 蔬菜根结线虫发生率为61.16%; 从采集的样本中纯化得到76个根结线虫种群,并鉴定出4种根结线虫,其中69个种群为南方根结线虫M.incognita, 3个种群为爪哇根结线虫M.javanica, 1个种群为花生根结线虫M.arenaria, 3个种群为象耳豆根结线虫M.enterolobii; 同时发现2个采样点有南方根结线虫和象耳豆根结线虫的复合种群。

    Abstract:

    In this study,a survey was carried out to identify Meloidogyne species from rhizosphere of vegetables in Shenzhen City by means of morphology, isozymes and molecular analysis. The results showed that among 121 samples of roots and rhizosphere soil from 13 different vegetable bases in Shenzhen City, Meloidogyne were found in 74 samples from 11 different fields, and the incidence rate of Meloidogyne was 61.16%. Seventy six populations of Meloidogyne were purified, and 4 species were detected and identified, including 69 populations of M.incognita, 3 populations of M.javanica, 1 population of M.arenaria and 3 populations of M.enterolobii. At the same time, mixed populations of M.incognita and M.enterolobii existed in 2 samples. In conclusion, Meloidogyne distribute widely in vegetable fields in Shenzhen City,and M.incognita is the dominated species.
