广西根结线虫病害的病原鉴定

THE IDENTIFICATION OF ROOT-KNOT NEMATODE POPULATIONS IN GUANGXI

从广西不同地区采集的28种植物根结线虫病的病原,按病原线虫的主要形态学特征和寄主反应的鉴定方法,对每种病原进行了分类鉴定。其中穗状鸡冠花、胡椒、蕹菜、胡萝卜,芭蕉芋、鸡蛋果、莞荽(香菜)、苋苯、荷包豆、吉庆果、黄麻、黄穗鸡冠等根结线虫病的病原都是属南方根结线虫1号小种;风仙花、辣椒、蕹菜、番茄、独头鸡冠花、红穗鸡冠、罗汉果、黄麻、芹菜根结线虫有一种是南方根结线虫1号小种,另一种是爪哇根结线虫;甜叶菊、姜根结线虫病的病原有一种是南方根结线虫1号小种,另一种是花生根结线虫1号小种;吉庆果、四季海棠、茄、棕竹、柳树的根结线虫病的病原是爪哇根结线虫;罗汉果、丝瓜、红麻根结线虫病的病原有一种是爪哇根结线虫,另一种是花生根结线虫1号小种;花生根结线虫病的病原是花生根结线虫1号小种。发现二个新种:即水稻根结线虫病的病原是林氏根结线虫;柑桔根结线虫病的病原是孔氏根结线虫。

Twenty-eight populations of root-knot nematode from host plants were collected from different places in Guangxi.According to the main morphological characteristics of the species of genus Meloidogyme and the reactions On hosts, each population was identified. The pathogen of Celosia cristata, Pipper nigrum, I pomoea aquatica, Daucus carota var. sativa, Canna edulis, Passiflora edulis, Coriandrum sativum, Amaranthus tricolor, Phasealus multiflorus, Solahum pseudocapsicum, Corchorus capsularis and Celosia sp., is Meloidogyne incognita race 1; one of the pathogens of Impatiens, balsamina, Capsicum frutescens, I pomoea aquatica, Lycopersieun esculentum, Celosia crstata, Celosia sp., Momordica grosvenori, Corchorus capsularis, and Apium graveolens is Meloidogyne incognita race 1,and another is Meloidogyne javanica;the pathogens of Steria rebaucliana, Zingiber officinale are both Meloidogyne incognita race 1 and Meloidogyne arenaria race 1; the pathogen of Solanum pseudo-capsicum, Begonia semperflorens,Solanum melongena,Rhapis humilis and Salix babylonica is Meloidogyne jaoanica; the pathogen of Momordica grosvenori, Luffa cylindrica and Hibiscus cannabinus are both Meloidogyne jaoanica and Meloidogyne arenaria race 1; the pathogen of Arachis hypogaea is Meloidogyne arenaria race 1; the nematodes from Oryza sativa and Citrus sp. were not reported before, and in this paper, they were named Meloidogyne lint and M.kongi, respectively.
