摘要: 摘 要:[目的]了解海南肾茶根结线虫的种类、特征及其对肾茶生长的影响。[方法]从感染线虫的肾茶根系中分离线虫的雌虫、雄虫和幼虫,用显微镜观察描述线虫特征并对照线虫特征图样进行鉴别。通过致病性实验研究线虫对肾茶生长的影响,并通过肾茶的长势、叶绿素、蛋白质含量等指标来评价。[结果]实验分离得到了海南肾茶的根结线虫,并成功进行了致病性实验。[结论]实验所用海南肾茶感染的线虫为南方根结线虫(Meloidyne incognita.)。线虫严重影响肾茶的生长发育,使肾茶植株长势不良甚至死亡,重要代谢物质如蛋白质、叶绿素a含量明显下降。

Abstract: Abstract: [Objective] Understand the type and characteristic of the Root-Knot Nematode in the clerodendranthus spicatus.(Thunb.)C.Y.Wu and the influence which grows to the clerodendranthus spicatus.[Method] Separates the Root-Knot Nematode’s female and male and larva from root system which the clerodendranthus spicatus. were infected with the Root-Knot Nematode, view and describe the Root-Knot Nematode’s characteristic under a microscope and discern the type through compares the Root-Knot Nematode’s characteristic pattern. Study the influence of growth which the clerodendranthus spicatus. were infected through the pathogenic experiment, and make an objective appraisa through viewing the clerodendranthus spicatus.’s growing trend and setting-out content of the chlorophyll and protein.[Result] Separated and get the clerodendranthus spicatus. (Thunb.)C.Y.Wu.’s Root-Knot Nematode, and has succeeded in doing the pathogenic experiment .[Conclusion] The Root-Knot Nematode in the clerodendranthus spicatus.(Thunb.)C.Y.Wu is the Meloidyne incognita. .It is serious interfere with the clerodendranthus spicatus.’s growth. The clerodendranthus spicatus. is doing bad even died, the important metabolism material like protein and chlorophyll’s content is obvious drops.
