根结线虫是许多农作物的重要病原,在农业生产中常极大地降低农作物的产量和质量。本研究中选用了7种不同染料,分别对侵入寄主根系组织初期的J2幼虫、雌虫产生的卵块团、雌虫尾部会阴花纹、及鉴别J2幼虫的死虫与活虫的染色方法进行了探索...根结线虫是许多农作物的重要病原,在农业生产中常极大地降低农作物的产量和质量。本研究中选用了7种不同染料,分别对侵入寄主根系组织初期的J2幼虫、雌虫产生的卵块团、雌虫尾部会阴花纹、及鉴别J2幼虫的死虫与活虫的染色方法进行了探索,这些方法便于有效了解和识别病原在侵染寄主不同阶段的形态。试验结果表明,溴酚蓝溶液对侵入根系的J2幼虫具有良好的染色效果;对于根系上的卵块团与雌虫的会阴花纹,cochenille red A或phloxine B溶液的染色效果较清晰;用甲基蓝与吖啶橙溶液分别对J2幼虫染色后,可相应地在可见光和荧光显微镜下判别J2幼虫中的死虫。展开更多

Pleurotus sapidus. Phellinus igriarius and 2 kinds of plants-Populus sp and Brassica chinensis. Of the four kinds of Est staining recipes tested.the recipe α-acetic acid-naphther showed the best effect.and followed by β-aceticacid-naphther, semicontent α-aceticacid-naphther and α+β-aceticacidnathpher.展开更多
