Histochemical study of cabbage roots axenically parasitized by Pratylenchus penetrans revealed a five-fold increase in peroxidase activity (localized near lesions), pectic xylem plugs (resembling those caused by Fusarium), and accumulation of oxidase-mediated polyphenols in the region of mechanical injury. Fusarium-resistant cabbage was more susceptible to Pratylenchus than the Fusariunt-susceptible varieties, particularly in the formation of oxidized phenolic compounds. Of 13 fluorescent compounds detected by paper chromatography, one major spot was found to be ferulic acid and a minor one, catechin.
对被穿刺短体线虫无菌寄生的甘蓝根进行组织化学研究发现，过氧化物酶活性（定位于损伤部位附近）增加了五倍，出现了果胶木质部栓塞（类似于镰刀菌引起的栓塞），并且在机械损伤区域有氧化酶介导的多酚积累。抗镰刀菌的甘蓝品种比感镰刀菌品种对穿刺短体线虫更敏感，尤其是在氧化酚类化合物的形成方面。通过纸色谱法检测到的13种荧光化合物中，发现一个主要斑点是阿魏酸，一个次要斑点是儿茶素。
