The development of sterile secondary tumours on hypocotyls of castor bean seedlings, inoculated with any of the ten isolates of Agrobacterium tumefaciens tested, were observed below the site of the primary tumours. Histopathological studies performed in the present work indicate that the observed secondary tumours were adventitious root primordia and not the ordinary type of secondary tumours. According to the available literature such findings are reported here for the first time. All the tested isolates of the present study were also able to initiate well defined roots in conjunction with crown gall (teratomas) on Bryophyllum crenata and Kalanchoe marmorata, but not in tomato.
在用所测试的10种根癌土壤杆菌分离株中的任何一种接种蓖麻籽幼苗的下胚轴后，在原发肿瘤部位下方观察到无菌性继发肿瘤的形成。本研究中进行的组织病理学研究表明，观察到的继发肿瘤是不定根原基，而非普通类型的继发肿瘤。据现有文献记载，此类发现首次在此报道。本研究中所有测试的分离株还能够在落地生根和花猫爪兰上与冠瘿（畸胎瘤）一起诱导出明确的根，但在番茄上则不能。
