Abstract

Examples were given of the oncolithic influence of the polyploidizing agents acenaphtene and podophyllin, on "phytocarcinomata", induced in tomato and castor oil plants by Bacterium tumefaciens. Another polyploidogenic agent, vitamin K, failed to elicit tumour reduction in Pelargonium zonale. Polyploid shoots were observed in tomato plants as a result of the combined actions of acenaphtene and the bacterial infection, while neither acenaphtene alone, nor the inoculations alone gave rise to similar structures. Species and race-specific responses were observed in the different plants to the administered chemicals, in view of which attention was drawn to the importance of endogenous factors in the reactions observed.
