Abstract
AN experimental study of two primary symptom reactions of tomato and other plants to invasion by the vascular parasite Bacterium solanacearum —namely, petiole-epinasty and adventitious root production—has been made. It has been found that in the tomato epinasty is confined to the lower petioles irrespective of whether the inoculation is made at the top or the bottom of the stem. Growth and bending occur generally in the basal part of the petiole. No epinasty of individual leaflets such as occurs in the case of treatment with ethylene gas has been observed.
