Abstract
Greenhouse investigations were conducted to study the effect of girdling by the threecornered alfalfa hopper, Spissistilus festinus (Say), on translocation and nitrogen fixation in soybeans, Glycine max (L.) Merrill. Radiotracer studies with 14C glucose demonstrated that girdling of petioles effectively blocked the movement of assimilates in the phloem. Nodule number, nodule dry weight, root dry weight, leaf area, and nitrogen fixation activity were all significantly reduced by S. festinus feeding injury.This publication has 2 references indexed in Scilit:
