An assumption can be postulated that the auxin produced in the stem apex may inhibit bud development by preventing differentiation of vascular connections between the cauline bundle and the bud primordia. This would deprive the primordia of nutrients and growth substances being translocated in the mainstream vascular elements. The assumption is that prior to decapitation, vascularization is incomplete to the laterals in johnsongrass and that after decapitation, vascularization becomes complete. Dr. C. A. Beasley has found that plants treated with ethrel will react the same as decapitated plants. This study was designed to examine ethrel treated plants and examine anatomically the vascularization of lateral bud procambial strands, to determine if ethrel will increase differentiation of vascular tissue, thus making the bud physiologically receptive to herbicides.
