Antagonism of Tryptamine Stimulated Growth in Apices of Avena Coleoptile by Xylamidine Tosylate

Abstract

XYLAMIDINE tosylate has been shown to antagonize peripheral actions of 5-hydroxytryptamine in isolated rat uterus and in a variety of in vivo tests with rats1. In studies of the role of tryptamine and other indole compounds in promoting the growth of excised Avena coleoptile apices I have found that xylamidine tosylate is a powerful antagonist of tryptamine stimulated growth in this plant tissue.
