ETHYLENE‐STIMULATED GROWTH AND AUXIN ANSPORT IN <i>RANUNCULUS SCELERATUS</i> PETIOLES

Abstract

Summary Ranunculus sceleratus petioles elongate rapidly when submerged or treated with ethylene. The concentration of ethylene in submerged plants is approximately 7 nl ml ‐ , sufficient to account for the submerged response. Ethylene (50 nl ml ‐1 ) enhances IAA transport through petiole sections within 1 hour of treatment.
