Abstract

Seedlings of Capsicum frutescens L. and Zinnia elegans L. were treated with 1 and 100 ppm 2.4-dichlorophenoxyacetic acid (2.4-D), 100 and 10,000 ppm (2-Chloroethyl) phosphonic acid (ethephon), and 10 and 1000 ppm methyl ester of 2-chlorofluorenol-9-carbonic acid [morphactin (chlorofluorenol)]. Low concentrations of the materials applied singly had minor effects while morphactin and 2.4-D in combination modified morphological development in various ways. Ethephon did not seem to cause interactive effects when applied with 2.4-D and (or) morphactin. High concentrations of each material applied singly modified plant morphology of pepper and zinnia and inhibited growth of zinnia.
