Some physiological effects of cycloheximide in soil on the tomato plant

Abstract

Cycloheximide applied as a drench to the soil of potted tomato plants caused reduced transpiration, and a marked reduction of exudate volume from the stumps of detopped plants. The exudate of treated plants showed increased levels of γ-aminobutyric acid and reduced levels of glutamine and α-ketoglutarate; Na ion concentration was increased and K ion concentration lowered. These effects were apparent within 2 h of application of cycloheximide.
