Effect of Ethylene on Carnation Keeping Life
Carnations are susceptible to flower damage when exposed to relatively low ethylene levels (2,3). Sources of ethylene that may cause injury include automobile exhaust, fruits, flowers, diseased or injured tissues, burning or decaying organic matter, growth regulators, and improperly vented or adjusted greenhouse heaters (1). Ethylene damage can result from long exposures to low ethylene concentrations or short exposures to high concentrations.
