Ethylene Contamination of CO2 Cylinders

Abstract

Ethylene concentrations of CO₂ cylinders from different sources ranged from 2 enrichment studies was examined. Though maize plants showed no effect on C₂H₄, growth of tomato, rice, mung bean, and phalaris was substantially reduced by ambient concentrations of ethylene in the range of 0.02 to 0.06 microliters per liter.
