title: Ethylene Contamination of CO(2) Cylinders: Effects on Plant Growth in CO(2) Enrichment Studies.
abstract: Ethylene concentrations of CO(2) cylinders from different sources ranged from <0.1 up to 475 microliters per liter. The effect of the higher ethylene concentrations on growth of species in CO(2) enrichment studies was examined. Though maize plants showed no effect on C(2)H(4), 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.
