In every development stage, plants produce ethylene, which can be beneficial and harmful. The ripening effect is by far the most economically crucial effect of the gas, followed by abscissing effects. Lesser known ethylene effects that need to be controlled in the supply chain are sprouting and pathogen detection. Ethylene is a phytohormone produced by…

On average, ethylene related issues cause at least 30% of flower waste. But what is it and why is it bad? Ethylene is the "silent killer" in floriculture. It is a gaseous plant hormone that is colorless, odorless and is present at undetectable levels in normal atmosphere unless you use sophisticated instruments to detect it.

Scope. This review presents an update of the current methods for ethylene monitoring in plants. It focuses on the three most-used methods – gas chromatography detection, electrochemical sensing and optical detection – and compares them in terms of sensitivity, selectivity, time response and price.

from plant to plant, they are typically: CH 4 + C 2H 6 < 0.15% C 2H 2 < 5 ppm CO 2 < 10 ppm The sample for these analyzers should be taken from the Ethylene Product line. The product specification for propylene (if applicable) is typi-cally: C 2H 6(MA) + C 3H 8(PD) < 2.0% Ethylene Product Specification Control To be able to successfully control ...

Ethylene is the "silent killer" in floriculture. It is a gaseous plant hormone that is colorless, odorless and is present at undetectable levels in normal atmosphere unless you use sophisticated instruments to detect it. As many hormones do, it takes fairly low concentration of this chemical to cause drastic effects on plants.
