How can ethylene released by a houseplant be measure?

Question

Which instruments or meters can do this? I'd like to measure plant stress. Thanks.

Answer 1

scientists would use an instrument called a gas chromatograph. One can also use bioassays: dark-grown pea seedlings grow very differently in high ethylene (their stems become short and fat, and they do not grow vertically but horizontally: this is called the triple response).
