Abstract
CO2 laser photothermal deflection (limit 1 nl l(-1)) and photoacoustic detection (limit 6 pl l(-1)) systems were used to measure ethylene em ission rates from point sources of a wide range of mature nonclimacter ic and climacteric fruits. In addition, an infrared gas analyzer was u sed to measure CO? from the same samples. As well as total rates, the percentages emanating from the skin, tissue at the distal end (floral scar) and the pedicel were established. Possible links with fruit beha viour during abscission are discussed.
