Abstract

The emission of ethylene from climacteric fruit banana (Musa x paradisiaca L.) and non climacteric fruits lemon (Citrus limon Burm. F.) at different stages of ripening (from a few days after setting to full maturity stage) by the Laser Photoacoustic Spectroscopy System, developed in ENEA Frascati, was measured. A high ethylene production rate from mature banana fruit was found, as expected for climacteric fruit. Significant differences between ethylene emitted by the lemon after setting stage and by the young fruit were observed. Also ethylene emission from lemon fruits at different ripening stages (from light green to turning and full ripe) was detected. Depending on the ripening stage, differences in ethylene emission rates were found, although the emissions were low as expected for non-climacteric fruit.
