Ethylene, ethanol, acetaldehyde and carbon dioxide released by Prunus avium shoot cultures

Abstract
Wild cherry (Prunus avium L.) shoots were cultured in closed vessels on a proliferation medium and the volatile substances released during incubation at photosynthetic photon flux density of 30 μmol m–2 S–1 were determined. Ethylene and CO2 started forming at the beginning of the incubation period and a linear relationship between their formation was observed even at high CO2 concentrations. After 30 days of culture, CO2 reached a concentration of 30%. Shoots released elhanol and acetaldehyde after several days of incubation.
