Effect of a Brief CO(2) Exposure on Ethylene Production.

abstract：:Numerous studies have demonstrated a rapid increase in the respiration rate during aging of slices of tuber and storage roots. To determine the molecular mechanisms of this phenomenon, the role of enzyme binding to the subcellular particulate fraction has been assessed in carrot (Daucus carota L.) and sugar beet (Beta...
