  • Use of lysophosphatidylethanolamine (18.1) and lysophosphatidylinositol to retard senescence and to enhance fruit ripening
    Patent number: 6426105
    Abstract: The present invention relates to a method of enhancing fruit ripening and stability and of delaying senescence in fruit and other plant tissues. This method consists of applying an effective amount of a lysophospholipid, such as lysophosphatidylethanolamine (18:1) (hereinafter referred to as “LPE (18:1)”) or lysophosphatidylinositol (hereinafter referred to as “LPI”) to the fruit and other plant tissues. Lysophospholipids such as LPE (18:1) and LPI were found to be superior to other lysophospholipids in delaying senescence and in inhibiting phospholipase D, a key enzyme in mediating membrane deterioration during of plant senescence. LPE (18:1) and LPI are naturally occurring and environmentally safe. Their use could replace many environmentally toxic compounds that are currently being used to retard senescence of flowers, fruits and leaves and to enhance fruit ripening.
