Plant senescence is the process of aging in plants. Plants have both stress-induced and age-related developmental aging. Chlorophyll degradation during leaf senescence reveals the carotenoids, and is the cause of autumn leaf color in deciduous trees. Leaf senescence has the important function of recycling nutrients, mostly nitrogen, to growing and storage organs of the plant. Unlike animals, plants continually form new organs and older organs undergo a highly regulated senescence program to maximize nutrient export.

Use of lysophosphatidylethanolamine (18:1) and lysophosphatidylinositol to retard senescence and to enhance fruit ripening
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.
