Disclosed are compositions that comprise one or more N-acylethanolamine compounds for maintaining the freshness and appearance of
cut flowers, floral products, decorative foliage, fruits, and other
plant cuttings. More specifically, the present invention provides methods for treating and storing
cut flowers, Christmas trees, fruits, and other severed
plant parts that preserve the appearance, freshness, fragrance and / or aesthetic qualities of the botanical products. Using the disclosed compositions, the
shelf life of
cut flowers was substantially prolonged, in many cases 2 to 5 times longer than untreated flowers, with the treated flowers or foliage appearing healthy and viable, and without
wilting,
dehydration, leaf drop, or visible signs of
senescence. Likewise, treatment of ornamental coniferous plants with the anti-senescent compositions delayed deterioration and leaf drop, while extending the overall appearance and quality of the plants and
plant cuttings.
