Abstract
The invention is a method and composition for preserving plant material, and an apparatus and assay for determining one or more anti-biofilm agents useful for preserving or extending the shelf life of plant material.
Description
Composition and Method for Preserving Plant Mat~ariat 1. f=ield of the fnvendon (G441] This invention relates to preserving plants, more specifically to preserving and or extending the Life of plants such as cut flowers.
11. Background of the invention
11. Background of the invention
(0002] A need still exists for extending or improving the life of a flower after it has been cut or harvested. A need also exists for determining one or more anti-biofitm agents and one or more ethylene inhibitors that are useful in preserving or extending the life of a cut flower.
Ifl. Summary of the invention [t~Rt7~] The inventors believe that one or more biafiims are present in the stem of a cut flower, and their presence in the interstitial portions of the stem prevents the effective use of agents that might pmlong the life and quality of the cut flower.
(0004] This invention prravicies an apparatus and method for determining one or more anti-biofitm agents that are effeGcive against one or more biofilms in plant material.
(0005] The invention also comprises contacting the plant material with a composition comprising one or more anti-biof fm agents, thereby extending storage life or preserving the plant material, such as a cut flower. The invention also comprises contacting the plant rnate~~al with a composition comprising one or more ethylene inhibitors, thereby extending storage life or preserving the plant material or flower.
~l?OQ6~ tn accordance with the pre$ent invention, it has been determined that tt~e presence of one or more biofilms andlor ethylene in plant material may affect the longevity ar life of the plant or cut Rawer. The present invention provides a method and t~wa~sss ooc:,~1 apparatus for assaying the presence of those laiofiim$ andlor ethylene, a method and apparatus far screening a panel of anti-biofiJm agents andlor ethylene, and a method and composition for preserving plant material by contacting the plant material with an anti-biofilm agent andlor an ethylene inhibitor.
iV. petailed Descripti~ri of the Invention [00'73 The invention comprises a methfld for determining an anti-biofilm agent effective against one ar more biofitms in plant material. The invention also comprises a method for determining an ethylene inhibitor effective against ethylene in plant material.
j0008~ ~lrt emk~odiment of the invention includes preserving the Iife or quality of plant material by contacting it with a composition comprising one or more anti.-biofiim agents.
The anti-biofiJm agent is itself a preservative agent to eliminate or reduce the presence of a biofiJm in the plant material.
jQ009~ An embodiment of the invention includes assaying plant material for the presence of a biofilm or ethylene andtor determining one or more anti-biofiJm agents or ethylene inhibitor effective against the biofilm or ethylene, respectively.
j0010~ An embodiment of the invention includes extending or preserving plant material by contacting a plant material, such as a cut flower, with a composition comprising an anti-biofilm agent, an ethylene inhibitor, or combinations thereof.
