Embodiment

[0184] Sample 1: POLYOX WSR N80 polymer in powder form (non-ionic water-soluble poly(ethylene oxide), obtained from The Dow Chemical Co., Midland, MI, has a specific solution viscosity at 5% as measured by a Brookfield viscometer 65-115cps) and ETHYLBLOC (a complex of 1-MCP and α-cyclodextrin in powder form, containing at least 0.14% by weight 1-MCP, obtained from FLORALIFE, Inc.) in a 3:1 weight ratio for dry co- Mix (dry blend). The resulting mixture was compression molded at 140°C to form a film from which 11 mm x 30 mm strips were cut to yield about 10 mg ETHYLBLOC / strip.

[0185] Sample 2: POLYOX WSR N80 polymer in powder form (nonionic water-soluble poly(ethylene oxide), obtained from The Dow Chemical Co., Midland, MI) was mixed with ETHYLBLOC (a powder obtained from FLORALIFE, Inc., 1 - Complexes of MCP and α-cyclodextrin, containing about 0.14% by weight of 1-MCP) were dry blended in a 9:1 weight ratio. The resulting powder was compression molded at 140°C to form a f...

Abstract

The present application discloses a composition comprising an ethylene blocker complex formed from an ethylene blocker product and a body and at least one water-soluble polymer, wherein the ethylene blocker complex and at least A water soluble polymer is blended.

Description

technical field [0001] Embodiments disclosed herein generally relate to delivery systems for ethylene blocking agents. More specifically, embodiments disclosed herein relate to compositions comprising an ethylene blocker complex and a water-soluble or water-swellable polymer. Background technique [0002] Ethylene is an important regulator of plant growth and development, which interacts with ethylene receptor proteins in plant tissues. In harvested fruits, vegetables and ornamentals, ethylene promotes color development, ripening, stimulates nut cracking, promotes flowering and reduces lodging in cereals. Ethylene is also produced by plants in biologically active amounts in response to various stresses, including drought, chilling, water-logging or flooding, hypoxia, and various pathogens. This stress-associated ethylene production is known to cause programmed cell death by binding to certain ethylene receptors in plants, resulting in premature plant or plant parts includi...
