The effects of the treated concentrationand time of 1- methylcyclopropene (1-MCP) on the postharvest D. Sonia orchid cut

Main Article Content

Abstract

1-methylcyclopropene (1-MCP) can inhibit the formation of endogenous ethylene and reduce its effects on cut flowers. The cuts of D. sonia orchid, treated with 1-MCP 0,2 µl/l, 6hrs, bore good results with the vase life up to 32 days, 12 days longer than that of the untreated, still stayed fresh with no abscission, etc.; abscission rate after 30 days storage was about 38% as compared to 85% of the untreated. The intensity of ethylene production and respiration rate in 1-MCP treatment were 3.25 nl/g.h and 5.20 mg CO2/g.h as compared to 4.5 nl/g.h and 7.75 mg CO2/g.h, respectively for the untreated; after 30 days of storage, anthocyanin and chlorophyll concentration were reduced to 33% and 32%, as compared to 52% and 42% for the untreated.
