Abstract: 1-Methylcyclopropene (1-MCP) is a synthetic plant
growth regulator used commercially to delay ripening of fruits.
1-MCP (SmartFreshTM) is applied in gaseous form (as a fumigant)
in the cool store room. This paper uses a porous medium
computational fluid dynamics model to numerically analyze
the distribution of 1-MCP in cool store rooms for apple fruit.
The effects of air circulation, room shape, and bin material
were investigated. Dose calculation based on filling density
was explored. The 1-MCP distribution in commercial cool
stores, under room cooling condition,was uniform irrespective
of room shape. Rooms filled with fruit in wooden bins deplete
25 % more of the active substance than rooms filled with fruit
in plastic bins. The calculated dose increases linearly with the
amount of fruit in the cool store (filling density). Hence,
this study suggests that dose prescription based on filling
density is feasible.
