Abstract: The present invention relates to a composition comprising a cyclopropene, for example 1-MCP, encapsulated in a cyclodextrin matrix, a hygroscopic compound, yeast and/or other enzymes involved in the production of alcohols and aldehydes from organic substrates, and, optionally an organic substrate for the enzymes. The composition of the present invention provides, under controlled conditions, the co-release of the cyclopropene, alcohols, aldehydes and carbon dioxide, which work together to improve the quality of plants during storage. Methods and commercial packages employing these compositions are also disclosed.

Abstract: An apparatus and method for determining the photosynthetic activity of a plant by determining the chlorophyll fluorescence of the plant is provided. The apparatus includes a light impermeable housing, a light to illuminate the housing, a light intensity in the housing and to adjust the light intensity controller. The light intensity may be between zero and 700 micromoles of photons per square meter per second. The monitor may be a photodiode protected by light filters which permit only light of wavelengths corresponding to plant fluorescence emission to pass to the photodiode. A computer analysis of the data obtained, corrects for Dark and Straylight signals in the housing and normalizes the data by correcting for the Fo fluorescence. A method of estimating Fo is provided which includes illuminating a light impermeable chamber housing a plant with light of a pre-determined intensity, measuring the fluorescence emission, determining the slope of a first regression line prior to full opening of the shutter; determining the slope of a second regression line of measurements after the shutter is fully opened and determining the intersecting point between these two lines. A method of determining the corrected and normalized fluorescence emissions from a plant is provided.
