Was researched influence of exogenous ethylene on apricots of variety "Velkopavlovická". The fruits were harvested at the maturity stage of the primary content of chlorophyll in their skin. At the plant material was determined by the concentration of titratable acids, fruit penetrometer firmness and soluble solids content. Additionally, a loss of weight. The fruits were treated with exogenous ethylene for 24 hours in a sealed vessel at 200 ppm concentration. Concentration verified by gas chromatography (GC / MS). Were stored for 14 - days at 3 ° C and 20 ° C. For each group of fruit was also a control group (untreated exogenous ethylene). Laboratory tests performed on days 0, 7 and 14 days after treatment. For fruit treated with ethylene decrease the strength of fruits and color changes - loss of chlorophyll. On the other properties of fruits have more influence than ethylene storage temperature. Sensory evaluation was carried out of all categories of fruits according to the parameters taste, firmness, color. Top evaluated fruits were treated exogenous ethylene stored at a temperature of 20 ° C and worst fruits were evaluated control (untreated) stored in the temperature of 3 ° C.
