Influence of gas mixtures on fruit softening and volatile formation in two plum cultivars (Prunus domestica L.)

Popis výsledku v původním jazyce

The 36 volatile compounds detected by SPME (solid phase microextraction) in the plum cultivars 'Stanley' and 'Vajlevka' included 1 hydrocarbon, 11 alcohols, 9 aldehydes, 1 ketone, 10 esters and 4 terpenoids. Both cultivars were stored at 1.0 to 1.5 °C and kept in three diffirent experimental atmospheres. One had fluctuating anaerobiosis (FAN), with oxygen concentrations around the limits of aerobic metabolism, with 0.5 to 0.6 % O2 and 0.2 to 0.3 % CO2. There were two controlled atmospheres (CA), the first (CA1) with 0.9 to 1.0 % 02 and 9.0 to 9.2 % CO2 and the second (CA2) with 1.5 to 2.0 % 02 and 14.6 to 15.0 % C02 plus a regular atmosphere (RA) with 20.9 % 02 and 0.1 % C02 as a control. Both cultivars showed a maintenance ofskinfirmness in all threetreatments in comparison to a regular atmosphere. Statistical analysis confirmed that the biogenesis of volatiles was very slow at the onset of ripening and developed progressively towards the end ofstorage in the gas mixtures. Among the
