The influence of controlled atmosphere and of rootstock on the quality of ‘Van’ sweet cherry
An investigation was conducted on the effect of several variables on the quality of ‘Van’ sweet cherries: storage regime (normal cold storage (NCS) and different kinds of controlled atmospheres (CA)-(CAt=2.5% O2; 10% CO2; CA2=2.5% O2; 15% CO2; CA3=2.5% CO2), 4 rootstocks (Prunus avium, Cab 11E, Maxma 14 and Giscla 5) and two harvest dates. Fruit samples were harvested on June 12 and 16, 2003. one sample per rootstock was harvested, and a sub-sample analyzed at the laboratory, while the other sub-samples were stored during 42 days, both in NCS and CA. At the end of the storage period, all preserved sub-samples were also analysed for fruit quality, using objective and subjective and subjective methodologies. Storage regime, rootstock and harvest date significantly influenced all the studied parameters of quality; fruit weight, firmness, titratable acidity, soluble solids content, skin (L*C*H*) and stem (Ls*as*) colour. Fruit size, titratable acidity, L* (Lightness), C* (chroma) were higher on fruits from invigorating rootstocks. Fruits from trees on Prunus avium had better aspect and fiavour after storage. Tasting panels considered fruits stored in controlled atmosphere, CA2 to have a better quality.
