Název v původním jazyce

A comparison of apple cultivars regarding ethylene production and physico-chemical changes during cold storage

Popis výsledku v původním jazyce

Measurements of titratable acidity, soluble solids, firmness, ethylene production and weight 10ss were made for five apple cultivars held in cold storage for 100 days. Carbosieve G in the traps of the enrichment column, which has only a moderate affinityfor light hydrocarbons, was found to meet the requirements fur the optimal thermal desorption of ethylene (130°C for 2 minutes) from the enrichment column to the analytical column. ANOVA showed significant differences in all these five parameters between the five cultivars Golden Delicious Reinders, Resista, Topaz, Meteor and Rubinstep, and also in the course of storage. In all cases, the changes in titratable acids measured during storage were especially significant, but the observed changes in sugarlevels, as measured by refractometry, were too variable to be useful in this context. High rates of ethylene production impacted probably only indirectly on the los s of firmness and the other parameters which were measured. Discriminant
