Abstract
Byl stanoven obsah askorbové kyseliny v devíti kultivarech rajčat. U dvou z nich byla sledována stabilita askorbové kyseliny při skladování v chladničce. Zjištěné údaje byly srovnány s analogickým experimentem provedeným v Maďarsku. Naměřená časová závislost obsahu askorbové kyseliny úzce koreluje s publikovanými údaji o buněčném dýchání.
Abstract (in English)
The content of ascorbic acid in 9 cultivars of tomatoes was estimated. The time dependence of ascorbic acid content during storage in a fridge in 2 cultivares was measured, too. The data obtained were compared to a similar experiment made in Hungary. There is a good correlation between the time dependence of ascorbic acid content and published data about cell breathing.
