Povzetek


V raziskavi je je bila ovrednotena obstojnost gomoljev belega jama (Dioscorea rotundata Poir.) med shranjevanjem v lesenih zabojih in na platojih. Kriteriji za ovrednotenje ohranjenosti gomoljev so bili izguba mase, kalitev in gnitje gomoljev v obdobju 20 tednov, od marca do junija 2015. Meritve temperature in relativne zračne vlage v prostorih hrambe so potekale trikrat dnevno v obdobju trajanja poskusa. Meritve izgube mase vsakega gomolja so potekale tedensko, pravtako odstranjevanje kalečih poganjkov. Povprečna temperatura zraka in relativna vlažnost v poskusnih zabojih sta bili 29.7 °C in 78.6 %, v platojij 30.7 °C in 76.5 %. Gnitja gomoljev ni bilo pri nobenem načinu hrambe. Gomolji belega jama, shranjeni v zabojih, so kumulativno izgubili 9 % mase, tisti v platojih pa 15.0 %. Shramba v zabojih se je izkazala boljša glede izgube mase in hranilne vrednosti gomoljev.
