Abstract
Pri in vitro uzgoju biljaka koristimo hranjive podloge. Hranjive podloge sadrže sve potrebne hranjive elemente potrebne biljci za rast i razvoj. Kako bi biljkama omogućile rast i razvoj u sterilnim uvjetima hranjive podloge moraju se sterilizirati. Najčešće se steriliziraju u autoklavima, no u novije vrijeme moguća je i sterilizacija u mikrovalnoj pećnici koja je jeftinija i dostupnija od autoklava. U istraživanju je korištena mikrovalna pećnica. Istraživanje je obavljeno na dva načina: 1. Prvo istraživanje obavljeno je u trajanju od 5 minuta po tretmanu pri intenzitetu zračenja od 100 W, 180 W, 300 W, 450 W i 600 W. Korišteno je 23 Erlenmayerove tikvice sa 50 mL hranjive podloge. 2. Drugo istraživanje obavljeno je u trajanju od 5 minuta po tretmanu pri intenzitetu zračenja od 180 W, 300 W, 450 W i 600 W. Korišteno je 20 Erlenmayerovih tikvica sa 50 mL hranjive podloge i staklena laboratorijska čaša sa 400 mL hladne destilirane vode. Tijekom istraživanja bilježeno je ključanje hranjive podloge koje je dalo najbolje rezultate za sterilnost pri najvećem intenzitetu zračenja od 600 W. Isto tako kod isparavanja najveći postotak isparavanja imali su tretmani na 600 W, a najmanji na 100 W i 180 W. Prema rezultatima dobivenim u istraživanju može se zaključiti da je potreban veći intenzitet zračenja kako bi došlo do sterilnosti i ključanja hranjive podloge.
Abstract (english)
When growing plants in in vitro conditions, we use nutrient media. Nutrient media contain all the nutrients needed by the plant for growth and development. To allow plants to grow and develop under sterile conditions, the nutrient medium must be sterilized. They are mostly sterilized in autoclaves, but more recently, sterilization in a microwaves is also possible, which is cheaper and more affordable than autoclaves. In this study microwave was used. The search was done in two ways: 1. The first study was performed for 5 minutes per treatment at a radiation intensity of 100 W, 180 W, 300 W, 450 W and 600 W. 23 Erlenmayer flasks were used with 50 mL of nutrient medium. 2. A second study was performed for 5 minutes per treatment at radiation intensity of 180 W, 300 W, 450 W and 600 W. 20 Erlenmayer flasks were used with 50 mL of nutrient medium and a laboratory glass with 400 mL of cold distilled water. During the study, boiling of the nutrient medium was reported, which gave the best results for sterility at the highest radiation intensity of 600 W. During evaporation, treatments at 600 W had the highest percente of evaporation and the treatments at 100 W and 180 W had the lowest percentages. Based on the results of this study it was concluded that a higher intensity of radiation is required for sterility and boiling of the nutrient medium to occur.
