Abstract

Surface sterilization is the most important step in preparation of explants for micropropagation, because controlling fungal and bacterial contamination of woody plant from field sources is very difficult. Six sterilizing agents: sodium hypochlorite (NaOCl), calcium hypochlorite [Ca(ClO)2], sodium dichloroisocyanurate (DICA), mercuric (II) chloride (HgCl2), silver nitrate (AgNO3) and hydrogen peroxide (H2O2) were tested for sterilization of ?Oblacinska? sour cherry buds, by varying their concentration and time of exposure. The aim of this study was to establish best surface sterilization for in vitro propagation of ?Oblacinska? sour cherry. Aseptic cultures of ?Oblacinska? sour cherry were established from axillary buds which were placed in nutrient medium, supplemented with plants hormones 6-benzylaminopurine (BA), 1- naphthaleneacetic acid (NAA) and gibberellic acid (GA3). The results indicated that among these sterilizing agents silver nitrate (AgNO3) at concentration of 1% for 20 minutes was the best for controlling the infection, whereas sterilization with sodium dichloroisocyanurate (DICA) at concentration of 1% for 10 minutes was not satisfactory.Cilj ovog istrazivanja bio je da se utvrdi najbolji postupak povrsinske sterilizacije pupoljaka za in vitro propagaciju Oblacinske visnje. Povrsinska sterilizacija je najvazniji korak u pripremi eksplantata za mikropropagaciju, buduci da je za uspostavljanje asepticne kulture kod drvenastih kultura iz polja jako tesko kontrolisati gljivicnu i bakterijsku kontaminaciju. Sest sredstava za sterilizaciju: natrijum hipohlorit (NaOCl), kalcijum hipohlorit [Ca(ClO)2], natrijum dihlorizocijanurat (DICA), ziva (II) hlorid (HgCl2), srebro nitrat (AgNO3) i vodonik peroksid (H2O2) testirani su za povrsinsku sterilizaciju pupoljaka Oblacinske visnje u razlicitim koncentracijama i razlicitom vremenu tretiranja. Asepticna kultura je uspostavljena izolacijom meristema iz aksilarnih pupoljaka koji su smesteni na hranjivu podlogu sa biljnim hormonima: benziladenin (BA), naftil sircetna kiselina (NAA) i giberelinska kiselina (GA3). Rezultati su pokazali da je od svih sredstava za sterilizaciju AgNO3 u koncentraciji od 1% i trajanju sterilizacije 20 minuta pokazao najbolje rezultate u sprecavanju infekcije, dok sterilizacija sa DICA u koncentraciji od 1% i trajanju od 10 minuta nije bila zadovoljavajuca.
