10 th <strong>Symposium</strong> on the Flora of Southeastern Serbia and Neighbouring regions,Vlasina 17 to 20 June 2010Effect of IBA on root formation in Beta vulgaris L.Tošić, S., Stojičić, D.,Mitrović, T.Department of Biology and Ecology, Faculty of Natural Science andMathematics, University of Niš, Serbiatosicsvetlana59@yahoo.comSugar beet is the major sucrose-producing crop grown in temperate zones.The aim of this study was to investigate the effect of different concentrations of IBAon root formation in few cultivars of Beta vulgaris L. After micropropagation,shoots of few cultivars of B. vulgaris L. were rooted on Gamborg media containing0.1, 0.5, 1.0 and 2.0 mg/l indole-3-butyric acid (IBA). The number of rootedplantlets and roots length were recorded at three DAIs (25, 25-44 and 44-45). Thetime of cultivation was also studied factor. Different concentrations of IBA hadsignificant effects on the examined parameters. The rooting ability increased withconcentrations of IBA. IBA at level 1.0 mg/l and 2.0 mg/l were found to be the besttreatment for rooting of micropropagated shoots. The percentage of rooted plantletsis higher for longer duration of treatment in culture. Key words: In vitro rootformation, Beta vulgaris L.
