AB  - Cryopreservation represents a suitable method for long term storage of different plant genetic
resources. The aim of this study was to develop protocol for cryopreservation of Viola cornuta
shoot tips using one step freezing method with chemical dehydration of tissue with modified
Plant Vitrification Solutions (PVS2 or PVS3). Shoot tips (1-2 mm) of two-week cold acclimated
shoots were cultured on ½MS medium with 0.3 M sucrose for one day before treatment with loading solution (2 M glycerol, 0.4 M sucrose) for 30 min. Osmotic dehydration with PVS2 solution (30% glycerol, 15% ethylene glycol and 15% DMSO in liquid ½MS medium with 0.4 M sucrose) were tested at 0 °C or 24 °C. Osmotic dehydration with PVS3 (50% sucrose, 50% glycerol in liquid ½MS medium) were tested at 24 °C for 45 min. After the treatment the explants were directly immersed in liquid nitrogen (LN) for at least one day. Re-warming was performed at 42 °C in water bath for 2 min. After re-warming, the PVS solutions were replaced with unloading solution containing 1.2 M sucrose for 20 min. Re-warmed shoot tips were cultured on ½MS medium with 0.1 mg L-1 BAP. We observed that PVS2 solution is cytotoxic for V. cornuta shoot tips and cannot be used for cryopreservation. However, cryopreservation with PVS3 solution was successful, where 71.9-100% shoot tips survived treatment before immersion to LN and 31-40% survived after re-warming from LN. Regrowth of cryopreserved shoot tips with new well-formed leaves was obtained after four weeks of culture.

AB  - Impatiens hawkeri (Balsaminaceae) je ukrasna biljna vrsta poreklom sa Nove Gvineje. Krioprezervacija predstavlja metod za dugotrajno čuvanje biljnog materijala na -196C u tečnom azotu koji se koristi i za eliminaciju patogena kod biljaka.1 Vrste roda Impatiens su izrazito osetljive na tretmane dehidratacije koji prethode zamrzavanju.2 Takođe, koncentracija saharoze u hranljivim podlogama utiče na morfogenetski potencijal tokom gajenja u kulturi in vitro.3 U ovom radu smo ispitivali uticaj prekulture vrhova izdanaka na povišenoj koncentraciji saharoze (6%), kao i vitamina C na preživljavanje i regeneraciju biljaka posle hemijske dehidratacije vrhova izdanaka sa rastvorima za vitrifikaciju (PVS2 i PVS3). Vrhovi izdanaka I. hawkeri su izrazito osetljivi na tretman sa 100% PVS2 rastvorom. Najveći morfogenetski potencijal posle izlaganja PVS2 rastvoru su pokazali vrhovi tretirani sa 50% PVS2 rastvorom kada je dolazilo samo do kalusiranja vrhova izdanaka. Potpuna regeneracija biljaka posle PVS2 tretmana postignuta je uz dodatak vitamina C u hranljivoj podlozi u koncentraciji od 100 mg/l. Najbolji rezultati preživljavanja i regeneracije biljaka posle odmrzavanja postignuti su korišćenjem metode vitrifikacije sa 100% PVS3 rastvorom u trajanju od 45 min. Izdanci gajeni na hranljivoj podlozi sa 6% saharoze su pokazali veće preživljavanje (49,4%) posle izlaganja ultra niskim temperaturama u odnosu na izdanke gajene na podlogama sa 3% saharoze (26,5 %).
