THE INFLUENCE OF IBA, IAA AND NAA ON ROOTING OF CELOSIA ARGENTEA VAR.CRISTATA (L.) KUNTZE IN VITRO CULTURE
Journal Title: Folia Pomeranae Universitatis Technologiae Stetinensis Agricultura Alimentaria Piscaria et Zootechnica - Year 2016, Vol 37, Issue 325
Abstract
The formation of adventitious roots is an essential step in vegetative propagation. Well-developed root system allows for easier and faster adaptation of plants to ex vitro conditions. The aim of this study was to determine the effect of exogenous auxin on Celosia 46 M. Krupa-Małkiewicz and O. Mgłosiek argentea var.cristata (L.) Kuntze rooting under in vitro conditions and on ex vitro adaptation of those plants. MS rooting media were supplemented with IBA, IAA and NAA at subsequent concentrations 0.5, 1.0, 1.5, and 2.0 mg · dm−3. The results showed, that subsequent hormones had a positive effect on root development and morphology. The longest and thickest roots were formed in the presence of IBA at the concentration of 1.0 mg · dm−3. The highest percent of ex vitro survived plants was obtained after application of IBA and NAA (1.0 mg · dm−3). Plants survival ex vitro decreased (12.5–62.5%), when culture treated with IBA and NAA (1.5 and 2.0 mg · dm−3).<br/><br/>
