Research Abstract

Dracaena marginata, Lam. Cuttings (tip, middle and basal) were treated with certain growth regulators (IAA,IBA and NAA), each applied individually at 1000 ppm as a powder, beside control treatment to define the most effective combination of auxin and cutting types stimulating the rootability.The highest percentage of rooted cuttings was resulted from IBA (73%) fol-lowed by IAA (46%) and NAA (32%). Tip-shoot cuttings showed the maximum rooting percentage (46%), while basal cuttings resulted in the minimum rooting percentage, however, middle cuttings appeared intermediate responses. Also, IBA produced higher number and shorter roots th an IAA. Similarly, basal cut-tings produced the highest root number and formed the shortest roots. Generally, tip-shoot cuttings treated with IBA 1000 ppm proved to be more effective treatment enhancing the rooting percentage (88%) and improving root characteristics.
