Improving the Rooting Capacity of Stem Cuttings of Schefflera arboricola, Ficus benjamina and Syringa amurensis by Influenced different Concentrations of Indole-3-Butyric Acid (IBA)

摘要

The experiment was carried out to investigate the effect of different concentration of Indole-3-butyric acid (IBA) on the rooting ability of Scheffleraarboricola, Ficusbenjamina and Syringaamurensis . The treatments were factor A (IBA concentration) include four levels included: control (without IBA), 2000, 4000 and 6000 ppm IBA and factor B (three varieties) included: Scheffleraarboricola, Ficusbenjamina and Syringaamurensis. Treatment was evaluated in a factorial experiment at completely randomized design (CRD) with 3 replications. According to the obtained results, there was significant difference between IBA treatment and control on No. of roots per rooted cutting, Root length per rooted cutting, Root wet wt. per rooted cutting and Root dry wt. per rooted cutting. The best effect of different levels of IBA on the number of root (6.62 roots per plant) was obtained at 6000 ppm IBA. The highest of no. of roots per rooted cutting, root length per rooted cutting, root wet wt. per rooted cutting and root dry wt. per rooted cutting in the between of varieties was obtained in Ficusbenjamina . It can be concluded that using IBA affected rooting ability in all parameters in three plants.
