Effect of Different Concentrations of IBA and Time of Taking Cutting on Rooting, Growth and Survival of <i>Ficus binnendijkii</i> ‘Amstel Queen’ Cuttings

In this research, in order to study the effect of different concentrations of IBA and time of taking cutting on rooting, growth and survival of F. binnendijkii ‘Amstel Queen’ cuttings, a test was conducted in a randomized complete block design with four replications. Treatments were consisted of four levels of hormones: 0 (control), 2000, 4000 and 6000 mg/l, with two intervals of time for taking cuttings (late June and early September). Results showed that highest root percentage, root number and fresh weight of root were for IBA concentrations of 4000 and 6000 mg/l and cuttings taken early in September. The maximum of mean length of root and longest root were achieved in concentration of 6000 mg/l IBA, taking cutting in early September. The highest survival percentage of plants was recorded in concentrations of 4000 and 6000 mg/l IBA, early September being the appropriate time of taking the cutting. The greatest length of new shoots was obtained in concentration of 4000 mg/l IBA, cutting in late June, while the maximum number of new leaf was in IBA concentration of 2000 and 4000 mg/l, with cuttings taken also in late June.
