Abstract

This research aimed to study effects of wounding, IBA, NAA and their combinations on rooting ability and shoot sprouting in White Adriatic fig cuttings. Cuttings were collected and treated with (in ppm w/w): 0, wounding, 2000 IBA, 4000 IBA, 500 NAA, 1000 NAA, wounding+2000 IBA, wounding+4000 IBA , wounding+ 500 NAA, wounding+ 1000 NAA, 2000 IBA+500 NAA, 4000 IBA+1000 NAA, wounding+2000 IBA+500 NAA, wounding+4000 IBA+1000 NAA. To record the timing and percentage of rooting, cuttings were treated with wounding, (in ppm w/w) IBA and NAA or without wounding and auxin as control. Total carbohydrates, total and reducing sugar, total indols, total free amino acids, total and conjugated phenols, N, P, K in leaves were determined. The results revealed that, treating cuttings with IBA /or NAA raised the rooting percentages. In addition data mentioned that wounding treatment and quick dipping of cuttings in IBA and NAA gave the highest percentages of rooting and consequently the high survival percentages in comparison to other treatments. Results also showed that the growth parameters of stem, roots and other chemical constituents took the same trend as affected by the previously treatment. The best treatment for rooting and shoot sprouting were (in ppm) wounding plus the highest rate of growth regulators (4000ppm indole butyric acid and 1000ppm of naphthalene acetic acid, either alone or together) 4000 IBA+1000 NAA, since it produced higher root length, better root morphology and higher shoot sprouting.
