Bamboo plants are an essential element in Egyptian agriculture development. Nothing was found on propagation of Dendrocalamus giganteus under the Egyptian conditions. Thus, two trials were done to evaluate the effect of position of cuttings on the stem, time of propagation, indole-3-butyric acid (IBA) treatments, planting method on rooting of culm and culm-branch cuttings of bamboo. Three cutting types (basal, middle and tip) of single and double nodes were collected from culm (main stem) and culm-branch (lateral branch) cuttings of bamboo during September 2004 and March 2005. Culm-branch cuttings were treated for 24h with IBA at 0, 50, 100 and 200 ppm. Cuttings were planted horizontally and/or vertically in clay soil. The experiments were arranged in Randomized Complete Block Design as split plot with three replicates. The obtained data were statistically analyzed and revealed the following:
Culm-cuttings showed better rooting and growth parameters compared to culm-branch cuttings. In general, single-node cuttings of culm and culm-branch were better than the double nodes ones. Both branch types showed the highest rootability at March period of propagation. Meanwhile, September propagation was suitable to culm-branch cuttings only. Treated cuttings with IBA showed marked improvement in rootability. Basal cuttings contained more C/N ratio than that in tip ones. The best results were obtained from treating basal culm-branch cuttings with 100 ppm IBA. Vertical planting of double nodes cuttings reduced its rootability.
