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 under greenhouse
conditions. 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 culmbranch
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 of IBA showed markedly improvement
its 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.
