Dendrocalamus Bamboo is of special interest to me, as it is one of the bamboo species which is almost fully solid. It offers to be a good substitute for wood, which is a raw material for us, in the handicraft industry.
The few plants, that we have here, were established using seed from ICFRE.
The culms of this particular genotype are fully solid till about 18 feet. Subsequently, the inter-nodal cavity begins to appear. The diameter of the cavity however, continues to be small till the next 10 to 15 feet. Above 25 feet, the diameter of the cavity (hole) begins to increase. The wall thickness, overall, is very good. The bamboo has been seen to grow to about 35 to 40 feet. The outer diameter at breast height is about 4 to 6 inches.
I have been trying, in vain, to develop a vegetative nursery to establish a plantation! . I have tried using auxins ( NAA and IBA) at various strengths ( 1000 to 5000 ppm) but failed to root the cuttings. I wonder, if any specialist on the Agro-Forestry or Bamboo forum could offer guidance and help.
