Vegetative propagation of Acacia catechu, Dalbergia sissoo and Prosopis cineraria by cuttings.
Mature hardwood and softwood cuttings from 1-yr-old branches of 20-yr-old trees of Acacia catechu, Dalbergia sissoo and Prosopis cineraria were tested for their rooting capacity. For P. cineraria, coppice shoots were also tested. Cuttings were treated with different concentrations of auxins (IBA and NAA) in a mist chamber. D. sissoo rooted easily, with 100% success rate for both hardwood and softwood cuttings, irrespective of auxin treatment. A. catechu and P. cineraria were difficult to root, but did root under treatment; the greatest success rates were 50% (softwood cuttings of A. catechu with 100 mg/litre IBA) and 25% (coppice shoots of P. cineraria with 1000 mg/litre IBA), respectively. Auxins did not induce rooting in mature hardwood cuttings of A. catechu or P. cineraria.
