Effect of growth regulators on sprouting and rooting behaviour in cuttings of Acacia catechu Willd. and Toona ciliata M. Roem

Author(s): Lalit Thakur, Tara Gupta and Rakesh Kumar
Abstract: Study shows the effect of growth regulators viz. different concentrations of IBA and NAA on sprouting and rooting behaviour in cuttings of Acacia catechu and Toona ciliata. Different concentrations 2000 ppm, 4000 ppm, 6000 ppm and 8000 ppm of both the auxins i.e. IBA and NAA were used as eight different treatments and a control was also set up. The cuttings were planted in polybags. In case of Toona ciliata maximum sprouting percent (52.22%) and rooting percent (36.61%) was recorded in cuttings treated with 8000 ppm IBA and in case of Acacia catechu, no rooting was observed. However, in Acacia catechu maximum sprouting percent (77.79%) with 11.29 cm sprouts was observed in cuttings treated with 2000 ppm of IBA. All the concentrations of IBA gave better results than the NAA concentrations in both the species
