Clonal propagation techniques in ailanthus triphysa (dennst.) alston

Ailanthus triphysa is the most preferred species in the safety matches industry. Under the tree improvement programme, selections of this species are to be multiplied by vegetative means for large scale deployment in clonal plantations for productivity enhancement and to meet the industrial demand. Vegetative propagation by rooting of juvenile coppice shoots of A. triphysa was assessed by subjecting them into different concentrations of Indole Butyric acid (IBA). Juvenile shoots were collected from the stumps of the selected trees. IBA with different concentrations (250 ppm, 500 ppm, 750 ppm, 1000 ppm, 1500 ppm, 200 ppm, 2500 ppm, 3000 ppm, 3500 ppm, 4000 ppm and control) were tried to initiate rooting. 2000 ppm concentration was performing maximum level of rooting. This treatment may be used for mass multiplication of A.triphysa.
