abstract
Present investigation was carried out to determine the successful vegetative propagation of Aquilaria malaccensis to study the effect of best potting media, time of planting material collection, effect of different hormonal concentration and type of cuttings for bud sprouting and rooting. In potting media selection where, best budding (25.75±0.83) recorded in 500ppm IBA followed by (18.25±0.83) in 500 ppm NAA from hard cuttings in coarse sand. Cuttings in potting media coarse sand treated with different hormones viz. IBA, IAA and NAA solution in six different combinations showed distinct variations in bud sprouting and rooting of the cuttings. Cuttings collected from Titabar area of Jorhat district were showed best results in bud sprouting from hard cuttings (7.75±0.83) of 500 ppm NAA followed by (3.75±0.43) in 500 ppm IBA. The potential of propagation of the species through hard cuttings showed best rooting (40%) 200 ppm IBA and (33%) in 200ppm NAA respectively. Highest number of rooting and survivality was recorded in the hard branch cuttings collected from Titabar area of Jorhat district under nursery condition. However, the highest survival percentage (75-80%) was observed in the rooted cuttings transplanted in soil: sand: FYM with IBA and NAA respectively.
