Abstract
An experiment was carried out at the Department of Horticulture at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh for the investigation of the performance of different concentration of Indole-3-Butyric Acid (IBA) for sprouting and rooting potential of Bougainvillea spectabilis stem cutting during the period from May 2013 to August 2013. Five treatments viz. T0: Control; T1: IBA in dust form; T2: IBA 500-ppm; T3: IBA 1000-ppm and T4: IBA 2000-ppm were exploited on the experiment with five replication. In case of T2, T3 and T4 cuttings were soaked for 24 hours on the respective solutions. From the experiment it was found that IBA play an important role for successful asexual propagation of bougainvillea through cutting. Better performance was found when cut stems were soaked for 24 hours before the establishment of stem cutting. But performance was inhibited by increasing concentrations of IBA in terms of all of the features on which data had taken. During the experimental period, data was taken on different attributes and T3 (1000-ppm) was performed as the best among the treatments which as followings: days to first rooting (4.0), days to first sprout bud initiation (5.3), number of sprout bud/cutting (3.6), number of leaves/cutting (35.2), length of sprout (15.0 cm), number of branches/cutting (4.7), number of root/cutting (64.2), number of sub root/cutting (25.8), longest root length (33.2 cm), longest root diameter (0.51 mm), rooting % (100%), survival % of rooted cuttings (100%). Though 100% rooting was also found in 500-ppm and 2000-pmm but only 1000-ppm was resulted 100% survival of rooted cuttings.
