Influence of indole butyric acid on root induction in daughter plants of strawberry

Abstract: Strawberry is a promising small fruit crop in Bangladesh. Farmers are giving priority to grow this short duration fruit in their field due to early fruiting and high market demand. The main obstacle is shortage of quality planting materials during planting time. Moreover, saplings produced from tissue culture techniques are very costly, as a result many of interested growers are unable to cultivate strawberry. Therefore, this study was undertaken to find out the impact of indole butyric acid (IBA) on root induction in strawberry daughter plants. Four concentrations of IBA (0, 100, 200 and 300 ppm) were applied at the base of newly born daughter plants of strawberry and inserted them in a polybag (10 cm×5 cm) with loamy soil for rooting. Thereafter, rooting performance of daughter plants was checked at 10, 15, 20 and 25 days after application (DAA) of IBA. The experiment was conducted following randomized complete block design with three replications. Results showed that different concentrations of IBA exhibited differently on root and shoot development of newly grown strawberry saplings. All the studied parameters were significantly influenced by IBA solutions except root length of saplings. Among the concentrations, 100 and 200 ppm IBA showed successful results in respect of all traits studied while 300 ppm IBA performed better in fresh weight of leaves of new saplings. However, it can be concluded that grower can use 100 and/or 200 ppm IBA solution at the base of newly grown daughter plants to expedite rooting and shoot development of strawberry saplings.
