Optimization of IBA dose for rooting in fig (Ficus carica L.) cuttings

Abstract

Present investigation was carried out to optimize the dose of rooting hormone, Indole-3-butyric acid (IBA) for rooting of fig cv. Brown Turkey cuttings under arid irrigated zone of Punjab. The hard wood cuttings were collected during January and treated with different concentrations of IBA (0, 100 ppm, 1000 ppm, 2000 ppm, 3000 ppm). The results of investigation indicated that the treatment of IBA @ 1000 ppm induced maximum cutting success (68.6%), number of buds sprouted per cutting (2.4), number of leaves (11.3), shoot length (37 cm), fresh weight of shoots (36 g) and dry weight of shoots (11.7 g). Also, the maximum number of roots per cutting (69.5), fresh weight of roots (4.9 g) and dry weight of roots (2.4 g) was recorded under the same treatment after 180 days of planting. It is concluded that treatment of cuttings with IBA @ 1000 ppm for five minutes was helpful in rapid vegetative propagation of fig crop in the arid part of the Punjab state.
