Response of indole butyric acid (IBA) on sprouting and shoot growth of stem cuttings of star gooseberry (Phyllanthus acidus)

The experiment was conducted to find out the response of IBA on sprouting and shoot growth of stem cuttings of star gooseberry (Phyllanthes acidus Skeels) during 2013–14, in polyhouse conditions at Regional Horticultural Research Station, Navsari Agricultural University, Navsari. A experiment was laid out in completely randomized design with factorial concept (FRBD) having 14 treatment combinations, comprising with two factors: (1) types of cutting (hardwood cutting and top cutting) and (2) different concentration of IBA (0, 500, 1000, 1500, 2000, 2500 and 3000 mg/litre) and repeated trice. Among different types of cutting and IBA concentration, hardwood cutting and 2000 mg/litre were individually as well as in their combination most beneficial for early sprouting and maximum sprouting percentage. Similar trend was observed on the growth parameters of shoot like number of shoots, length of longest shoot, fresh and dry biomass of shoot and survival percentage.
