Effect of sucrose and auxins on rooting of karonda cuttings, Carissa carandas L

The experiment was conducted at Agricultural Research Institute, Rajendranagar, Hyderabad on vegetative propagation of karonda by cuttings. Karonda cuttings were treated with different concentrations of sucrose and auxins viz 2 and 4 per cent sucrose; 7000, 8000 and 9000 ppm IBA and 1000, 2000 and 3000 ppm NAA along with control (water dip) and the experiment was replicated thrice. Treated cuttings were planted in polybags, kept in shade and analyzed for various rooting parameters. The results indicated that IBA 8000 ppm recorded highest number of roots (10.89) which was at par with IBA 9000 ppm (10.44) followed by 4 per cent sucrose (9.99) and lowest was recorded in control (3.77). The maximum length of longest root per cutting was observed in case of IBA 8000 ppm (6.56 cm) which was at par with 9000 ppm IBA (6.35), 4 per cent sucrose (6.31 cm) and IBA 7000 ppm (6.12 cm) whereas control recorded only 2.57 cm root length. IBA 8000 ppm recorded highest rooting percentage (34.44%) and lowest (13.33 %) was observed in control.
