ROOT GENERATION OF KARONDA (CARISSA CARANDAS L.) CUTTINGS IN RESPONSE OF SUCROSE AND IBA

This experiment was conducted at Bidhan Chandra Krishi Viswavidyalaya on vegetative propagation of Karonda by hardwood cuttings. The cuttings were treated with different concentrations of sucrose (2%, 4% and 6%) and IBA (7500 ppm, 8000 ppm and 8500 ppm) along with control and the experiment was replicated thrice. Treated cuttings were planted in polybags and kept in shade. The experimental results indicated that IBA 8000 ppm recorded highest rooting percentage (39.43%) followed by 4 per cent sucrose (37.12%) and lowest was recorded in control (23.13%). The maximum root length was observed in IBA 8000 ppm (6.85cm) followed by 4 per cent sucrose (6.49 cm) whereas control recorded only 4.15 cm root length.
