Abstract: The present investigation was carried out at experimental farm of Division of Floriculture, Medicinal and Aromatic Plants, SKUAST-K, Shalimar. The experiment comprised of four experiments. The first experiment was conducted to study the effect of different concentrations of IBA (0, 4000, 6000 and 8000 ppm) on rooting in semi-hardwood cuttings of Taxus baccata L. It was observed that IBA treatment of 6000 ppm recorded minimum number of days taken to root emergence (62.84 day) in comparison to control (93.07 day). The treatment also recorded the highest root number (17.20), longest primary roots (7.60 cm) and maximum rooting percentage (77.50%). The 2nd experiment was performed to study the rooting in terminal cuttings of Crataegus laevigata L. as influenced by etiolation and IBA treatments (0, 1000, 2000 and 3000 ppm). With 3000 ppm IBA treatment and control, only callusing was observed. Rooting was noticed for 2000 ppm and 1000 ppm treatments. 2000 ppm IBA treatment and etiolation proved to be the best treatment combination recording the maximum rooting percentage (53.28), maximum number of primary roots (5.43) and longest primary roots (6.58 cm). The aim of the third experiment was to study the effect of time of planting and different concentration of IBA (0, 2000, 3000 and 4000 ppm) on rooting in Myrtus communis L. cuttings. IBA treatment of 4000 ppm and August planting proved to be the best treatment combination recording the maximum rooting percentage (88.80). In the fourth experiment on Punica granatum var. Flore pleno it was observed that IBA 600 ppm is the ideal treatment recording the lowest number of days taken to root emergence (71.44) and maximum rooting percentage (82.50). An overview of the investigation reveals that all the IBA treatments significantly differed from control.
