The present investigation “Effect of various concentrations of growth hormone (IBA) and types of cutting sections on rooting and growth of Platanus orientalis L. branch cuttings” was carried out at experimental field of Division of Forest Biology and Tree Improvement, Faculty of Forestry, Benhama during the years 2018 and 2019 to standardize optimum concentration of growth hormones and to determine the best section of branches for rooting and growth of Platanus orientalis L Cuttings of 8 inches length were prepared from different sections (apical, middle and basal) of branches collected from Platanus orientalis L. trees in January. Before planting in March, the cuttings were treated with varying concentrations of IBA in a quick dip method for 60 seconds. The experiment was laid in Completely Randomised Design (Factorial). In all, there were thirty-nine treatment combinations comprising of twelve concentrations of IBA (1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000, 10000, 11000 and 12000ppm) and Control with three cutting sections (apical, middle and basal). In case of IBA concentrations, cuttings of Platanus orientalis L. treated with IBA@6000ppm yielded best results for all the growth parameters viz., rooting (41.33%), root length (26.48 cm), average number of roots per plant (8.56), sprouting (98.89%), shoot length (35.84 cm), collar diameter (6.45 mm), number of branches per plant (2.67), leaf area (44.67 cm2), fresh and dry biomass of shoot (21.57 g) and (10.97 g) respectively, fresh and dry biomass of root (15.49 g) and (5.11 g) respectively and in case of cutting sections, basal cuttings proved to be superior as they recorded highest results for all the characters like rooting , root length, average number of roots per plant, shoot length, collar diameter, number of branches per plant, fresh and dry biomass of shoot, fresh and dry biomass of root
Platanus orientalis L, IBA, Root, Biomass, Branches
The current study is the first of its kind in which effect of different concentrations of growth hormone and types of cutting sections on rooting ability of Platanus orientalis L. branch cuttings has been conducted. The best concentration of auxin for vegetative propagation of Platanus orientalis L. is IBA@6000ppm since it greatly improved all growth parameters recorded as compared to control. IBA@6000ppm was most effective for rooting of Platanus orientalis L. cuttings. The best section of cutting for vegetative propagation of Platanus orientalis L.is basal as it performed better in all characters recorded than apical and middle section of cuttings. In order to gain maximum rooting, a combination of IBA@6000ppm and basal cuttings should be used
