Parmar University of Horticulture and Forestry, Nauni, Solan, (H.P.) during 2020-21. The experiment was laid out in a completely randomized design factorial with three replications. Experiment consisted of three propagules; shoot tip cuttings, stem cuttings and leaf bud cuttings of two cultivars ‘Surf’ and ‘Purnima’ with thirteen different growth regulator treatments for quality planting material during different months i.e. April, May and June. Among the different propagules, shoot tips was found to be better than stem cuttings and leaf bud cuttings but leaf bud cuttings increased the rate of regeneration of plants by 10 times as compared to shoot tips. Among the two cultivars ‘Purnima’ was found to be better than ‘Surf’ and the best growth regulator treatment was NAA 500ppm followed by NAA 250ppm irrespective of BA foliar spray. Propagation under trenches was found superior over propagation under mist chamber and June planting had highest percent rooting than April and May plantings under trench and mist chamber. These techniques will open up a new vista for multiplication of chrysanthemum plants which will cater to the problems related to the non- availability of quality planting material and also beneficial for off-season cultivation.EnglishThesis
