Online published on 25 July, 2018. Abstract The present studies were done at the experimental farm of the Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, HP during 2008. The investigation was carried out on four standard commercial cultivars of chrysanthemum which were planted on different planting dates at an interval of 15 days starting from 9 April to 7 August. Significant differences were observed among the cultivars for all vegetative and floral parameters. Though successful flowering in standard type cultivars included in the studies was obtained in all the planting dates however later plantings resulted in cut stems of shorter length. Hence the optimum planting date for producing marketable cut stems was found to differ with the cultivar which was planted on 8 June in case of Purnima, 24 May in case of White Star and Tata Century and 23 July in case of Yellow Star among standard types. With the help of planting dates flowering could be regulated from 21 September to 25 November. Top Keywords Flower regulation, chrysanthemum, planting dates, flowering. Top |
