Abstract
The present investigation was conducted under polyhouse during January, 2005 to October, 2005 at the Garden Section of Department of Horticulture, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. The present study was undertaken to comprehend and evaluate the effect of different budding seasons, rooting hormone (IBA) and cultivars on vegetative as well as flowering attributes of rose (Rosa sp.). Cuttings of Rosa indica var. Odorata treated with different concentrations of IBA (200, 500, 1000 and 1500 ppm) and budded separately with buds of cvs. Super Star, Kiss of Fire and Happiness were planted in four periods at 15 day interval between January to March. Findings of the investigation revealed that both vegetative as well as flowering attributes were recorded excellent when budding was done in second fortnight of January for all the three cultivars. Cuttings treated with IBA at 1000 ppm and budded with buds of cv. Happiness (V3) recorded maximum number of roots (45.0). Maximum bud take percentage was recorded with cv. Super Star (83.4). Maximum plant height was attributed to cv. Super Star (V1) at 240 days after planting (72.2 cm). Days to flower bud appearance was recorded minimum for cv. Happiness (38.0 days). Cultivar Happiness exhibited maximum bud length (2.85 cm) and bud diameter (0.94 cm) in case of cuttings planted during the second fortnight of January, whereas longest stalk length of the flower was attributed to cv. Kiss of Fire(50.3cm). During the investigation period the three factors IBA, cultivar and time of budding interacted significantly with each other.
