Abstract:

The present investigation was carried out at Research Farm, Division of Floriculture and Landscape Architecture, SKUAST-Kashmir, Shalimar, Srinagar, J&K (India) during the year 2010 to evaluate the effect of two growth regulators IBA and NAA @ 500, 1000, 1500 ppm in comparison to control (without any growth regulator treatment) and growing medium combinations (sand 100%, sand 85% + manure 15%, sand 70% + manure 30%, sand 70% + manure 15% + soil 15%, sand 85% + soil 15%) on the rooting of three rootstocks of rose (Rosa indica, Rosa banksiae and Rosa bourboniana). Main effect of growth regulators and genotype was significant on majority of rooting characteristics. IBA (1000 ppm) recorded minimum days to root initiation (23.33), maximum rooting (72.22%), root length (6.42 cm) and field survival (82.38%). Among the genotype, Rosa indica performed better, recording maximum rooting (75.24%), primary root number (9.48), root length (6.40 cm), new leaf growth on cuttings (59.05%) and field survival (96.98%) followed by Rosa banksiae. Performance of Rosa bourboniana was poor recording lowest values for all these parameters. Interaction effects were significant. NAA produced superior results in Rosa indica while, IBA gave promising results in Rosa banksiae and Rosa bourboniana. Growing medium significantly improved various rooting characteristics of cuttings. Superior results were obtained with sand 70%+ manure 30% which, recorded minimum days to root initiation (22.13), maximum rooting (83.33%), primary root number (15.52), root length (8.88 cm), new leaf growth (51.11%) and field survival (85.46%). Among the genotypes, Rosa indica consistently gave better results recording minimum days to root initiation (22.70), maximum rooting (90.00%), primary root number (21.21), root length (10.10 cm), new leaf growth (47.33%) and field survival (97.78%).
