Abstract
Stenting is a grafting technique for quick propagation of greenhouse rose plants all year round based on bench-grafting of a leafy scion with a dormant bud on a single internode stem cutting of the rootstock and rooting under mist. Formation of the graft union and rooting occurs simultaneously, resulting in a complete plant in 3 weeks. The present study reports results on the potential of using the bench T-budding as an alternative technique to propagate greenhouse roses under mist. Stem cuttings of the rose cultivar ‘Akito’ with a leaf and a dormant bud were grafted on defoliated or on single leaf cuttings of the rootstock Rosa indica ‘Major’, by the “stenting” technique. In further treatments scions with a dormant bud of the same cultivar ‘Akito’ were T-budded on single or two leaf cuttings of the above-mentioned rootstock Rosa indica ‘Major’. The rootstock cuttings were treated with 2500 mg l-1 IBA solution and rooted in a mixture of 3 : 1 perlite : peat under mist. The percentage of successful unions was higher in the T-budded plants in both seasons. The presence of two leaves increased the percentage of successful rooting, especially of the stented cuttings, and the mean number of roots in both grafting methods. Bud breaking occurred later in the T-budded cuttings. During the first year of greenhouse cultivation in pots productivity and quality of flowers of the budded plants were not statistically different from in the grafted plants.
