Selection of Garden Roses to Improve the Ecosystem Services They Provide

With pronounced morphological and phenological diversity, garden roses have always been part of urban plantings. The significance in ornamental utilitarian (edible) horticulture can significantly be amended with novel ecosystem services, by shifting their breeding targets towards more than aesthetic nutritional value. Thus the aim this paper was to investigate possibilities newly bred (within past decade) from ‘Mella’ series as a possible ornamental, disease tolerant bee attracting cultivars recommended ecosystems, adding values current services. Research goals were determine characteristics; honey wild bees’ abundance its correlation rose floral resistance/tolerance main fungal diseases; suitability greenery providing multiple Plant material included seven series. Analyses complete morphological—qualitative quantitative characterization plant flower traits, fragrance panel scoring volatile components analyses, counts bees visiting flowers different species potential pollinators. Based on obtained results significant variability vegetative generative characteristics noted investigated roses. ‘naturalistic’ overall appearance, comparable roses, differed height habitus, number type flowers, leaf coloration glossiness, but ‘Barbie Mella’ ‘Ruby positioned most decorative ones. highly scored for fragrance, divergent records mixed compounds, characterized balanced ratio (almost 1:1:1) between aromatic alcohol + terpenoids, straight-chain alkanes long-chain alkanes. In relation bee’s attraction, combination height, (single, simple), diameter accessibility seems crucial, rather any characteristic solely. As an outstanding bee-attractor should promoted disease-tolerant cultivar. Due values, tolerance visitations, ‘Barbie’, ‘Ruby’, ‘Ducat’ ‘Exotic’ planted semi-natural gardens/landscapes, concomitantly contributing services—provisioning, regulating, cultural supporting. Until worldwide availability, other ‘Mella’-like cultivated likewise.
