Rosa foetida Herrm. is an important wild rose that contributed to the birth of modern yellow cultivars. It also well known for unpleasant odor, not prevalent in other roses, emanating from its petals. We analyzed floral scent R. and sport cultivars, var. bicolor (Jacq.) Willm. f. persiana (Lem.) Rehd., identify causative compounds their offensive odor. Fatty acid derivatives 2,4-decadienal (2,4...
in vitro propagation of rose (rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including indian subcontinent. the development of new cultivars for commerce is faced with new challenges. in vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...
In order to improve the postharvest quality and the export ability of cut rose (Rosa hybrida L.) cvs. Happy Hour and Bordeaux, the effect of 1-methylcyclopropene (1-MCP) as an ethylene inhibitor, was investigated. 1-MCP was used at 0.3, 0.4, 0.5 and 0.6 g m-3 for 18 h at 8 °C to simulate the transport of flowers. 1-MCP treatment significantly prolonged the vase life and minimized the weight los...
Rose flower (Rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. To study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of Alandasht, Astane Ghods Garden, Mashhad, Iran, during 2009-2010. The first factor was six cultivars of rose flower ...
For centuries, rose has been the most important crop in the floriculture industry; its economic importance also lies in the use of its petals as a source of natural fragrances. Here, we used genomics approaches to identify novel scent-related genes, using rose flowers from tetraploid scented and nonscented cultivars. An annotated petal EST database of approximately 2100 unique genes from both c...
