Hybridization with introduced genetic resources is commonly practiced in ornamental plant breeding to introgress desired traits. The 19th century was a golden age for rose breeding in France. The objective here was to study the evolution of rose genetic diversity over this period, which included the introduction of Asian genotypes into Europe. A large sample of 1228 garden roses encompassing th...
International trade involves crossing several organizational boundaries. This revelatory case study follows fresh cut roses’ journey from the growers in Kenya to the retail distribution in Holland and shows relatively high barriers related to the associated activities, information and documents, etc. Our empirical findings reveal the serious limitation that existing inter-organizational system ...
Orcinol O-methyltransferase (OOMT) 1 and 2 catalyze the last two steps of the biosynthetic pathway leading to the phenolic methyl ether 3,5-dimethoxytoluene (DMT), the major scent compound of many rose (Rosa x hybrida) varieties. Modern roses are descended from both European and Chinese species, the latter being producers of phenolic methyl ethers but not the former. Here we investigated why ph...
In order to study the effect of external ethylene on postharvest display and activity of some senescence-related enzymes in potted miniature roses, this experiment was carried out in a completely randomized design, using three treatment levels with three replications. In glass chambers, potted miniature rose plants were exposed to ethylene concentrations of 0, 5 and 10 μL L-1 for 12 h. The resu...
Roses are commonly known for their ornamental looks and usage in the perfumery industry. There many types of roses available some them rarely found, which limits opportunity people to recognize learn about them. Thus, Learning About Types Using Augmented Reality is developed focuses on learning species, color using mobile augmented reality technology. The project's main goal provide an alternat...
The postharvest vase life of cut roses was studied to determine the effects of various physiological factors that influence the vase life of cut flower. Cut roses were obtained from commercial area of Siliguri. To assess the effect of preservatives on the postharvest life of rose, cut flowers were treated with following preservative solutions: fixed amount of citric acid (CA) (300 mg/ml) and 8-...
