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 optimize the application of nutritive solutions and phytosanitary treatments with direct influence on quality cut roses from hydroponic culture (soilless culture), it is necessary study biochemical composition different organs plant (leaves). By FT-IR spectroscopy using standard KBr pellet technique; was possible differentiate between 10 Rosa cultivars based chemical leaves also ide...

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-...

Dog rose (Rosa canina) has been using as a rootstock for ornamental roses also it is one of the medicinal plants. It can be propagated under in vitro conditions. After removing chilling requirement of buds, axillary wood buds of dog rose were cut in three nodal positions (lower, middle and terminal) on the stem and then explants after decontamination, cultured on Murashige and Skoog medium (MS ...

We observed diel vertical migration patterns in juvenile pink salmon (Oncorhynchus gorbuscha (Walbaum, 1792)) and tested the hypothesis that fish behaviour is altered by exposure to sea lice copepodids. Experiments involved replicated field deployments of a large (9 m) plankton column, which provided a vertical distribution enclosure under natural light and salinity conditions. Diel vertical di...

Sir—Drawing ability could be disrupted by many neurological disorders, of which graphic neglect after unilateral brain damage (generally of right parietal cortex) is most frequent. In this disorder, patients draw preferentially on the right side of the paper, omit and deform objects on the left side, but judge their drawings to be complete. Graphic neglect can become especially evident in the w...
