In the cut flower market, traditional breeding is still the best way to achieve new rose cultivars. The geographical delocalization of cultivar constitution (generally made in Europe and North America) and plant cultivation (large areas in Africa and South America) represents a limit point for crossing and selection. Rose breeders often need to overcome geographical distances, resulting in asyn...

zThe coding sequence is compared for each pair of genes. Comparisons were done using the gap program of the Wisconsin GCG sequence analysis package. yCHS = chalcone synthase; CHI = chalcone isomerase; DFR = dihydroflavonol reductase. xFirst row for each plant pair presents the percent amino acid similarity. wSecond row for each plant pair presents the percent amino acid identity. vThird row for...

Rose (Rosa hybrida L.) is one of the mostly cultivated cut flowers in Iran and around the world. The study was carried out to increase the vase life and quality of cut rose ‘Grand Prix` and ‘Avallanche` by using various floral preservative solutions. Floral preservative solutions were AgNO3, 8-HQS, nano silver and distilled water. Treatments were compared with tap water as control. The experime...
