Roses (Rosa indica) belong to one of the most crucial groups of plants in the floriculture industry. Rosa species have special fragrances of interest to the perfume and pharmaceutical industries. The genetic diversity of plants based on morphological characteristics is difficult to measure under natural conditions due to the influence of environmental factors, which is why a reliable fingerprin...

The life table parameters of Macrosiphum rosae L. (Hemiptera: Aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on Rosa hybrida L. were determined under laboratory conditions. There were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. The highest mortalit...

El uso excesivo de agroquímicos para nutrir y controlar plagas encultivo rosa (Rosa x hybrida) conlleva costos ambientales económicos, por lo que se buscan alternativas disminuir su utilización. objetivo la presente investigación fue obtener un compost elaborado con vegetales aportan silicio y, evaluar efecto en cuatro ciclos productivos cv. Freedom®, sobre incidencia araña roja (Tetranychus ur...

Plant growth regulators (PGRs) play a key role in regulating physiological and morphological development of plant species. Application of these PGRs can improve preand post-harvest quality and quantity of ornamental flowers and lessen the harmful effects of injury incurred at harvesting time. The objective of this study was to determine the appropriate spraying solution for improving preand pos...

Scented rose species are very important in the genus Rosa due to their use in highly-prized essential oil production and as garden roses. The fragrance of the rose flower (attar) captured by extraction is one of the most valuable flavor and fragrance products. A comprehensive study of the papers published in the field of in vitro culture and biotechnology of these species, particularly Damask r...

Background: Damask roses (Rosa damascena Mill.) are mainly used for essential oil production. Previous studies have indicated that all production material in Bulgaria and Turkey consists of only one genotype. Nine polymorphic microsatellite markers were used to analyze the genetic diversity of 40 accessions of R. damascena collected across major and minor rose oil production areas in Iran. Resu...

Cut-flower production of Rosa hybrida ‘Kardinal’ and ‘Fire and Ice’ were compared between two canopy management regimes: shoot-bending and hedgerow without shootbending, and between hydroponics and non-hydroponic (UC Mix) culture with a tensiometer-based irrigation system. We observed the number and length of all harvestable flowering shoots from September 1997 to August 1999 in order to assess...
