The genus Rosa has a wide variety in Iran and although some natural hybrids have been found in different regions of the country, but no cultivars have been established so far. In order to optimize use of genetic resources in the country and to create varieties with desirable traits, inter-species relationships and identification of diversity, 45 populations from seven species in sectio...

Discussing two short stories by contemporary Scottish author Ali Smith, my article recommends a close reading of prose narratives as potential examples ungendered character-narration. I combine queer and unnatural narrative theory to consider how forms telling contribute gender ambiguity. Further, advocate interpretative strategies that resist naturalization causal explanations. Instead, Smith’...

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...

Roses have an indisputable leading role in private gardens. They also appear public areas. are very interesting plants for urban areas because they represent aesthetic, ecological, tehnical and sociological potential. In varietes selected according to various criteria such as resistance heat, low temperatures drought, repetitive flowering ease of maintenance. The aim our study is present prefer...

This study aimed to analyse the phenolic composition of wild fruits of Arbutus unedo (strawberry-tree), Prunus spinosa (blackthorn), Rosa canina and Rosa micrantha (wild roses). Analyses were performed by HPLC-DAD-ESI/MS. P spinosa fruits presented the highest concentration in phenolic acids (29.78 mg/100 g dry weight), being 3-O-caffeoylquinic acid the most abundant one, and flavone/ols (57.48...

A novel, scalable, solution-based method suitable for the control of ZnO crystal morphology at moderate temperature from rods/stars to rose-shaped, flowerlike structures is presented here. The synthesized ZnO roselike crystals are composed by wide nanosheets folded several times on themselves. This study represents the first step toward the full understanding of the growth mechanism that led to...

The effect of exogenous salicylic acid (SA) on the vase life of cut rose flowers was investigated. ‘Yellow Island’ roses were obtained from a commercial grower. The roses were pulse treated with SA (0, 50, 100, 150, 200 mg l) for 18 hours. Compared to the control treatment (DW), the greatest delay in senescence was obtained in cut roses treated with 150 mg l SA. With this treatment, flower vase...
