Seasonal Variation in Floral Scent of Persian Musk Rose (Rosa moschata Hermm.)
The seasonal variation of volatile oil compositions (VOCs) from fresh flowers of Persian Musk rose was investigated by Combi PAL Headspace Techniques. In this study, a total number of 21 VOCs were detected by headspace on the Combi PAL System and gas chromatography-mass spectrometry (HS-GC/MS) from Rosa moschata Herrm. at different seasons which was representing 92.53-99.37% of total VOCs. The ...
متن کاملScent evolution in Chinese roses.
The phenolic methyl ether 3,5-dimethoxytoluene (DMT) is a major scent compound of many modern rose varieties, and its fragrance participates in the characteristic "tea scent" that gave their name to Tea and Hybrid Tea roses. Among wild roses, phenolic methyl ether (PME) biosynthesis is restricted to Chinese rose species, but the progenitors of modern roses included both European and Chinese spe...
متن کاملmolecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...

متن کاملPLANT VOLATILES. Biosynthesis of monoterpene scent compounds in roses.
The scent of roses (Rosa x hybrida) is composed of hundreds of volatile molecules. Monoterpenes represent up to 70% percent of the scent content in some cultivars, such as the Papa Meilland rose. Monoterpene biosynthesis in plants relies on plastid-localized terpene synthases. Combining transcriptomic and genetic approaches, we show that the Nudix hydrolase RhNUDX1, localized in the cytoplasm, ...
