Roses, both fresh and dried, often appear during festive occasions. However, roses do not last long, dried flowers are marinated with environmentally unfriendly chemicals. This paper proposes the procedure experiment of drying by freeze-drying method. After proposed method, results show that rose color changes very slightly but still retains its natural, eye-catching, friendly appearance.

Flower scent is an important trait of ornamental roses and has been character in the selection processes. In present study, composition volatile organic compounds (VOCs) emitted by both petals pollen 21 garden (Chinensis, Climber, English rose, Floribunda, Hybrid Tea, Multiflora, Damascena, Musk Polyantha, Rugosa Shrub) was investigated through GC-MS Static Headspace method. A total 19 differen...

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...

Comparison in the RGB domain is not suitable for precise color matching, due to the strong dependency of this domain on factors like spectral power distribution of the light source and object geometry. We have studied the use of multispectral or hyperspectral images for color matching, since it can be proven that hyperspectral images can be made independent of the light source (color constancy)...

Forty-four taxa of three sections (Cinnamomeae (=Rosa) 26, Chinenses 8 and Gallicanae 10) and eight modern garden roses in the genus Rosa were surveyed for their floral anthocyanins. Eleven anthocyanins: 3-glucosides and 3,5-diglucosides of cyanidin (Cy), pelargonidin (Pg) and peonidin (Pn), 3-rutinosides and 3-rho-coumaroylglucoside-5-glucosides of Cy and Pn, and Cy 3-sophoroside, were isolate...

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...
