In previous work, senescence of rose petal cells has been shown to be accompanied by a gradual decrease of membrane fluidity, as measured by a fluorescence polarization technique. Concomitantly, an increase in the free sterol-to-phospholipid ratio was found. Both observations were verified in this study. Further, experiments carried out on whole tissue and isolated protoplasts during senescence...

Abscission is a process that involves shedding of plant organs from the main plant body. In this study it is shown that the process of petal separation in the fragrant rose, Rosa bourboniana, is accompanied by the expression of two xyloglucan endotransglucosylase/hydrolase genes, RbXTH1 and RbXTH2. The sequences of the two genes show 52% amino acid identity but are conserved at the catalytic si...

Abstract Basic Health Report (2013) reports that burns rank sixth in unintentional injuries. Rose petals have various pharmacological effects can increase wound healing activity. In this study, the activity of using rose as an ointment was tested on 25 male wistar rats which were grouped into: control (Ointment base), standard (Nebacetin), 7.5%, 10%, and 15% petal doses, respectively. The made ...

The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporally with petal-inrolling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...
