Flower opening is a process that requires movement of petals from a closed position to a horizontal open position, while petal abscission requires cell-wall disassembly. Both processes are controlled by ethylene and require cell-wall modification at the junction (abscission zone) of the petal and thalamus to facilitate the movement or separation of petals. In the present study, a family of xylo...

light intensity is considered a limiting factor in greenhouse rose production. the main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (rosa hybrida cv. avalanche), under greenhouse conditions. the experiment was planned in randomized completely block design with four replications. all shoots we...

Garden rose, Rosa hybrida, is primarily used for decoration and has a wide range of growing area, contrary to R. damascena that limited area distribution (Turkey Bulgaria), yet it extensively commercial production valuable expensive rose oil. Since the content essential oil in petals low (0.03–0.04%), its quite limited; however, during this process, significant amount hydrosol obtained as secon...

Fifteen compounds were extracted and purified from the leaves of Nelumbo nucifera Gaertn. cv. Rosa-plena. These compounds include liriodenine (1), lysicamine (2), (-)-anonaine (3), (-)-asimilobine (4), (-)-caaverine (5), (-)-N-methylasimilobine (6), (-)-nuciferine (7), (-)-nornuciferine (8), (-)-roemerine (9), 7-hydroxydehydronuciferine (10) cepharadione B (11), β-sitostenone (12), stigmasta-4,...
