BACKGROUND Plant-based traditional system of medicine continues to play an important role in healthcare. In order to find new potent source of bioactive molecules, we studied the cytotoxic activity of the essential oils from the flowers and leaves of Callistemon citrinus. This is the first report on anticancer potential of essential oils of C. citrinus. METHODS Cytotoxicity of essential oil w...
There are many image retrieval systems today. These systems, however, are difficult to use in outdoors. In this paper, we propose an image retrieval system of flowers that can be used for mobile computing environment. When we use this system, first we photograph a flower with a digital camera, put the flower image in a personal digital assistant (PDA) and give some simple characteristics of flo...
The effects of salicylic acid (SA) and Putrescine (Put), on cut Gladioluswas studied. SA (0, 150, 300 and 450 mg l-1) and Put (0, 100, 200 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 192 Gladioluscut flowers in horticulture laboratory of agriculture faculty of...

Overview Corals have been shown to harbor unique microbial communities associated with their surface mucopolysaccharide layer, which is hypothesized to play an important role in defense against invading pathogens (Ritchie and Smith, 2004). In this study, bacterial associates of Montastraea faveolata surface mucus were compared between the healthy, disease-free reefs of the Flower Garden Banks N...
Flower color is mainly determined by anthocyanins. Rosa hybrida lacks violet to blue flower varieties due to the absence of delphinidin-based anthocyanins, usually the major constituents of violet and blue flowers, because roses do not possess flavonoid 3',5'-hydoxylase (F3'5'H), a key enzyme for delphinidin biosynthesis. Other factors such as the presence of co-pigments and the vacuolar pH als...
In the present paper, we report on a simple and new approach for the synthesis of hierarchical flower-like zinc oxide superstructures ZnO (FL) in the presence of the TEMPO-oxidized cellulose gel (TOCgel) through a room temperature sol-gel process in aqueous medium. Resulting composite films based on TOCgel and ZnO were investigated by several techniques including scanning electron microscopy (S...
INTRODUCTION Engineered nanomaterials have received greater attention for their positive impact in improving many sectors of economy, including pharmaceutics, cosmetics, transportation, energy, agriculture and environment. Nanoparticles can drastically modify their physico-chemical properties compared to the bulk material, the improvement of experimental processes for the synthesis of these nan...
Susceptibility of the reproductive system to temperature fluctuations is a recurrent problem for crop production under changing climate. The damage complex as multiple processes in male and female gamete formation are affected, but general, particularly pollen impaired. Here, impact short periods elevated on meiosis tomato ( Solanum lycopersicon L.) reported. Meiocytes early stage flower buds e...
In order to improve quantitative and qualitative properties and vase life of rose cv. Dolcvita, an experiment was conducted in a randomized complete blocks design with ten treatments and three replications in a hydroponic greenhouse adjacent to Yasouj city, Iran. Treatments included control, spermidine (0.5, 1 and 1.5 mM), calcium sulfate (2.5 and 5 mM), spermidine 0.5 mM+ calcium sulfate 2.5 m...
