3D flower models are important components for impressive virtual reality environments. However, flowers’ leaves or petals are 3D free curved-surfaces and they are very difficult to model. We present a user interface with which the user can easily model flowers using freehand sketches. The user interfaces for generation, transformation, and copy are specialized to model leaves and petals, and th...

Sainpaulias are among the most popular flowering plants and there are so many variations in flower shape, size and color. Aqueous solutions of 0 M to 10 M concentrations of salicylic acid (SA) were foliar-applied on two African violet cultivars to evaluate the influence of different rates of SA on growth and flowering of plants. The solutions were applied to leaves of plants 14, 21, 28 and 35 d...

We isolated two transcription factor genes, heterotrimeric G protein beta 2 subunit (Gβ2) and ArcA1, from pepper (Capsicum annuum). The complete coding sequences were amplified using reversed transcriptase PCR based on conserved sequence information of Solanum lycopersicum and several other plant species. Nucleotide sequence analysis of these two genes revealed that the pepper Gβ2 gene encodes ...

Pink Petuniahybrida (cv Hit Parade Rosa) corollas were found to contain photosynthetically active chloroplasts. The corolla chloroplasts were similar to those of green leaves in size and structure. The chlorophyll (Chl) content of Petunia corollas increased during early stages of flower development, reaching a maximum just before anthesis. Chloroplasts isolated from corollas at this stage, carr...

We investigated whether the Arabidopsis flower evolved protective measures to increase reproductive success. Firstly, analyses of available transcriptome data show that the most highly expressed transcripts in the closed sepal (stage 12) are enriched in genes with roles in responses to chemical stimuli and cellular metabolic processes. At stage 15, there is enrichment in transcripts with a role...

conclusions according to antioxidant activity outcomes, the amount of ic50s of aqueous extracts of flower and stem and also butylated hydroxyl toluene (bht) as standard were 232.34, 63.25 and 45.59 ppm respectively. ultimately, it was highlighted that antioxidant activity of aqueous extract of flower was weaker than stem. results sixty one compounds were identified in the essential oil of the f...

Iron administration to iron-starved cocklebur (Xanthium pensylvanicum) plants causes an increase in the iron content of ferritin fractions extracted from mature leaves. Xanthium plants grown under long days (vegetative stage) have more iron and ferritin than similarly iron-treated plants induced to flower under short day regimes. This first demonstration of ferritin in cocklebur (Compositae) le...

Honeysuckle (Lonicera japonica Thunb.) is a traditional medicinal plant in China that is particularly rich in chlorogenic acids, which are phenolic compounds with various medicinal properties. This study aimed to examine the effects of salinity stress on accumulation of chlorogenic acids in honeysuckle, through hydroponic experiments and field trials, and to examine the mechanisms underlying th...
