During saffron (Crocus sativus) spice production, large amounts of floral biowaste are generated. It was the aim of this study to develop a value-added product from saffron floral biowaste to be used as a natural cosmetic ingredient. HPLC-PDA-MS analysis of saffron flower extracts revealed the presence of flavonols with the highest amounts in the acetone extract. Kaempferol-3-O-sophoroside was ...

Submit Manuscript | http://medcraveonline.com main component of flower color is anthocyanin, a type of flavonoid [1]. Numerous genes involved in anthocyanin biosynthesis have been analyzed in various plants, and their biosynthesis pathways determined [2,3]. In addition to anthocyanins, flavonols and organic acids also play a role in flower color as ‘co-pigments’ [4]. Fragrant cyclamen cultivars...

BACKGROUND Children of workers exposed to pesticides are at risk of secondary pesticide exposure. We evaluated the potential for lower acetylcholinesterase activity in children cohabiting with fresh-cut flower plantation workers, which would be expected from organophosphate and carbamate insecticide exposure. Parental home surveys were performed and acetylcholinesterase activity was measured in...

Computer Graphics (CG) and Virtual Reality (VR) technologies have rapidly improved in recent years. It enabled us to develop some useful systems such as air hockey, catch ball, tennis and horseback riding for sports field, surgical simulations and support systems for medical field, calligraphy and flower arrangement for educational field. The good training systems have force feedback for users ...

Surrogate pollen induction (SPI) was evaluated on loblolly pine (Pinus taeda L.) donor scions from 5-year-old progeny that were grafted by topworking into the lower crowns of 16-year-old loblolly pine receptor clones in a seed orchard. On each of 25 study trees, one of three pollen induction treatments (wire girdle, saw girdle or control) was applied to 10 receptor branches below the graft loca...

Genetic improvement of garlic through conventional breeding is very difficult due to sterile nature of its flower. Hence, an alternative system is desirable to induce genetic variation. Tissue culture could be a good opportunities and somatic embryogenesis is one of the potential techniques of tissue culture for in vitro regeneration of garlic plant. The successes and production of somatic embr...

Black mustard, Brassica nigra, is highly variable in both constitutive resistance and induction response following damage by herbivores. A focal population from Ithaca, New York, was used to test the following two predictions of optimal defense theory: (1) that allocation to resistance will reduce plant performance in the absence of herbivores; and (2) that induction response will be negatively...

A screen for mutations affecting flower formation was carried out and several filamentous flower (fil) alleles were identified. In fil mutants, floral primordia occasionally give rise to pedicels lacking flowers at their ends. This defect is dramatically enhanced in fil rev double mutants, in which every floral primordium produces a flowerless pedicel. These data suggest that the FIL and REV ge...

We searched for bioactive substances involved in flower bud formation of Arabidopsis thaliana. some significantly decreasing HPLC peaks were detected in the extract of flower buds-forming A. thaliana compared with that of the non-flower bud-forming stage. Compound 1, which corresponded to the most decreased HPLC peak, was isolated from aerial parts of A. thaliana. From NmR and ms data, compound...

This Paper aims at classification of flower images by means of Gist descriptor and statistical features using SVM classifier. With advances in digital image processing, automated classification of flower images over large categories of dataset is possible by knowing the name of the flower. In case of unknown species name, classification of flower image can be performed by its visual content. Th...
