Abstract Black plum sawfly ( Hoplocampa minuta ) is an important pest species of Prunus domestica ). In organic orchards, the yield loss caused by H. larval damage can reach almost 100% occasionally. Adults feed on pollen and nectar flower; therefore, we hypothesize that, besides visual cues, also olfaction plays role in habitat host finding. To understand chemical communication mediated flower...
Saffron Flower Extract Promotes Scratch Wound Closure of Keratinocytes and Enhances VEGF Production.
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 ...
A Review of Research on Flower-Colored Mutants of Fragrant Cyclamens Induced by Ion-Beam Irradiation
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 ...
تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
Vernicia fordii is a monoecious and diclinous species with male and female flowers on the same inflorescence. Low female to male flower ratio is one of the main reasons for low yield in this species. However, little is known of its floral development and sex determination. Here, according to the results of scanning electron microscopy and histological analysis, the floral development of V. ford...
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...
