establishment of an efficient and reproducible regeneration protocol is one of the basic prerequisites for genetic transformation of any crop plant. in vitro culture of lentil has proven to be difficult. in spite of a number of reports on the regeneration of this plant, very few satisfying and reproducible protocol has yet been reported. this study carried out for investigation of different hor...
Natural regeneration ensures the survival of forest stands and sustainable forest development. The present study was conducted to investigate the natural regeneration of Persian oak (Quercus macranthera fisch. & C.A.Mey. Ex Hohen) stands in Arasbaran protected forest. Measurement of the frequency of standard and coppice regenerations was carried out in one-hectare square plots (100 × 100 m) in ...
transverse thin cell layer sections excised from in vitro scales of lilium ledebourii were cultured on murashige and skoog (ms) medium supplemented with various plant growth regulators (pgrs) at different concentrations. although, bulblets were produced on pgrfree ms medium during organogenesis, addition of 0.25 mg l-1 6-benzyladenine or 5.0 mg l-1 indole-3-acetic acid to the medium increased t...
The search for effective strategies for peripheral nerve regeneration has attracted much attention in recent years. In this study, ordered collagen fibers were used as intraluminal fibers after nerve injury in rats. Vascular endothelial growth factor (VEGF) plays an important role in nerve regeneration, but its very fast initial burst of activity within a short time has largely limited its clin...
Xerostomia or feeling of dry mouth is the most common (80%) all complications radiotherapy for head and neck cancer. Besides well-known artificial saliva agents therapies stimulating production salivary gland regeneration, new methods comprise use vitamins C E, low-level laser therapy, hyperbaric oxygen therapy thyme honey. Recently, transplantation mesenchymal stem cells was reported to be suc...
Abstract In order to explore the development path of Hunan embroidery under vision artificial intelligence, promote digital regeneration and database construction stitches, communication, interaction between brands public, create more possibilities for revitalizing culture industrial non-heritage embroidery. this paper, a mechanics model stitch is established based on finite element idea view i...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
