Application of biotechnology for production and enhancing of important secondary metabolite by plant cell cultures and elicitors is one of the most noteworthy researches by scientists. This research was carried out with the aim of analysis the effects of Vanadyl Sulfate (abiotic elicitor) on media consumption by Satureja khuzistanica cells under suspension culture. Cells obtained after four sub...
In vitro budinduction and shoot regeneration of Lantana camara L. was investigated using axillary nodal explants. Multiple shoot buds were induced on Murashige and Skoog (MS) media supplemented with 0, 2, 4 and 8 mg/l of 6-benzylaminopurine (BAP) or thidiazuron (TDZ) for proliferation and 0, 0.25 and 0.5 mg/l indole-3 butyric acid (IBA) for rooting. After 4 weeks, a maximum number of shoot buds...
Abstract Background: Due to the high prevalence of leishmaniasis andthe importance of the culture method in Leishmania research, and the vital need to the fetal calf serum (FCS), which is normally used in the media and difficulties associated with the use of this material such as the high cost, the possibility of viral contamination and the difficulty of import, the potency of bovine, sheep or ...
Nowadays, many researches were conducted in minimizing tissue culture technology due to the overhead of cost needed. The purpose of this study was to investigate the effects of using five kinds of organic additives at four level concentrations responsive to the number of shoots produced for eight weeks in culture. Stem segment explants of Celosia sp. were cultured on MS medium that have been su...
In vitro cormogenesis is a potential tool for improving saffron production under controlled conditions. this study, the effects of explant type, culture and medium supplements on daughter corm formation in were assessed. Saffron flowers emerged 30 days after culture, sizes in-vitro- ex-vitro-produced stigmas similar. life cycle was completed 10 14 weeks respectively. Using intact corms more eff...

organogenesis and neoformant plantlet production were studied by culturing the different parts of mature embryo including radicle and proximal and distal parts of cotyledon of mission and kroneiki cultivars. different parts of embryos were cultures in omc medium containing growth regulators, such as indole butyric acid (iba) and 2-isopentenyl adenine (2-ip) or iba and naphthalene acetic acid (n...
The Silybium marianum is the dicotyledonous herbs of the Asteraceae family that is important in medical industry. The biological active compound of Silybium marianum is a mixture of several flavonolignals generally known as silymarin. The purpose of current research is root formation induction in hypocotyls explants in medium culture. The young shoots were cultured on MS medium containing diffe...
