leaf and root explants from 10 to 20 day– old seedlings of plantago lanceolata, were cultured on ms, msh, nt and b5 basal media with various concentrations of different plant growth regulators. the best callus induction was obtained with 0.4 mgl-1 2,4-d in msh i with 400 callus index. callus growth was significantly stimulated (p=0.05)with 0.8 mgl-1 2,4-d and 0.1 mgl-1 kin in msh ii, with 7...

abstract gerbera is one of the most demanded plants in commercial cut flowers plants. optimizing the micro-propagation of new cultivars is therefore important. in this research “red explosion” cultivar was used and capitola (as explants) were directed to a modified solid murashigue and skoog medium with four concentration of tdz (0.25, 0.50, 0.75 and 1.00 mgl-1) for regeneration. three concentr...

given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. this study was conducted during 2012-2013 at the research center of agricultural university of tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. a...

aflatoxins (afs) are one of the most important mycotoxins due to their common occurrence in feedstuffs and feeds that pose a serious threat to humans and animals. although many outbreaks of acute and chronic diseases have been attributed to consumption of aflatoxin-contaminated foods, the most significant effect of aflatoxin is hepatotoxicity in farm animals, especially aflatoxicosis in shrimps...

an important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. nowadays, the use of compounds such as essential oils (eos) and nanoparticles is applicable in microbiology studies. the main objective of this experiment was to study the s...

abstract this experiment was conducted for optimizing a suitable medium for callus induction, regeneration and rooting of anthurium. leaf and petiol explants of antadra and casino varieties were used for callus production. ms medium was supplied with growth regulators (naa, ba, kin and iba). a complete randomized design with 3 replication was used in this expriment. result indicates that variet...

in this study, physiological and morphological responses of five almond cultivars to drought stress were investigated under in vitro conditions. plantlets from five commercial almond cultivars (supernova’, ‘tuono’, ‘sahand’, ‘ferragnes ’ and ‘shahroud 21’] were established in ms medium containing 0.5 mg per liter bap and then subcultured  in ms proliferation medium containing 1 mg per liter bap...

who recommends artemisinin-based combination therapies (acts) as the most effective choice to treat malaria. for developing transgenic plants with high accumulation of artemisinin (by introducing genes encoding enzymes which regulate the biosynthetic pathway of artemisinin), an efficient protocol for tissue culture and plant regeneration is necessary. in the present study, leaf explants of arte...
