this review article investigates a comprehensive description of the factors, methods, strategies, approaches and prerequisites influencing in vitro micropaopagation and the amount of their use across the world. the findings presented here are the results of the study of several hundred papers published all over the world. tissue culture techniques are routinely used for micropropagation. enhanc...
Background: Tissue culture is a new approach for production of secondary metabolites with many advantages over conventional methods. Elicitors such as nano particles are molecules that can stimulate the production of secondary metabolites. Objective: This study was conducted to evaluate the effects of some nano particles on mucilage production in Linum usitatissimum under tissue culture condit...
Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...
An efficient procedure for shoot regeneration was obtained by endosperm culture in Actinidia deliciosa cv. Hayward. Mature endosperm cultured on MS medium supplemented with 2 mg/l 2,4-D and 5 mg/l kinetin developed callus with 80% efficiency. Callus was transferred on MS medium containing different plant growth regulators (2,4-D, TDZ, IAA, NAA, BAP, kinetin, 2iP) for regeneration. There were si...
an efficient method for producing doubled haploid plants of date palm ( phoenix dactylifera l.) was established using in vitro colchicine treatment of anthers. to this study male inflorescences were harvested in the appropriate developmental stage. separated anthers after one day cold (4°c) pretreatment, in uninucleate stage of microspore were transferred to the modified y 3 medium containing d...
A rapid and efficient protocol was developed for inducing indirect organogenesis using leaf explants of Vitex negundo L. Explants were cultured on MS with different concentrations of 2,4-D and IAA in combination with BAP for callus induction. The frequency of callus induction increased with increasing concentration of IAA (0.3 mg/l) and BAP (0.3 mg/l) at optimal level. The shoot buds appeared e...
A simple method was developed to permit albino plant regeneration from anther culture of Hobigonj Boro (Hbj B) IV and Hbj B VI, two local varieties of aromatic indica rice from Bangladesh. Three crucial factors were identified for the albino shoot primordia to change into green plantlets in culture; components of M10 induction medium, callus size (range 0.2-0.4 cm long) and height of shoot prim...
This study was conducted to evaluate the responses of Iranian commercial genotypes of maize (hybrids and their inbred lines) to callus induction and plant regeneration, using mature embryos. Twenty five genotypes comprising of 12 inbred lines, 11 single cross hybrids, 1 double cross hybrid and 1 composite cultivar were used. Mature embryos of the genotypes were plated on MS and N6 media. Callus...
The present study is based on the in vitro production of callus, its long period maintenance and antibacterial potentiality. Callus induction and formation occurred by full strength MS media in combination with various concentration (0.5mg/l, 1.0mg/l, 1.5mg/l, 2.0mg/l) of 2, 4-D effective in combination with constant concentration of BA (2.5mg/l) and NAA (0.5mg/ml). The leaf calli were sub cult...
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...
