Gloriosa superba L. a medicinally important monocot, member of the family Liliaceae, was investigated for callusing, direct regeneration and induction of hairy root using soil bacterium Agrobacterium rhizogenes. Friable callus was initiated from corms on basal MS medium amended with 2,4-D (1 mg L) and kinetin (1 mg L). Callus generated from such effective combinations were co-cultivated with th...
Calluses from seasonal mature shoots of Taxus globosa Schltdl. were subcultured in new medium containing 1 mg l -1 NAA, 0.5 mg l -1 2, 4-D, 0.025 mg l -1 BA. Calluses growing for 30 and 40 days in a medium added with 0.1-5.0 mg l -1 of chlorocholine chloride (CCC) were harvested for determination of taxol, phenolic compounds, and for polyphenol oxidase (PPO) activity. The results showed that by...
In vitro regeneration of four cultivars of carnation namely ‘Nelson’, ‘Impulse’, ‘Sagres’ and ‘Spitit’ through somatic embryogenesis was studied. MS culture medium was supplemented with 30 gl-1 sucrose, 2 mgl-1 2,4-D and 0.2 mgl-1 BA and used for embryogenic callus formation. Somatic embryos were formed when embryogenic callus was transferred to MS medium without growth regulators containing 30...
Tomato (Lycopersiconesculentum Mill. cv. Rampai) is rich in lycopene, a carotenoid group compound with many biological activities, one of which as an antioxidant. Conventional tomato cultivation not optimal due to the susceptibility plants pests and diseases, even though need for lycopene continues increase. Plant tissue culture method can be solution production. Callus Rampai was initiated fro...
It has been observed in this laboratory (15) that the normally polar distribution of callus growth on tobacco stem explants becomes non-po'ar in the presence of low levels of 2,3,5-triiodobenzoic acid (TIBA), while the amount of callus growth is not diminished. It was thought that this phenomenon might reflect a specific inhibition by TIBA of the polar transport of auxin. Subsequent studies (10...
Cereus peruvianus (Cactaceae) is an important medical plant. The study was carried out on callus induction of Cereus jamacaru f. monstrosus and Cereus hildmannianus fma monstrosa (Cereus peruvianus). Apical and lateral explants were cultured on Murashige and Skoog media with factorial combinations of the auxins indole-3acetic acid (NAA), 2, 4-dichlorophenoxyacetic acid (2,4-D) and N-(2-furanyl-...
echium amoenum fisch. and c.a. mey. (boraginaceae) is a very popular medicinal plant which is used as a tonic, tranquillizer, diaphoretic, cough remedy, sore throat and pneumonia in iran’s traditional medicine. callus culture of medicinal plants is one of the ways for production of secondary metabolites. in this study, callus culture of e. amoenum and its major secondary metabolite were investi...
The aim of this study was to produce sugarcane plantlets from cell suspension culture and study its genetic fidelity using molecular markers. The study was carried out using sugarcane varieties Co 86032 and Q117. Callus cultures of both the varieties were optimized using six different callus induction media. After screening the growth response of callus on six different callus induction media, ...
Ethanolic extract of root and root derived callus extracts of Premna serratifolia L were investigated against paracetamol induced oxidative stress and hepatotoxicity in blood and liver of male albino rats. The root explants were cultured on MS medium supplemented with various combination and concentration of plant growth regulators. The best callus biomass was observed from the MS medium supple...
background: ferula gummosa boiss. is a medicinal and economical plant belonging to apiaceae family. it is a native herb of iran and is in serious danger of extinction. objective: gamma irradiation is an environmental stress and can consider as a new tool to change the content of secondary metabolites in medicinal plants. the effect of gamma irradiation on phenolic content and radical scavenging...
