explants of leaves, petals, anthers, styles and ovaries of c. speciosus, c. cancellatus, c. gilanicus and c. almehensis were cultured on ls media with three different combinations of naa and bap in the dark. callus and neoformant organs (leaf and corm-like structure and ordinary and contractileroots) were fomd on some of these explants. corm explants from these species were also cultured on ms ...
For thousands of years, secondary metabolites have been utilized as medications, flavors, pesticides, and dyes. the generation valuable metabolites, in vitro plant culture techniques viewed beneficial alternatives to whole plants. Brugmansia suaveolens is an ornamental including anticholinergic agents which are employed medicine. Callus induction was performed from leaf internode explants cultu...
In the present study, stigmasterol has been reported from Pedalium murex L. of pedaliaceae family in vivo and in vitro. Quantification data revealed that the total sterol content was higher in callus than leaves. The in vitro studies showed that the maxmium amount of total sterol was found in 6 weeks old tissue and minimum in 2 weeks old callus culture. In vivo studies showed that higher conten...
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...
Persian shallot, also called leek (Allium ampeloprasum), is a monocotyledon plant of the lily family (Liliaceae). It belongs to the genus Allium, has a characteristic taste and morphological features, making it to be considered as one of the popular herbal medicine. This research was conducted with the purpose of obtaining optimal conditions for tissue culture of Persian shallot and comparing i...
cycas reveluta thunb. is a valuable ornamental plant, requiring special care for appropriate growth and development. this beautiful plant having been found for the first time in china, is typical in tropical areas. considering the advantages of tissue culture for propagation of the plant, the present study was aimed at evaluating the effects of various kinds and concentrations of growth regulat...
The ethanolic extracts of aerial shoots of Mollugo cerviana and its leaf derived callus were tested for antimicrobial activity using the filter paper disk assay method. Both the extracts showed antibacterial activity against Bacillus subtilis and Escherichia Coli. The antifungal activity of the extracts against Aspergillus niger and Aspergillus flavus was nil or negligible.
Among nematodes parasitizing bananas throughout the world, Radopholus similis and Helicotylenchus multicinctus are the most widespread and damaging species. Besides these two nematodes, Hoplolaimus pararobustus is encountered frequently in Ivory Coast and has been increasing in banana growing areas for the past 25 years (6,10). In vitro culture systems could facilitate screening for resistance ...
Purslane (Portulaca oleracea L.) contains valuable ingredients such as dopamine, noradrinalin and omega-3. The increase of secondary metabolites by elicitors is widely used in tissue culture of medicinal plants. The aim of this study was to assess effect of plant growth regulators on callus induction and amount of dopamine in callus tissue of purslane under the influence of methyl jasmonate as ...
The essential oils (EOs) and static headspaces (HSs) of in vitro plantlets and callus of Mentha x piperita were characterized by GC-MS analysis. Leaves were used as explants to induce in vitro plant material. The EO yields of the in vitro biomass were much lower (0.1% v/w) than those of the parent plants (2% v/w). Many typical mint volatiles were emitted by the in vitro production, but the call...
