embryogenic callus initiation from anther and whole flower explants in four grapevine cultivars including flame seedless, shahroodi, perlette and red sultanina cultured on piv and harst nutrient media was studied. results showed that whole flower explants of ‘flame seedless’ cultured on piv medium had the most potential for callus production. later callus were transferred onto ges1ca medium for...
Echinacea purpurea belongs to the family of Asteraceae which has different medicinal properties. The main goal of current research was optimization of callus induction and biomass production by using Response Surface Method (RSM). For this purpose, root and leaf explants were cultured in the ½ MS medium supplemented with different concentrations (0, 1 and 2 mg/L) of Kin either alone or with 2,4...
chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. we looked for the presence of this compound in the callus cultures of varthemia persica dc (var. persica ). we have evaluated the conditions for establishment of callus cultures of v. persica and the in vitro production of chlorogenic acid. callus was initiated ...
Studies were conducted on the effect of amino acids and growth regulators on the production of artemisinin, an antimalarial compound, in the callus of Artemisia absinthium. Callus was initiated on solid MS medium supplemented with BAP and NAA from leaf explant. For the production of artemisinin, the callus was proliferated on sterile filter paper bridge in MS medium supplemented with different ...
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...
Crataegus aronia is a wild medicinal plant belonging to the Rosaceae family and has been known for the medicinal activity of its extracts due to the high levels of flavonoids and phenolic compounds. Recently, in vitro culture of plant cells, callus and microshoots is widely used to maximize production of plant secondary metabolites. In this study, the effect of different light intensity levels ...
Chlorogenic acid, a pharmacologically important compound, is a phenolic compound that occurs in certain commonly used medicinal herbs. We looked for the presence of this compound in the callus cultures of Varthemia persica DC (var. persica). We have evaluated the conditions for establishment of callus cultures of V. persica and the in vitro production of chlorogenic acid. Callus was initiated b...
optimization of regeneration methods in cotton is necessary to improve and successful production of transgenic cotton cultivars by tissue culture technique. this study was conducted to determine the genotypic effect on callus induction in cotton using 3 genotypes (coker349, 4-s-4 and c1211) and coker 312 selected and a study was carried out in cotton research institute of gorgan using a factori...
Experiments were carried out for optimization of conditions for morphogenic callus production and regeneration of carrot (Daucus carota L.) using four cultivated cultivars in Iran. Hypocotyl segments were cultured on medium supplemented with 0.2 mg/l 2,4-D for callus initiation and proliferation. Small portions of calli (25 mg) were cut and transferred to new media with different concentrations...
INTRODUCTION To control the tissue browning phenomenon, callus growth, total phenolics and paclitaxel production, in the current investigation, we evaluated the effects of citric acid and ascorbic acid (as antioxidants) and glucose, fructose and sucrose in callus cultures of Taxus brevifolia. METHODS To obtain healthy callus/cell lines of Taxus brevifolia, the effects of two antioxidants asco...
