in this study, responses of four canola genotypes to salt stress in germination test and callus culture stages were investigated. the response of genotypes under salinity levels was significantly different. higher salinity resulted in less germination and growth of seedling. after callus culturing on liquid saline media, callus fresh weight and callus induction efficiency were significantly dif...

we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...

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...

plant tissue culture techniques were used to study the effect of nacl on tropane alkaloids accumulation and proline content of both datura metel and datura stramonium. callus cultures were established for both datura species. however, ms medium supplemented with 1mg/l of both ba and naa was the best for callus production in d. metel, while ms supplemented with 3 mg/l kin and 1 mg/l 2, 4-d was t...

Unselected and sodium sulfate tolerant callus cultures of Brassica napus L. cv Westar were grown on media supplemented with mannitol, NaCl, or Na(2)SO(4). In all cases, growth of tolerant callus, measured on a fresh weight or dry weight basis, was greater than that of unselected callus, which was also subject to necrosis on high levels of salt. Tissue water potential became more negative in bot...

to explore the potential for in vitro rapid regeneration of fagonia indica burm., cotyledon explants were obtained from 10-day old aseptically germinated seedlings that cultured on ms medium which supplemented with 1.0-5.0 µm 2,4-d. callus was initiated from cotyledon explant on ms medium supplemented in all concentrations of 2,4-d investigated. 2,4-d was more effective than iaa and naa for cal...

An efficient system was established for high frequency embryogenesis and regeneration of indica rice, Oryza sativa L. cv. MDU 5. Basic media, carbohydrate sources and concentrations, agar concentrations, amino acids, cytokinins and auxins were evaluated in callus induction and regeneration media to establish the most efficient regeneration protocol for MDU 5 indica rice. The optimized callus in...

   Present study has comparatively investigated the effect of zinc oxide nanoparticles (ZnO NPs), ZnO bulk particles (BPs), and relevant metal ions (Zn2+) on the tissue culture of rapeseed (Brassica napus L.) to properly evaluate the impact of ZnO NPs on callus induction. For finding the best hormonal combination for inducing callus, hypocotyl explants were cultured on Murashige ...

The effect of different media including the growth regulators on somatic embryogenesis from Mexican lime was studied. The average embryo formation after 60 days from unfertilized ovules in different media was evaluated at 0 to 33.75%. The most effective hormone to stimulate embryogenesis was GA3 at 0.01 and 0.1 mg/l concentrations. Malt extract (ME) at 300 mg/l increased embryo formation, where...
