The growth rates of tobacco callus tissues on media containing 10(-6) to 10 mum 6-(gamma,gamma-dimethylallylamino)purine (2iP) were measured. At concentrations of 10(-4) mum and above growth rates were exponential and dependent on cytokinin concentration. At 2iP concentrations of 10(-4) to 0.33 mum, the exponential rate was maintained for 4 to 5 doublings of fresh and dry weight. After this per...

this research was conducted to study the factors affecting establishment, growth and shoot proliferation of persian walnut, genotype z60. explant establishment was studied through a factorial experiment based on a completely randomized design with two factors including culture media (dkw and wpm) and ba concentration (0 (control), 0.5 and 1.0 µm). single-node explants were prepared from the you...

among pome fruit trees, quince is the most susceptible tree to fire blight. following selection of several promising quince cultivars, this research aimed at optimization of in vitro propagation protocol of the selected materials. therefore, several experiments were carried out for determination of the best culture medium and plant growth regulators for establishment, proliferation and root ind...

in order to micropropagate of four vigorous rootstocks of pear, including pyrus betulifolia, konjuni, dargazi and gh1, effects of basic plant culture media (ms, ql and modified ql), cytokinins and auxins on productivity, proliferation and rooting were studied in seed and plant improvement institute, karaj. the highest amount of productivity for all rootstocks was observed in ql medium. among pe...

In vitro culture has become a dependable approach for the mass production of plant material as market innovative plant-derived medicinal approaches grown significantly. Furthermore, because it permits manipulation biosynthetic routes to boost and accumulation certain compounds, this technology enormous potential manufacture natural bioactive chemicals. As result, goal study was develop an effic...
