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...

abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...

lilium ledebourii (baker) boiss. (liliaceae) is a critically endangered lily species native tonorthern iran, where it is protected by law. in order to develop a cost effective method for largescalepropagation, the effects of three culture systems (solid, liquid and temporary immersion)and two types of cytokinins [6-benzyladenine (ba) and thidiazuron (tdz)] were studied onthe in vitro plant rege...

this review article investigates a comprehensive description of the factors, methods, strategies, approaches and prerequisites influencing in vitro micropaopagation and the amount of their use across the world. the findings presented here are the results of the study of several hundred papers published all over the world. tissue culture techniques are routinely used for micropropagation. enhanc...

norfolk island pine (araucaria excelsa) is belonging to araucariaceae family and is native to norfolk island in australia. this plant is a woody ornamental plant of high commercial value. since it is propagated by seed, achieving a regeneration system is one of the most important goals in this woody plant tissue culture. to evaluate the effect of cytokinins and culture media for bud induction d...
