بررسي تاثير غلظت هاي مختلف هورمون هاي سيتوكينين بر ريز ازديادي گل آهار ظريف ( Zinnia elegans thumbelina) در شيشه (in verto )

Effect of different concentrations of Cytokinins on micropropagation of Zinnia elegans in vitro condition

For striding of the effects of plant growth regulators on in vitro culture of Zinnia elegans, an experiment has been done by using different concentrations of Cytokinins (benzyl amino purin and kinetin) (1,2,3 mM) in Murashig - skoog (MS) culture medium by factoryel manner. The applied explants were embryos with halfed dicotiledons, in which, the percentage of their geminating (seeding), number and length of their leaves, length of shoots and roots were considered. The majority number of leaves were seen in BAP hormone in concentration of 3 mM. The best concentration for increasing the length of leaves was observed in BAP hormone in concentration of 2 mM. The branch formation was also seen in BAP hormone in 2 mM concentration. The most increase of stem length was related to BAP hormone in 1 mM concentration and the most increase of root length was related to Khn hormone in concentration of 1 mM.
