Abstract :
    ABSTRACT: Due to the sensitivity of potato to virus, production of virus-free plants, reduction in production costs and increased performance, in vitro cultivation of this plant is very important. To evaluate the effect of 11 combined hormones and vitamins as treatments on main and secondary shoot length, the minimum and maximum of secondary shoot length and number of secondary shoot Agria potatoes, an experiment was conducted in 2014-2015 in a completely randomized design with three replications in laboratory condition. The result of variance analysis showed that between the hormonal compounds from the point of evaluated traits there is significant difference at 1% probability and this suggests that different hormone combinations with different concentrations have significant effects on the traits that were assessed. Based on the table comparison treatments, cytokinin compounds (PBA) in various concentrations reduced secondary shoot length and conversely, biotin, thiamin and pyroxene compounds in measured concentrations increased secondary shoot length. This can also be seen in minimum and maximum secondary shoot length. Treatment compounds of B5 ،B10 and P20 cause increase and PBA3 and PBA4 compounds cause reduction in main shoot length. Based on the results obtained, cytokinin compounds in evaluated concentrations increased the number of secondary shoot.
