\begin{abstract}
\normalsize{
African violet (Saintpaulia ionantha Wendl.) is one of the plants which its micropropagation by tissue culture method has been done in commercial scale, but unfortunately in our country its micropropagation is being carried out using classical methods such as leaf cuttings. For production of one thousands African violet (Saintpaulia ionantha Wendl.) cuttings by classical method, 667 full"=grown plants are needed, while by using tissue culture technique, only 3 full"=grown plants will be necessary.  This study was designed using GB (Grapevine Bleeding) for economical purposes of tissue culture technique in micropropagation of African violet. In this study the GB used as growing medium \textit{in~vitro}.  Three different growing media including \mbox{100\,\%} MS, \mbox{100\,\%} GB and \mbox{50\,\%}  MS+\mbox{50\,\%} GB as well as three kinds of explants (leaf, stem, node) used for regeneration. Several parameters such as shoot numbers per explant, shoot length (cm) and shoot regeneration percentage were measured in each regenerated plant. Results showed that the best economic growing medium was \mbox{50\,\%} MS+\mbox{50\,\%} GB with leaf as explant. The selected explant was cultured in selected suitable medium with different amounts of growth regulators including BAP and NAA. The highest numbers of shoot, shoot length and shoot regeneration percentage were observed in \unitfrac[0.5]{mg}{L} BAP+\unitfrac[0.7]{mg}{L} NAA. In other study the different amounts of other growth regulators including BAP and IBA used for root generation and results showed that the highest number of roots, root length and rooting percentage were obtained in \unitfrac[0.5]{mg}{L} BAP+\unitfrac[0.5]{mg}{L} IBA.}
