Abstract In recent year Alstroemeria has gained a lot of interest as a cut flower Important reasons are diversity of color and flower shape easy cultivation low energy requirement and long vase life In the other hand its value as bedding or pot plant is not covered to every one Alstroemeria is propagated asexually trough rhizome division with low multiplication rate about five rhizome a year and contributes to the spread of viral diseases For these reasons and heterozygosity of Alstroemeria plants use of micro propagation techniques for Alstroemeria propagation in higher amounts seems to be necessary Direct organogenesis and plant propagation trough callus are desirable models for plant regeneration In this study appropriate conditions were obtained for callus induction from halved ovary and direct organogenesis from immature LQIORUHVFHQW K SRFRW OH DQG UKL RPH V EXG Rr callus induction halved ovaries were culture on both solidified and liquid MS medium contained various concentrations of mgl BA Best callus regeneration was done on D and NAA in combination with mgl D and mgl BA For plant liquid MS medium supplemented with regeneration from this newly produced callus different concentrations of BA were evaluated but plants were produced in none of the medium For direct organogenesis different parts of Alstroemeria plant were cultured on MS medium contained various mgl NAA In immature concentrations of BA and KIN in combination with inflorescent higher shoot induction rate shoots per explants was observed in mgl BA and mgl KIN and highest rooting medium supplemented with percent was done in medium supplemented with mgl BA and mgl KIN Addition of NAA had no effect on rooting of these explants and rooting was done in the same media which were used for shoot induction after subculture regimes In hypocotyle culture highest number of produced shoots was observed in medium contained mgl BA and mgl NAA and addition of BA had decreasing effect on multiplication rate from this parts After transition of explants with shoots rooting media highest number of explants with root and longest produced roots were observed in media supplemented with and mgl NAA in combination with mgl BA UHVSHFWLYHO Q WKH FDVH RI UKL RPH V EXG highest number of induced explants was observed in media contained mgl BA and mgl NAA Addition of BA caused decreasing of shoot length Highest number of produced rhizome was done from FXOWXUH RI UKL RPH V EXG LQ PHGLD VXSSOHPHQWHG ZLWK mgl BA Karyotype analysis of Alstroemeria ligto hybrid showed that this specious is diploid and contained chromosomes n x karyotypic formula for haploid set was m sm st and chromosomes number chromosome number and chromosome number were meta centric sub telo centric and sub meta centric respectively pdfMachine is a pdf writer that produces quality PDF files with ease Get yours now Thank you very much I can use Acrobat Distiller or the Acrobat PDFWriter but I consider your product a lot easier to use and much preferable to Adobe s A Sarras USA
