Rahman Journal of Animal and Plant Sciences JAPS 20142014/02/01 24 1 229-233 1018-7081 NA <p>A study was conducted to evaluate the effect of phytohormone BAP alone and in combination with IBA or NAA for in-vitro propagation of&nbsp;<em>Jatropha curcas</em> shoot tip explants. MS medium supplemented with various concentrations of phytohormones significantly affected shoot induction. Maximum (93.33%) shoot induction occurred when MS medium was supplemented with 8.88 &micro;M BAP or 13.32 and 4.92 &micro;M of BAP and IBA respectively. Similarly, maximum shoot buds per explant (6.7) and shoot length (4.5 cm) were obtained when 13.32 &micro;M BAP and 4.92&micro;M IBA was added to the MS medium. Shoots produced were re-cultured to MS, &frac12; MS media and &frac12; MS medium supplemented with different concentrations of IBA and were studied for rooting, where the response was highly significant. IBA supplemented to &frac12; MS medium at 14.76&micro;M gave maximum (4.93) roots per culture.</p> Jatropha curcas,micropropagation, phytohormones, BAP, IBA Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2014-JAPS-34
