A study was conducted to evaluate the effect of phytohormone BAP alone and in combination with IBA or NAA for invitro propagation of Jatropha curcas 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 μM BAP or 13.32 and 4.92 μM of BAP and IBA respectively. Similarly, maximum shoot buds per explant (6.7) and shoot length (4.5 cm) were obtained when 13.32 μM BAP and 4.92μM IBA was added to the MS medium. Shoots produced were re-cultured to MS, ½ MS media and ½ MS medium supplemented with different concentrations of IBA and were studied for rooting, where the response was highly significant. IBA supplemented to ½ MS medium at 14.76μM gave maximum (4.93) roots per culture.

    A plantlet regeneration protocol was developed for Pinus ayacahuite var. ayacahuite (Ehrenb.). Embryos from mature seeds from ten provenances were cultured in a 16-h photoperiod for 3 days on a medium containing 30 mM sucrose and 0.7% agar. Cotyledons from these embryos were subcultured onto MCM...
