In vitro propagation ofMimosa tenuiflora (Willd.) Poiret, a Mexican medicinal tree

Mimosa tenuiflora (Willd.) Poiret (Leguminosae) was micropropagated throughin vitro culture of axillary buds on Murashige and Skoog (MS) medium. Shoot formation was achieved when the media were supplemented with 0.1 mg.L(-1) IAA + 3 mg.L(-1) KN.In vitro rooting of regenerated shoots was achieved when 0.1 mg.L(-1) KN was combined with 1 mg.L(-1) IBA in the absence of IAA. Ninety-four percent of the rooted plants were succesfully adapted to field conditions and grown in the soil. A total of 180 trees grown under these conditions were obtained over a one-year period.
