Abstract

Direct differentiation of shoot buds from hypocotyl segments of 12-d-old seedlings of Tamarindus indica was obtained on Murashige and Skoog (MS) medium with or without growth regulators. The highest regeneration (66 %) and the maximum number of shoots (3 - 4) per explant were obtained from the explants on MS medium containing 6-benzylaminopurine (5 × 10-6 M). A maximum roots per shoot were produced on medium containing 3-indole butyric acid (5 × 10-6 M). The resulting plantlets were hardened and transferred to soil in pots where 75 % of them survived and resumed growth. Histological examination of explants suggests that the shoots were of de novo origin which would make this system suitable for transformation experiments.
