Effects of naphthaleneacetic acid and 6-benzylaminopurine on In vitro buds proliferation of Stryphnodendron adstringens (Mart.) Coville

Abstract

- The aim of the present work was to evaluate the effects of BAP and NAA concentrations on plant micropropagation of Stryphnodendron adstringens (Mart.) Coville. Axilary buds excised from plantlet maintained in vitro were cultivated on «MS» medium combined with 6-benzylaminopurine-BA (0.0, 0.5, 1.0, 2.0 and 4.0 mg/l) and naphthaleneacetic acid (NAA) (0.0, 0.1 e 1.0 mg/l) in a completely randomized design with four replications. The best proliferation of buds happened at BAP 4.0 mg/l and NAA absence. In the absence of growth regulators the highest number of large sprouts (1.0 cm) was observed.
