【 摘 要 】

Apical, cotiledonary, and hypocotiledonary explants and in vitro regenerated shoots of Capsicum annuum cv. Agronômico 10 were grown in (MURASHIGE & SKOOG, 1962)-MS médium, suppiemented with different concentrations and combinations of BAP, Adenine and Thidiazuron. According to the explant type and growth regulators used different in vitro morphogenetic responses were attained. Generally, culture media having high concentrations of BAP and Thidiazuron promoted induction and yield of calli from seedling explants but rhizogenesis was favored only under low concentrations of BAP. Multiple axilary buds were formed only when the explant in vitro regenerated shoots. BAP at 26.64 and 39.96µM maximized proliferation in 2.08 and 2.23 shoots per explant, respectively.
