-This investigation aimed at studying the germination and initial growth of Alatiglossum fuscopetalum (Hoehne) Baptista under in vitro conditions. The eff ects of Murashige/Skoog (MS and ½MS), Knudson (KN), and Vacin/Went (VW) culture media on the in vitro germination of A. fuscopetalum were analyzed. The infl uence of these media on the multiplication and initial growth of 90-day-old seedlings, and of diff erent sucrose, benzyladenine [BA] and indole-butyric acid [AIB] concentrations on the multiplication and growth of 120-day-old plants were also evaluated. The results revealed that ½MS was the most appropriate medium for germination. Regarding the growth of 90-day-old seedlings, MS provided the best outcome. The most eff ective medium for the multiplication and growth of 120-day-old plants was ½MS. Sucrose ranging from 1% to 3% favored plant growth. BA at 1 mg L -1 and IBA at 2 mg L -1 were the best growth regulator treatments for shoot proliferation and root growth, respectively.
