Concentrações de sais em meios de cultivo para o desenvolvimento de barueiro in vitro

The objective of this work was to evaluate the effect of salt concentrations in culture media on the early development of “barueiro” (Dipteryx alata) seedlings, obtained from the shoot apex, in vitro. Two different in vitro culture media – Murashige u0026 Skoog (MS) and wood plant medium (WPM) – in different salt concentrations (25, 50, 75, and 100%) were used. At 120 days, the D. alata seedlings in the MS medium, in its original concentration (100%), developed better than in other concentrations or in the WPM. Therefore, the MS medium was considered the most suitable for ensuring in vitro establishment because it provided greater root length (27.65 cm) and number of leaves per plant (26 leaves) than the other medium.
