Abstract

ARARUNA, Elequisandra da Costa et al. Salt concentrations in culture media for the development of Dipteryx alata in vitro. Pesq. agropec. bras. [online]. 2017, vol.52, n.12, pp.1295-1300. ISSN 0100-204X.  https://doi.org/10.1590/s0100-204x2017001200020.

The objective of this work was to evaluate how salt concentrations in media used for in vitro cultures affect the early development of “barueiro” (Dipteryx alata) seedlings obtained from the shoot apex. Two different in vitro culture media - Murashige & 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.
