Micropropagation of Dalbergia nigra, an endangered Brazilian forest tree [PDF]

open access: yesRevista Agrogeoambiental, 2021
We report in this work an in vitro propagation method for Dalbergia nigra using nodal segments from germinated seeds in vitro. Plant material was cultivated on MS medium supplemented with 6-benzyladeninepurine (BAP: 0 μM, 1.11 μM and 2.22 μM) and Naphthaleneacetic acd (NAA: 0.27 μM), combined with different amounts of subcultures for induction of shoot
