Resumo
This research work was carried to verify the effects of salt concentrations with iron, copper and zinc of the MS
(MURASHIGE & SKOOG, 1962) medium on explants oxidation control for banana plants, cv. Prata (Musa AAB). Three salt
concentrations (100, 50, 0 μM) of FeEDTA and two concentrations (100, 0 μM) of (CuSO4). 5H2O and two concentration (30 e 0 μM)
of (ZnSO4). 7H2O were utilized. Completely randomized in a 3x2x2 factorial scheme with fifteen repetitions were utilized. Shoot tip
apices were inoculated in MS medium. Explants fresh matter weight, height and oxidation grade were evaluated 28 days after inoculation.
It was observed that iron, copper and zinc are essential to explants growth. Iron concentration reduction caused decrease in oxidation
grade, the reduction or elimination of iron, copper and zinc in MS medium, isolated or in combination forms was not sufficient to
eliminate the oxidation grade.
