Selection of maize hybrids for tolerance to aluminum in minimal solution
The aim of this study was to determine the Al concentration and the period of exposure of the roots of maize hybrids in minimal solution for efficient selection of genotypes that are Al-tolerant. Two experiments were performed (48 and 96 h of exposure) with increasing doses of Al in minimal solution; the block design was completely randomized in a split-plot design with 3 replications.
