Selection of maize hybrids for tolerance to aluminum in minimal solution

C. J. Coelho, Molin, D., Joris, H. A. Wood, Caires, E. F., Gardingo, J. R., and Matiello, R. R., Selection of maize hybrids for tolerance to aluminum in minimal solution, vol. 14, pp. 134-144, 2015.

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.

Genetic variability of NaCl tolerance in tomato

Cultivation of crops in soils with high salt (NaCl) content can affect plant development. We examined the morphological and physiological mechanisms of salt tolerance in tomato. The responses of 72 accessions of tomato (Solanum lycopersicum) to salinity were compared by measuring shoot and root lengths, and fresh shoot and root weights relative to those of controls (plants grown in normal salt levels). All traits were reduced at the seedling stage when salinity levels were increased. The accession x salinity interaction was significant for all traits.
