| Aluminum (Al) toxicity is a limiting factor for crop production in acid soils, which cover approximately 60% of the Brazilian territory. This study aimed to evaluate the effects of Al on growth and tissue Al concentration of two Pfaffia glomerata accessions (BRA and JB/UFSM). Plantlets were grown in a hydroponic system with five Al concentrations (0, 50, 100, 150 and 200mg L-1) for 7 days. Most of the evaluated parameters presented significant interaction between both P. glomerata accessions and Al levels in nutrient solution and, in general, Al treatments negatively affected plant growth, especially roots. Moreover, BRA accession showed higher Al accumulation in its tissues than JB/UFSM and, consequently in BRA accession the growth was impaired... |

| ABSTRACT: Aluminum (Al) is highly toxic to plants, causing stress and inhibiting growth and silicon (Si) is considered beneficial for plants. This chemical element has a high affinity with Al. The aim of this study was to investigate the potential of Si to mitigate the toxic effects of Al on potato ( Solanum tuberosum L.) plants and assess whether this behavior is different among genotypes with differing degrees of sensitivity to Al. Potato plants of the genotypes SMIJ319-7 (Al-sensitive) and SMIF212-3 (Al-tolerant) were grown for fourteen days in nutrient solution (without P and pH 4.5±0.1) under exposure to combinations of Al (0 and 1.85mM) and Si (0, 0.5 and 1.0mM). After this period, shoot and roots of the two genotypes were collected to determine Al... |
