| ABSTRACT Potato cultivation is widespread around the world, being exposed to several abiotic stresses, including soils with high aluminum (Al) availability. Silicon (Si) is recognized for alleviating the stress caused by Al in various plant species. Thus, the aim of this study was to investigate the potential of Si to mitigate the oxidative stress caused by Al in potato genotypes, exhibiting differential sensitivity toward this element. Plants of the Al-sensitive genotype (SMIJ319-7) and Al-tolerant genotype (SMIF212-3) were grown for two weeks in a hydroponic system with the nutrient solution containing combinations of Al (0 and 1.85 mM) and Si (0, 0.5 and 1.0 mM). At the end of the experiment, photosynthetic parameters, pigment content, root and shoot... |

| Abstract The substrate used in seedling production plays a major role in the initial plant development. In this sense, the objective was to evaluate the emergence capacity and establishment of basil seedlings in different proportions of alternative substrates based on charred rice husk and commercial substrate S10®. The experiment was carried out in expanded polyethylene trays, using basil seeds (Horticeres seeds®), which lasted 28 days. The experimental design was completely randomized, with five treatments (T1: 100 % commercial substrate (BCS); T2: 80 % BCS + 20 % Charred rice husk (CRH); T3: 60 % BCS + 40 % CRH; T4: 40 % BCS + 60 % CRH; T5: 20 % BCS + 80 % CRH) and three repetitions. Were evaluated leaf number, shoot length, root length, root dry mass,... |

| 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... |
