“…In addition to micronutrients, amino acids are essential to potentiate germinability. The application of amino acids through seed treatment can be connected to the processes of protein synthesis for embryo growth and, additionally, amino acids are precursors of other substances that regulate plant metabolism (DÖRR et al, 2020). Considering the specificities of each micronutrient or amino acid, they can be incorporated into the seeds and assist in seedling development, as observed by the higher seed seed germination speed, i.e., increases in the physiological potential as the biostimulant rate was increased (Figure 3B).…”

“…The application of micronutrients to castor bean seeds resulted in increases in seed germination and vigor (OLIVEIRA et al, 2010). Micronutrients applied through seed treatment also affected positively germination and vigor of green bean seeds (OHSE et al, 2014) and, application of amino acids resulted in better performance of seedlings, mainly under adverse conditions, for broccoli (BETTONI et al, 2013), wheat (HAMMAD; ALI, 2014), Eustoma grandiflorum (MONDAL et al, 2015), and soybean (DÖRR et al, 2020) crops.…”

Direct sowing is the most used watermelon propagation method in Brazil. Therefore, the use of treated seeds is an alternative for improving uniformity of plant stands at planting. Thus, the objective of this study was to assess the effects of seed treatments with biostimulant on the germination and vigor of watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai] seeds of the cultivar Crimson Sweet. A completely randomized experimental design with four replications was used. The seed treatments consisted of six biostimulant (Agressive Desperta®) rates (0, 1, 2, 3, 4, and 5 mL kg-1). Seed germination speed index, seedling length, seedling dry weight, seedling emergence in the field, and seedling emergence speed index were evaluated. The treatment of watermelon seeds with biostimulant resulted in increases in seed germination speed and seedling length and dry weight as the biostimulant rate was increased. Seedling percentage and emergence speed increased up to the rate of 3 mL kg-1 under field conditions; however, application of higher rates resulted in phytotoxicity.

“…É evidente a influência da pureza genética, da integridade física, da ausência de misturas com sementes de plantas invasoras, do potencial fisiológico e da sanidade sobre o desempenho das sementes e das plantas delas originadas (MARCOS FILHO, 2015). Segundo Dörr et al (2020), plantas de soja (Glycine max (L) Merrill). provenientes de sementes de elevada qualidade fisiológica produzem sementes de desempenho fisiológico superior, confirmando as informações destacadas por Marcos Filho (2015).…”

A utilização de sementes de elevada qualidade representa prática de manejo essencial para o estabelecimento e desempenho das culturas, sendo insumo fundamental para o desenvolvimento da agricultura. O uso de técnicas adequadas nos diversos sistemas de produção das culturas é fator fundamental para se obter maiores produtividades. Nesse sentido, cita-se que é crescente a utilização de novos produtos para incorporação de aditivos às sementes, objetivando melhorar seu potencial produtivo. No entanto, pouco se sabe sobre o real efeito desses produtos no desenvolvimento e produtividade agrícola e qualidade das sementes produzidas. Objetivou-se com o presente trabalho abordar os principais efeitos verificados no tratamento de sementes com produtos à base de fertilizantes e reguladores de crescimento. Destaca-se que os resultados verificados na literatura quanto à utilização de fertilizantes e reguladores de crescimento fornecidos via sementes já é uma realidade na agricultura e com resultados bem promissores. É importante destacar que as repostas à aplicação desses produtos dependem de uma série de fatores como espécie em estudo, composição das substâncias presentes nos produtos, das condições do ambiente e formas de aplicação, fatos estes que justificam mais estudos no setor.

The advancement and intensification of industrial and mining activities has generated a series of impacts on natural ecosystems, combined with the inappropriate use of agrochemicals and the erroneous disposal of electronic products, contributing to soil contamination with a diversity of chemical elements, including heavy metals. Due to this, this work aimed to evaluate the effect of increasing dosages of nickel on the anatomy, biochemistry and oxidative system of Brazilian mahogany (Swietenia macrophylla), a forest species from the Amazon, seeking to indicate the potential use of this species in phytoremediation programs. of soils contaminated with heavy metals. The seeds were grown under a constant temperature of 28°C, relative humidity (RH) of 90% with a 12-hour photoperiod for 43 days. The experimental design used was randomized blocks (DBC), with five treatments (0, 2, 4, 6 and 8 mg.L-1 of Nickel), with six replications. Data were subjected to analysis of variance (ANOVA) and means were tested for significant differences using the Tukey test at 5% significance. Changes in the anatomy of the different organs were observed, with differences in the cells in the central region of the leaf, the stem and the root. The concentration of total carbohydrates had no statistical differences with the application of nickel, however changes were observed in photosynthetic pigments, reducing sugars and sucrose as an adaptive form to nickel. The increase in nickel dosages was accompanied by the synthesis of ammonium, amino acids and proline in the root, while the synthesis of glycine was reduced. In the leaf, there was an increase in amino acids with an increase in metal, accompanied by a decrease in glycine. The plant antioxidant defense system was efficient in attenuating the toxic effects of ROS, with significant actions of CAT and SOD enzymes in the root, while the leaf had the main action of APX and CAT. The cultivation of mahogany plants can be advocated to mitigate Ni pollution in these areas, as this forest species has a particular characteristic of resistance to stressful conditions in contact with the heavy metal.
