“…As main chemical characteristics, the SS presents levels of N, P, K, Ca, Mg, Na, Cu, Fe, Mn, and Zn, for example, which act in cellular composition, enzyme and protein synthesis, perform structural function, and are involved in virtually all processes of plant growth and reproduction (GONDIM et al, 2019;KLAFE et al, 2022). The available values of these nutrients in SS vary, as does the demand of each forest species, but both macro and micronutrients are vital for developing quality seedlings (BANDEIRA et al, 2018). It is important to note that in plant tissues, the absorption process occurs by the root directly arranged in the substrate, and that by active or passive transport, they will be distributed internally in tissues according to the plant's needs (TRAZZI et al, 2013).…”

The substrate has great importance for the development of seedlings, and many materials can be used for its composition. Thus, the aim of this study was to evaluate the quality of Jacaranda mimosifolia D. Don seedlings on different substrates with sewage sludge (SS). The substrates were combined as follows: T1 (50% commercial substrate Plantmax® + 50% organic compost from horse bedding (organic compost -OC); T2 (20% SS + 80% OC); T3 (40% SS + 60% OC); T4 (60% SS + 40% OC). At 180 days after sowing, the following biometric characteristics were measured: aerial part height and root system length; stem diameter; number of leaves; fresh and dry mass of the aerial part and root; and total mass. The Dickson Quality Index (DQI) was calculated, and the content of macro and micronutrients in the root and aerial parts was quantified. The accumulation of macronutrients in the root system was in the order K>N>Mg>P>Ca>S and in the aerial part, N>Ca>K>P>Mg>S. Sulfur was less concentrated in the two vegetative structures. For the micronutrients, the accumulation in the root system was in the order Fe>Mn>Zn>Cu>B, and in the aerial part, it was Fe>Mn>Zn>B>Cu. In general, the Fe and Mn content were more concentrated in the two vegetative structures studied. The recommended substrate formulated according to our results was 60% SS + 40% OC, presenting the highest mean values of growth and biomass. Thus, the use of SS can be considered a viable substrate for the production of healthy seedlings of J. mimosifolia for planting in the field.

“…Assim o substrato é o fator que exerce influência significativa no crescimento das mudas florestais, sendo vários os materiais que podem ser usados na sua composição original ou combinados (CRUZ et al, 2006). Para escolha de um substrato, deve-se observar principalmente, seus aspectos físicos e químicos, a espécie a ser plantada e os aspectos econômicos, como baixo custo e grande disponibilidade (ASSENHEIMER, 2009;BANDEIRA et al, 2018).…”

“…Neste contexto, segundo Silva et al (2020) a pesquisa sobre o potencial uso de diferentes substratos tem ganhado importância significativa, pois os diferentes tipos de substratos são essenciais para o bom desenvolvimento da germinação das sementes e do crescimento das mudas. Também, além do tipo adequado de substrato, é salutar observar que as instalações para a produção de mudas florestais geralmente começam em um viveiro, pois o viveiro é uma área protegida onde as mudas são cultivadas em condições controladas, seja em relação ao ambiente, ou em relação a proteção contra ataques de doenças bióticas, pragas e plantas infestantes (BANDEIRA et al, 2018).…”

A produção de mudas de Jacaranda cuspidifolia em diferentes substratos é uma das formas de desenvolver mudas de espécies nativas que possam contribuir com a recuperação de áreas degradadas do bioma Cerrado. A pesquisa teve como objetivo analisar o crescimento e o desenvolvimento de mudas da espécie Jacaranda cuspidifolia sob diferentes substratos. A metodologia da pesquisa foi desenvolvida por meio da seleção de sementes vigorosas de uma matriz de Caroba-roxa (Jacaranda cuspidifolia) existente na arborização da Universidade Federal do Tocantins, em Gurupi. A partir de então foi realizado o beneficiamento das sementes, por 24 h. Para a realização da pesquisa foram utilizados quatro tipos de substratos, sendo: terra de barranco; substrato comercial; terra de barranco com esterco bovino curtido; e substrato comercial com terra de barraco. Desta forma, foram realizados os plantios, ou seja, o experimento ocorreu em quatro blocos de 25 mudas, totalizando 100 amostras. Aguardou-se a germinação por 15 dias, a partir de então, durante 7 semanas foram colhidos os dados sobre germinação e desenvolvimento. As variáveis analisadas foram a taxa de germinação (TG), altura das Mudas (H), diâmetro do caule (DC) e o números de folhas (NF). A pesquisa proporcionou uma análise das diferentes condições de germinação e desenvolvimento da espécie Jacaranda cuspidifolia em diferentes substratos, assim concluiu-se que existe maior eficácia na germinação e desenvolvimento das mudas por meio do Substrato Comercial e do Substrato Comercial misturado com Terra de Barranco, de acordo com as variáveis analisadas.

This study evaluated the initial growth and tolerance to water stress after planting Samanea saman seedlings produced with different substrates and inoculation patterns. The experiment used a factorial design (3 × 3), with three substrates: standard (67% subsoil + 33% cattle manure), a commercial substrate (composed mainly of peat), and treated sewage sludge; and three inoculation patterns: control (no inoculation), fertilized (no inoculation + chemical fertilization), and inoculation with nitrogen-fixing bacteria and arbuscular mycorrhizal fungi. The seedlings were planted in plastic pots inside a greenhouse. They received irrigation after planting and were submitted to water deficit for 35 days, followed by rehydration for 31 days. The inoculation promoted higher height and biomass for seedlings produced in the standard substrate. In the sludge, the roots biomass decreased when fertilized or inoculated. Seedlings grown in sludge showed higher height and biomass before planting and at the end of the experiment. Although, after rehydration, the height increment was similar for the sludge and the standard substrate. Seedlings grown with the commercial substrate are not recommended for planting sites subjected to water deficit. The standard substrate with inoculation and the sludge without inoculation or fertilization produced seedlings that showed better recovery and growth after water deficit.
