“…There is a disparity regarding the P and Ca content of the two substrates, as CB substrate has higher P and Ca contents. Both elements play important roles in root growth and development (Silva et al, 2017). We can conclude that CB substrate provided superior results by combining good aeration and better nutrient Ca and P contents.…”

“…The CB substrate has a lower water retention capacity, so a higher irrigation level is necessary to meet the water needs of the seedlings and to ensure greater LA, expanding the photosynthetic capacity, which implies faster growth rates (Silva et al, 2017). The maximum pot capacity (water retention) referring to CB substrate was 57.53 mL of water, on the other hand, a higher value was observed for the substrate with the same residue mixed with carbonized rice husks, 172.20 mL.…”

A rosa do deserto tem ganhado notoriedade no mercado ornamental de flores por ser plantas belíssimas e de fácil manejo, entretanto, ainda são poucas as informações sobre o cultivo da espécie. Tendo em vista essa problemática, objetivou-se avaliar substratos formulados a base de bagana de carnaúba (Copernicia prunifera Mill.), casca de arroz carbonizada (Oryza sativa L.), caule decomposto de babaçu (Attalea speciosa) e solo, com diferentes profundidades de semeadura, tipos de sombreamento e lâminas de irrigaçãoara produção de mudas de Adenium obesum . Foram adotados delineamento inteiramente casualizado em esquema fatorial 4x3. Como variáveis avaliadas: germinação, índice de velocidade de emergência, altura da planta, altura do caudex, número de folhas, diâmetro do caule, diâmetro do caudex, comprimento radicular, massa seca e fresca das partes aéreas e raiz, volume da raiz e índice de qualidade de Dickson. Mediante os resultados as mudas se desenvolveram melhor sob profundidade de semeadura de 10 mm e substrato com 100% a.C. Como telas de sombreamento não influenciam no desenvolvimento, recomendando o uso do ambiente a céu aberto. E ainda utilizando o mesmo substrato é indicado lâminas entre 50 e 75% da capacidade de vaso, já para os substratos demais, recomenda-se a lâmina de 25%.

“…Among the factors that influence root formation in cuttings, is the substrate and the genetic potential for rooting (Fachinello et al, 1995). The growing substrate implies a preponderant factor in the development and greater vigor of seedlings, especially, when it incorporates physical and chemical characteristics suitable for production (Silva et al, 2017;Marques et al, 2019).…”

Guarana [Paullinia cupana var. sorbilis (Mart.) Ducke] is a species of great economic and social important in Brazil, as it is the only commercial guarana producer in the world. The vegetative propagation method indicated for the culture is stem cuttings, which aims at productivity, tolerance, and uniformity of clonal cultivars, because reproduction by seeds has slow germination and high genetic variability, which in traditional varieties is an undesirable factor. Genetic factors can interfere with the rooting capacity of the crop. Studies seek alternatives that can improve this condition and enhance the production system. Use of growth regulators, microorganisms that promote plant growth, variation of substrates and fertilization, have been strategies used. Preliminary tests on the rate of stem rooting and seed germination with the use of exogenous phytohormone did not demonstrate in relation to the non-application of these inducers. The use of rhizobacteria, which presents itself as a promising activity in many cultures, has not yet been demonstrated in the culture of guarana. On the other hand, the influence of different substrates on rooting has already shown consistent results as a function of rooting rate. Fertilizing the mother plants as recommended by the production system for the crop has proven to be an efficient procedure. There are still few studies aimed at improving the spread of guarana, demonstrating that new protocols need to be explored, or that the protocols already used are reviewed from another perspective.
