The use of residues from coffee production to obtain biochar is a sustainable approach, which aims to minimize the environmental impact of these materials. In this study, the effect of adding coffee straw biochar on the physiological quality of lettuce and sorghum seeds was investigated. Thus, the objective of this work was to study the effect of adding different concentrations of coffee biochar in the substrate composition on the physiological quality of lettuce (Lactuca sativa) and sorghum (Sorghum bicolor) seeds. The experimental design used was completely randomized, with five concentrations of biochar (0; 7.5; 15; 30 and 60%), conducted with four replications of 25 seeds. The use of biochar in the concentrations studied does not provide an increase in the average germination percentage and vigor of lettuce and sorghum seeds. The increase in the concentration of biochar caused less seed vigor, suggesting a toxic effect. For seed germination, there was no significant difference between lettuce and sorghum species, regardless of treatment. For the germination speed index, sorghum seeds have higher means, except for the treatment with the addition of 15% coffee straw biochar. Lettuce seeds have higher shoot length averages, except for treatment with 100% commercial substrate. The sorghum seeds have higher mean root length and dry mass than lettuce, regardless of the treatment.

Assim, o objetivo deste trabalho foi estudar o efeito da adição de diferentes concentrações de biocarvão de café na composição do substrato sobre a qualidade fisiológica de sementes de alface (Lactuca sativa) e sorgo (Sorghum bicolor). As variáveis analisadas foram: teor de água das sementes, porcentagem de germinação, Ãndice de velocidade de germinação, comprimento da parte aérea, comprimento da raiz e massa seca das plântulas. O delineamento experimental utilizado foi inteiramente casualizado, com cinco concentrações de biocarvão (0; 7,5; 15; 30 e 60%), conduzido com quatro repetições de 25 sementes. A utilização do biocarvão nas concentrações estudadas não proporciona aumento na porcentagem de germinação e no vigor das sementes de alface e sorgo. O aumento da concentração de biocarvão causou menor vigor das sementes, sugerindo efeito tóxico. Para germinação de sementes, não houve diferença significativa entre as espécies de alface e sorgo, independente do tratamento. Para o Ãndice de velocidade de germinação, as sementes de sorgo apresentam maiores médias, excetuando-se para o tratamento com adição de 15% de biocarvão de palha de café. As sementes de alface apresentam maiores médias de comprimento de parte aérea, excetuando-se para o tratamento com 100% de substrato comercial. As sementes de sorgo apresentammédias de comprimento de raiz e massa seca superiores à s de alface, independentemente do tratamento.

Fusariosis, caused by the fungus Fusarium subglutinans f. sp. ananas (Syn. F. guttiforme), is one of the main phytosanitary threats to pineapple (Ananas comosus var. comosus). Identification of plant cell responses to pathogens is important in understanding the plant?pathogen relationship and establishing strategies to improve and select resistant cultivars. Studies of the structural properties and phenolic content of cell walls in resistant (Vitoria) and susceptible (Perola) pineapple cultivars, related to resistance to the fungus, were performed. The non-chlorophyll base of physiologically mature leaves was inoculated with a conidia suspension. Analyses were performed post-inoculation by light, atomic force, scanning and transmission electron microscopy, and measurement of cell wall-bound phenolic compounds. Non-inoculated leaves were used as controls to define the constitutive tissue characteristics. Analyses indicated that morphological differences, such as cell wall thickness, cicatrization process and lignification, were related to resistance to the pathogen. Atomic force microscopy indicated a considerable difference in the mechanical properties of the resistant and susceptible cultivars, with more structural integrity, associated with higher levels of cell wall-bound phenolics, found in the resistant cultivar. p-Coumaric and ferulic acids were shown to be the major phenolics bound to the cell walls and were found in higher amounts in the resistant cultivar. Leaves of the resistant cultivar had reduced fungal penetration and a faster and more effective cicatrization response compared to the susceptible cultivar.
