-This study aimed to evaluate the effect of substrate on growth, emergence, nutrition, and quality of Anacardium othonianum Rizz. (cerrado cashew tree) seedlings. The experiment was conducted in a greenhouse at the Plant Tissue Culture Laboratory on the Rio Verde campus. The following substrates were used: 1) Bioplant ® , 2) Mecplant ® (MP) + carbonized rice husk (CRH) (7:3), 3) fine-grained vermiculite (FGV), 4) FGV+CRH (3:1), 5) FGV+CRH (1:1), 6) FGV+CRH (1:3), and 7) sugarcane bagasse (SB) + sugarcane mill filter cake (FC) (3:2). Emerged seedlings were counted at 2-day intervals for 38 days following emergence of the first seedling. At 39, 64, and 89 days after seeding (DAS), the following variables were measured: stem length (SL), stem diameter (SD), and number of leaves (NL). Accumulated dry weight, quality indices, and leaf macro-and micronutrient levels were determined at 89 DAS. Plants grown in the FGV and FGV+CFH (1:3) substrates had shorter stem lengths than the plants grown in other substrates. Increases in seedling growth were smaller between 64 and 89 DAS compared to the initial period of the experiment. The highest leaf N concentrations were found in the SB+FC substrate treatment group; P and K concentrations were higher for the MP+CRH (7:3), SB+FC, and Bioplant ® treatments; and Ca levels were higher for the SB+FC and MP+CRH (7:3) substrate treatments. The MP+CRH (7:3) substrate treatment group had the highest leaf B and Mn micronutrient concentrations, and plants from the Bioplant ® substrate group had the highest leaf B micronutrient content. Mg, S, Cu, Zn, and Fe concentrations did not differ among the different substrates. The plant traits that differed most among the treatments included stem length for the FGV and FGV+CRH (1:3) substrate groups and leaf nutrient concentrations, which were higher for the SB+FC group followed by the MP+CRH and Bioplant ® treatments.

“…Há diversas pesquisas científicas que caracterizam fisicamente tipos de substratos (Cardoso et al, 2010;Fermino e Kämpf, 2006;Pagliarini et al, 2012;Valero et al, 2009;Vieira e Pauletto, 2009), avaliam a utilização de novos materiais como substratos (Daudt et al, 2007;Fermino et al, 2010) ou os estudam com o desenvolvimento de diversas culturas (Fernandes et al, 2006(Fernandes et al, , 2007Souza Júnior et al, 2011). Entretanto, com relação à avaliação e comparação dos métodos foram poucos os trabalhos encontrados (Abreu et al, 2012;Baumgarten, 2002; Fermino e Kämpf, 2012; Terés et al, 2001; Wever e van Winkel, 2004).…”

A caracterização física de substratos para plantas no Brasil ainda é incipiente, embora, apenas com a definição adequada de métodos confiáveis seja possível padronizar insumos e fornecer as recomendações necessárias aos produtores. Objetivou-se caracterizar fisicamente seis substratos para plantas e comparar métodos prescritos pelo Ministério da Agricultura, Pecuária e Abastecimento brasileiro e pelo Comitê Europeu de Normatização. Os substratos avaliados foram: fibra de coco granulada, dois tipos de casca de pínus, casca de arroz estabilizada e duas misturas (50:50, v:v), uma de casca de arroz com fibra de coco granulada e a segunda de casca de pínus e casca de arroz. O projeto, realizado em 2009, teve delineamento experimental inteiramente casualizado. Os substratos apresentaram diferenças quanto aos atributos físicos: umidade, granulometria, densidade volumétrica, capacidade de retenção de água, densidade de partícula e porosidade, características com as quais se pode inferir sobre sua utilização. Quanto aos parâmetros físicos recomendados em cada um dos métodos, sugere-se: para determinação da umidade da amostra, secagem à temperatura de 65 ± 5 °C; para granulometria, tempo de 10 min de agitação das peneiras; para densidade volumétrica, método da autocompactação; para capacidade de retenção de água, a base do anel volumétrico da amostra como referência e a adoção da dupla saturação e da pré-tensão em 50 hPa; para determinar a curva de retenção de água dos substratos, os pontos de tensão em 10, 30, 50 e 100 hPa; para caracterização dos substratos quanto à sua origem, inclusão da densidade de partícula pela determinação da matéria orgânica e de cinzas.Palavras-chave: fibra de coco, casca de arroz, casca de pínus, densidade volumétrica, porosidade, capacidade de retenção de água. Physical characterization of substrates for plants AbstractPhysical characterization of substrates in Brazil is still incipient and, only with the proper definition of reliable methods, substrates can be standard izedand recommendations can be provided for the producer. The objective was to physically characterize six types of substrates for plants and to compare the methods prescribed by Ministry of Agriculture, Livestock and Supply and by European Committee for Standardization. The six substrates evaluated were: granulated coconut fiber, two types of pinus bark, stabilized rice rusk and two mixtures (50:50, v:v), one of rice rusk with granulated coconut fiber and the second pinus bark with rice husk. The project, realized in 2009, has a completely randomized experimental design. The substrates showed differences as to the physical attributes studied: humidity, particle size distribution, bulk density, water retention capacity, particle density and porosity, characteristics with which one can infer on their use. For the physical parameters for each of the recommended methods are suggested: for the determination of the sample humidity, drying at 65 °C ± 5 °C; for particle size distribution, time of 10 minutes of stirring sieves; for th...

“…According to these criteria, DD and MD values of substrates used in the present study are below those considered suitable (Table 2). Low-density substrates are more suitable for use in trays (FERMINO et al, 2010;KÄMPF, 2000). Trimix ® substrate presented the highest amount of available water (AW) between 1 and 10 kPa, followed by FV+RH (3:1) (Table 2).…”

Physiology and quality of Eugenia dysenterica DC seedlings grown in vermiculite and rice husk-based substrates

et al. 2018

Eugenia dysenterica DC is a fruiting species endemic to the Brazilian Cerrado, belonging to the Myrtaceae family and popularly known as Cagaiteira. It has medicinal and antifungal properties, and has an important function in the ecosystem. Nevertheless, there are few studies about the maintenance of this species. The aim of this study was to evaluate the growth, nutrition, quality and physiology of E. dysenterica seedlings grown in fine vermiculite and rice husk-based substrates in the following combinations: 1:0, 3:1, 1:1, and 1:3, in addition to Trimix® commercial substrate and vermiculite only. The physical attributes of substrates (dry and moist densities, available water, remaining water, aeration space and total porosity), seedling emergence percentage, emergence speed index, gas exchange, chlorophyll a fluorescence, relative seedling water content, relative substrate moisture content, plant biometric growth characteristics, accumulated dry weight and nutritional status were evaluated through leaf macronutrient content 128 days after emergence. The increase in the proportion of rice husk mixed with vermiculite resulted in reduction of the dry and moist densities of substrates, available water, remaining water, total porosity and moisture content, and increased the aeration space in substrates. The fine vermiculite substrate promoted the highest Dickson’s quality index and the greatest stem diameter of plants. Seedlings grown on vermiculite substrate presented higher N and K content in leaves, and those grown in Trimix® substrate showed higher leaf Mg content. Substrates did not alter the physiological attributes of seedlings.
