Resumo: | The use of substrates using or biochar as a component is a viable alternative in the production of forest seedlings, due to improvements in physical-chemical characteristics. In view of the above, the objective of this study was to evaluate the effect of particle size and the proportion of biochar bark from cariacar brasiliense on the production of Eucalyptus urophylla seedlings. The biochar was used in four particle sizes (> 0.5; 0.5-1.0; 1.0-2.0; 2.0-4.0 mm), mixed with the commercial substrate @bioplant (Sphagnum peat, coconut fiber, rice husks, pine husks and vermiculite) in five proportions: 0, 25, 50, 75%, 100% (v / v). Biodegradable as physical properties, particle density, bulk density and porosity of the tested substrates. The physiological development of the changes, on the other hand, was analyzed using the variables: germination percentage, emergence speed index, height, neck diameter, height / neck diameter ratio, articulated root length, dry root mass and dry mass for 120 days, correlating with the technical and chemical characteristics of the biochar used. The addition of biochar in smaller proportions (<25%) to the commercial substrate, gives the substrate improvements in the physical-chemical attributes, such as the increase in porosity. We conclude that the best physiological results for the species under study were used using biochar grain sizes between 1 and 4 mm regardless of the proportion and applied biochar. |

Diante do exposto, o objetivo deste trabalho foi avaliar o efeito do tamanho de partícula e da proporção de biochar de casca de Caryocar brasiliensis sobre a produção de mudas de Eucalyptus urophylla. O biochar foi empregado em quatro granulometrias (>0,5; 0,5-1,0; 1,0-2,0; 2,0-4,0 mm), misturados ao substrato comercial @bioplant (turfa de Sphagnum, fibra de Coco, casca de arroz, casca de pinus e vermiculita) em cinco proporções: 0, 25, 50, 75%, 100% (v/v). Avaliou-se as propriedades físicas, densidade de partícula, densidade aparente e porosidade dos substratos testados. Já o desenvolvimento fisiológico da muda foi analisado através das variáveis: porcentagem de germinação, índice de velocidade de emergência, altura, diâmetro de colo, relação altura / diâmetro de colo, comprimento de raiz pivotante, massa seca da raiz e massa seca aérea aos 120 dias, correlacionando com as características físicas e químicas do biochar utilizado. A adição do biochar em menores proporções (< 25%) com o substrato comercial, confere ao substrato melhorias nos atributos físico-químicos, como o aumento da porosidade. Conclui-se que os melhores resultados fisiológicos para a espécie em estudo foram obtidos utilizando granulometrias de biochar entre 1 e 4 mm independente da proporção e biochar aplicada.
