Resumo: | Our goal was to evaluate the root development of flaxseed and its relationship with soil aggregation and organic carbon storage in two sowing seasons under soil conservationist management, in Santa Catarina state, Brazil. We used three flaxseed genotypes: Aguará and Caburé from Argentina, and Gold from Brazil, sowings in April and May in a no-tillage system under Haplumbrept. In the flowering stage, the root system was evaluated by image analyze using a Safira software. Root distribution maps were used by geostatistical kriging. At the harvest stage, soil blocks were sampled for analyze the aggregates morphometry by image with Quantporo software and the soil organic carbon. Undisturbed soil were sampled to determine the physical attributes. The experimental design was in randomized blocks with three repetitions, anova was performed by Fisher and the means compared by Tukey test. No physical impediments were found for the roots performance in the Haplumbrept under conservationist management system, these favored the irregularity of the aggregates surface observed by the low values of aspect and roughness in the different tested diameter ranges. Both Caburé and Aguará genotypes showed good roots spatial distribution in the soil profile in both sowing seasons with an increase in carbon storage in the smallest diameter aggregates (here considered the aggregates of 4.76-1 mm). Caburé genotype is the best genotype adapted to the edaphoclimatic conditions evaluated because had a greater roots volume, area and length below to 0.15 m depth. |

Foram utilizados três genótipos de linho: Aguará e Caburé-Argentina e Dourada-Brasil, semeados em abril e maio em sistema de plantio direto sobre Cambissolo Húmico. No estágio de floração, o sistema radicular foi avaliado por análise de imagem utilizando o programa Safira. Os mapas de distribuição radicular foram obtidos por krigagem - geoestatística. Na fase de colheita, foram amostrados blocos de solo para análise da morfometria de agregados por imagem no programa Quantporo além do carbono orgânico. Amostras de solo preservadas foram amostradas para determinar os atributos físicos. O delineamento experimental foi em blocos casualizados com três repetições, a anova foi realizada pelo teste de Fisher e as médias comparadas pelo teste de Tukey. Não foram encontrados impedimentos físicos para o desempenho das raízes no Cambissolo sob sistema de manejo conservacionista, favorecendo a irregularidade da superfície dos agregados observada pelos baixos valores de aspecto e rugosidade nas diferentes faixas de diâmetro testadas. Os genótipos Caburé e Aguará apresentaram boa distribuição espacial das raízes ao longo do perfil do solo em ambas as épocas de semeadura, com um aumento no armazenamento de carbono nos agregados de menor diâmetro (considerados aqui os agregados de 4,76-1 mm). O genótipo Caburé se adaptou às condições edafoclimáticas avaliadas, pois apresentou melhor desempenho radicular abaixo de 0,15 m.UEL2020-09-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3840710.5433/1679-0359.2020v41n6p2523Semina: Ciências Agrárias; Vol. 41 No. 6 (2020); 2523-2540Semina: Ciências Agrárias; v. 41 n. 6 (2020); 2523-25401679-03591676-546Xreponame:Semina.
