Resumo: | A well-developed root system is a very important characteristic of rootstocks. Initial plant characterization is a potential technique to highlight cultivars with desirable root architecture for the diversification of rootstocks in the national citriculture. Thus, the aim of this study was to evaluate the initial shoot development and root architecture of citrus cultivars used as rootstocks. Seeds from five rootstocks, ‘Cleopatra’ mandarin, ‘Rangpur’ lime, ‘Rough’ lemon, ‘C13’ and ‘Troyer’ citranges, were sown in black polyethylene bags. A completely randomized block design with five replications and one plant per plot was applied. At 30 and 45 days after emergence, shoots and roots were collected for analysis. Shoot analysis measured the total number of leaves, leaf area, stem diameter, plant height, and fresh and dry matter weights. Root analysis evaluated fresh and dry matter weights and root architecture by image analysis, which recorded root traits including primary, secondary, and tertiary root numbers; length and total volume; and the percentage of secondary roots present in the upper third of the primary root. Shoot and root data of fresh and dry weights were submitted to variance analysis and compared using Tukey’s test (5%). The remaining root data were standardized for variance 1 and studied through principal component analysis. The ‘C13’ citrange showed good shoot development, with greater leaf area, plant height, stem diameter, and shoot fresh and dry matter weights during both evaluation periods, followed by the ‘Troyer’ citrange. The ‘Cleopatra’ mandarin had the smallest shoot and root development during both evaluation periods, presenting lower primary root, secondary root, and root volume than other cultivars evaluated at the same time. The ‘Troyer’ citrange had fewer roots in the upper third of the primary root and a higher root insertion angle. |

A caracterização inicial das plantas é uma técnica que apresenta potencial para detecção de cultivares com arquitetura desejável de raízes para uso na diversificação dos porta-enxertos da citricultura nacional. Com isso, o objetivo do estudo foi avaliar o desenvolvimento inicial da parte aérea e a arquitetura de raiz de cinco cultivares de citros usadas como porta-enxertos. Sementes de cinco porta-enxertos, tangerina ‘Cleópatra’, limão ‘Cravo’, limão ‘Rugoso’, citrange ‘C13’ e ‘Troyer’, foram semeadas em sacolas pretas de polietileno. Foi utilizado delineamento experimental de blocos inteiramente casualizados, com cinco repetições e uma planta por bloco. Aos 30 e 45 dias após emergência a parte aérea e as raízes foram coletadas para análise. As análises de parte aérea avaliaram número total de folhas, área foliar, diâmetro do caule, altura da planta, massa fresca e seca. Análises de raízes avaliaram massa fresca e seca e arquitetura de raízes por análise de imagem, que avaliou características como, número de raízes primárias, secundários e terciárias, comprimento e volume total de raízes e porcentagem de raízes secundárias presentes no primeiro terço da raiz principal. Os dados de parte aérea e massa fresca e seca de raiz foram submetidos à análise de variância e comparados usando teste de Tukey (5%). O restante dos dados de raiz foram padronizados para a variância 1 e estudados pela análise de componentes principais. O citrange ‘C13’ apresentou bom desenvolvimento de parte aérea, com maior área foliar, altura de planta, diâmetro de caule e massa fresca e seca de parte aérea em ambos períodos avaliados, seguido pelo citrange ‘Troyer’. A tangerina ‘Cleópatra’ apresentou menor desenvolvimento radicular e de parte aérea nos dois períodos avaliados, com menor desenvolvimento de raízes primárias, secundárias e menor volume, comparada com as outras cultivares avaliadas no mesmo período. O citrange ‘Troyer’ apresenta poucas raízes no terço superior e maior ângulo de inserção das raízes.UEL2019-06-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3011110.5433/1679-0359.2019v40n4p1393Semina: Ciências Agrárias; Vol. 40 No. 4 (2019); 1393-1404Semina: Ciências Agrárias; v. 40 n. 4 (2019); 1393-14041679-03591676-546Xreponame:Semina.
