Resumo: | Clonal production of eucalyptus seedlings has made considerable progress in recent years. Significant developments have taken place in irrigation and fertilization systems as well as in management of clonal miniorchards. However, the proportion of leaf area in stem minicuttings remains almost the same as that used in macrocutting systems. This work aimed to evaluate the effect of leaf area reduction on seedling production of eight eucalyptus clones. The experiment was conducted over a period of 105 days using a randomized block design and three replicates in an 8 x 4 factorial arrangement, with eight clones and four leaf reduction levels (0%, 25%, 50% and 75%). Variables evaluated included height, root collar diameter, shoot and root dry matter and relationships between these variables. Experimental results demonstrated that clones behaved differently as to leaf reduction and that the 0% reduction level can be adopted in most clones being evaluated. |

Grandes avanços foram obtidos nos sistemas de irrigação, de fertilização e no manejo do minijardim clonal. Entretanto, a proporção de área foliar das miniestacas continua praticamente a mesma que se utilizava no sistema de macroestaquia. Objetivou-se, no presente estudo, avaliar o efeito da redução da área foliar na produção de mudas de oito clones de eucalipto. O experimento foi conduzido por 105 dias no esquema fatorial 8 x 4, com oito clones, quatro níveis de redução foliar (0, 25, 50 e 75 %) em delineamento em blocos casualizados e três repetições. Avaliouse a altura, o diâmetro do coleto, a massa da parte aérea e de raiz e relações entre estas variáveis. Os resultados desse experimento demonstram que os clones comportaram-se de forma distinta em relação à redução foliar e que o nível de 0 % de redução foliar pode ser adotado para a maioria dos clones avaliadosCERNE2015-05-142017-08-01T20:15:14Z2017-08-01T20:15:14Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/129SANTANA, R.
