Resumo: The cupuassu (Theobroma grandiflorum) stands out as an important recently domesticated Amazon fruit. Although the substrate is a prime factor for plantlet development, there are few recommendations for cupuassu plantlet production. The objective of this work was to evaluate the influence of different substrates on cupuassu germination and seedling growth. Seven substrates were tested in greenhouse conditions: vegetable soil + sand (1:1), vegetable soil, bioplant®, bioclone®, plugmix®, sand and vermiculite. The following germination and seedling traits were evaluated: germination speed index, length and dry mass of roots and aerial parts; using a completely randomized design, with seven treatments and four replications of fifteen seeds. The individual averages were compared by the Scott-Knott test and the substrate recommendation was done using canonical variables. Bioclone® was the substrate that most positively influenced the seedlings development.

Um dos fatores determinantes para produção de mudas é a recomendação do substrato mais apropriado e, para espécies nativas, esta informação ainda é escassa. O objetivo deste trabalho foi avaliar o efeito de diferentes substratos na velocidade de germinação das sementes e no crescimento das mudas de cupuaçu. O trabalho foi realizado em casa-de-vegetação, sendo testados sete substratos: terra vegetal + areia (1:1), terra vegetal, bioplant®, bioclone®, plugmix®, areia e vermiculita. Foram avaliadas as características: índice de velocidade de emergência (IVE), comprimento da raiz (CR), comprimento da parte aérea (CPA), biomassa seca da raiz (BSR) e biomassa seca da parte aérea (BSPA), em delineamento experimental inteiramente casualizado com sete tratamentos, com quatro repetições de 15 sementes. As médias dos efeitos de substrato foram agrupadas pelo teste de Scott-Knott e a recomendação dos substratos foi realizada com o auxílio da técnica multivariada de variáveis canônicas. O substrato bioclone® se destacou na maioria das características de germinação e qualidade das mudas avaliadas.Universidade Estadual de Maringá2009-08-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/309210.4025/actasciagron.v31i4.3092Acta Scientiarum.
