Miniestaquia de <i>Grevillea robusta</i> A. Cunn. a partir de propágulos juvenis.

Abstract

O presente estudo teve como objetivo avaliar a sobrevivência e a produtividade de minicepas no sistema de tubetes e o efeito do ácido indolbutírico (AIB) no enraizamento de miniestacas de Grevillea robusta. O experimento foi conduzido em Colombo, PR, com minicepas formadas partindo de mudas obtidas de sementes, as quais foram cultivadas no sistema de tubetes, durante o período de um ano. A sobrevivência das minicepas, após 15 coletas, foi de 100% com produtividade média de 1,7 miniestacas por minicepa e 4030 miniestacas por metro quadrado ao ano. As taxas médias de enraizamento foram 83, 79, 75 e 72% para os tratamentos com 0, 1000, 2000 e 4000 mg L-1 de AIB respectivamente, sendo os melhores níveis obtidos sem aplicação exógena de AIB. Com base nesses resultados, conclui-se que a miniestaquia de propágulos juvenis é uma opção para produção de mudas de Grevillea robusta durante o ano inteiro, sem a necessidade de aplicações de reguladores de crescimento, além de ser uma importante ferramenta para adaptação dos protocolos de propagação vegetativa em materiais adultos selecionados.
