Resposta de plantas micropropagadas de abacaxizeiro à inoculação de bactérias diazotróficas em casa de vegetação

Abstract: O objetivo deste trabalho foi selecionar e avaliar bactérias diazotróficas isoladas de abacaxizeiro (Ananas comosus (L.) Merril) no desenvolvimento de cultivares micropropagadas da mesma espécie em casa de vegetação. Plantas da cultivar Perolera foram submetidas à inoculação com Asaia bogorensis (AB219) e cultivadas em tubetes, durante 145 dias, com as misturas: casca de arroz carbonizada, folha de carnaubeira triturada e vermicomposto; casca de arroz carbonizada, pó da casca do coco maduro e vermicomposto; ca… Show more

“…The colonization of 'Champaka' plants by A. bogorensis (strain AB219) was observed in this study, confirming previous reports (Weber et al 2003a(Weber et al , b, 2004. The presence of the potential diazotrophic bacterium was also detected in the uninoculated control plants.…”

“…Por sua vez, o contraste entre plantas inoculadas do AB213 vs. controle não atingiu nível satisfatório de significância no teste t (p = 0,165) (Tabelas 3). As contribuições diferenciadas dos isolados de bactérias utilizadas sobre a produção da cultivar Cayenne Champac (Tabela 2) se somam às observações feitas para mudas das cultivares Pérola e Smooth Cayenne micropropagadas, quando inoculadas dos mesmos isolados (Weber et al, 2003a), e para mudas da cultivar Cayenne Champac inoculadas do AB219 (Weber et al, 2003b), permitindo sugerir que é vantagem inocular bactérias diazotróficas em mudas micropropagadas do abacaxizeiro.…”

“…With the objective of increasing yield and optimization of acclimation phase of ornamental seedlings, the following has been studied: the use of fitted substrates (Yamamoto et al, 2007;Lima et al, 2008) and containers (Cunha et al, 2005), the association between plants with micorhizal fungi and diazotrophic bacteria (Weber et al, 2003;Baldotto, 2010), the use of growth regulators (Lima et al, 2008), among others. The objective of such efforts is to accelerate plant growth and to reduce the impact of transference from nursery to the field, increasing yield and seedling quality in less time and at lower costs.…”
