Banana tree cultivation produces a large amount of pseudostem residues, which, due to their physical-chemical characteristics, can be an alternative in substrates composition for ornamental plants, in substitution for xaxim fiber, mainly when associated with fertilizers. This research aimed to evaluate biomass production, nutritional stage, and nutrients availability for ferns, testing substrates in xaxim fiber (XF) and banana tree pseudostem (BP), and fertilizations with N and P. The substrate proportions were sand:soil:XF and sand:soil:BP, in a relation of 1:1:2 in volume. Dosages tested were 0 mg dm<sup>-3; 68.5 mg dm<sup>-3; 137.0 mg dm<sup>-3; 205.5 mg dm<sup>-3; and 374.0 mg dm<sup>-3 of N and 0 mg dm<sup>-3; 97.7 mg dm<sup>-3; 195.4 mg dm<sup>-3; 291.9 mg dm<sup>-3; and 390.8 mg dm<sup>-3 of P2O5. The number of leaves produced by the fern did not differ significantly in response to substrates or N and P dosages. The same result was verified in most of the substrate and plant mineral evaluations. It was concluded that banana tree pseudostem could perfectly replace xaxim fiber as substrate component for ferns.</span></span></span></p> <p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">KEY-WORDS: <em>Polypodium persicifolium</em> var. <em>mettenii</em> Desv.; foliar analysis; mineral nutrients; <em>Dicksonia sellowiana</em>; alternative substrates.</span></span></span></p> <p class="MsoBodyText" style="margin: 0cm 0cm 0pt; line-height: 200%; text-align: justify; mso-pagination: none;"><!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } --></p><p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">A proibição do uso de substratos à base de fibra de xaxim, devido à sua matéria-prima (<em>Dicksonia sellowiana</em>) estar ameaçada de extinção, levou à necessidade de se selecionar substratos alternativos. A bananicultura gera um grande volume de resíduos de pseudocaule, que, por suas características físicoquímicas, podem ser uma alternativa na composição de substratos para plantas ornamentais, em substituição à fibra de xaxim, principalmente se associada à adubação. O presente trabalho objetivou determinar a produção de biomassa, estado nutricional e disponibilidade de nutrientes para samambaias, testando-se substratos contendo fibra de xaxim (FX) e pseudocaule de bananeira (PB), e adubação com N e P. Os substratos apresentaram proporções de areia:solo:FX e de areia:solo:PB, numa relação 1:1:2, em volume. Testaram-se doses de 0 mg dm<sup>-3; 68,5 mg dm<sup>-3; 137,0 mg dm<sup>-3; 205,5 mg dm<sup>-3; e 374,0 mg dm<sup>-3 de N e de 0 mg dm<sup>-3; 97,7 mg dm<sup>-3; 195,4 mg dm<sup>-3; 291,9 mg dm<sup>-3; e 390,8 mg dm<sup>-3 de P2O5. O número de folhas emitidas pela samambaia não diferiu, significativamente, em resposta aos substratos ou às doses de N e P2O5, verificando-se semelhante comportamento na maioria das avaliações minerais do substrato e da planta. Conclui-se que o PB é um promissor material a ser utilizado como componente de substratos para samambaias, em substituição à FX.</span></span></span></p> <p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;"><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><span style="font-style: normal;"><span style="font-weight: normal;">PALAVRAS-CHAVE: </span></span></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><em><span style="font-weight: normal;">Polypodium persicifolium</span></em></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><span style="font-style: normal;"><span style="font-weight: normal;"> var. </span></span></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><em><span style="font-weight: normal;">mettenii</span></em></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><span style="font-style: normal;"><span style="font-weight: normal;"> Desv.; análise foliar; nutrientes minerais; </span></span></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><em><span style="font-weight: normal;">Dicksonia sellowiana</span></em></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><span style="font-style: normal;"><span style="font-weight: normal;">;</span></span></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><em><span style="font-weight: normal;"> </span></em></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><span style="font-style: normal;"><span style="font-weight: normal;">substratos alternativos</span></span></span></span></span></span><span style="color: #000000;"><span style="text-decoration: none;"><span style="font-family: Times New Roman,serif;"><span lang="pt-BR"><em><span style="font-weight: normal;">.</span></em></span></span></span></span></span></span></span></p><p> </p> |
