Porta-enxertos de videira sob déficit hídrico: respostas em biomassa, variáveis bioquímicas e trocas gasosas

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

Os recursos hídricos, especialmente em regiões semiáridas, devem ser utilizados com o emprego de tecnologias que permitam aumentar a eficiência e uso da água para irrigação. Uma estratégia para lidar com esse problema é o uso de porta-enxertos tolerantes à seca. Com o objetivo de selecionar porta-enxertos de videira adequados para o cultivo em regiões semiáridas, com base na biomassa, variáveis bioquímicas e nas trocas gasosas, o experimento foi conduzido no Campo Experimental de Bebedouro, pertencente à Embrapa Semiárido, em Petrolina-PE. Foram utilizados os portaenxertos ‘Paulsen1103’, ‘SO4’, ‘IAC 313’, ‘IAC 572’, ‘IAC 766’, ‘Ramsey’ e ‘101-14 MgT’ submetidos a três lâminas de irrigação (100, 50 e 20% da ETo). O delineamento experimental foi em blocos casualizados com quatro repetições, em parcelas subdivididas, com a parcela principal sendo a lâmina de irrigação e a subparcela os portaenxertos. Características bioquímicas, de biomassa e relacionadas às trocas gasosas foram utilizadas para seleção dos melhores portaenxertos quanto à tolerância à seca, por meio de análise multivariada de componentes principais (PCA) e análise de variância. Os portaenxertos ‘IAC 313’ e ‘IAC 766’ destacaram-se pela maior síntese de prolina radicular, o ‘IAC 766’ apresentou melhor resultado para síntese de sacarose foliar, enquanto ‘Paulsen1103’ se destacou em prolina foliar, carotenoide e razão clorofila total/carotenoide. Pode-se concluir que os porta-enxertos ‘IAC 313’, ‘IAC 766’ e ‘Paulsen 1103’ apresentam melhor desempenho quanto às características estudadas e, portanto, são uma escolha válida para cultivo da videira no Submédio do Vale do São Francisco, especialmente em condições de déficit hídrico.
