The aim of this study was to test the hypothesis that salinity can affect indirectly the nitrate acquisition by a negative modulation triggered by glutamine accumulation. Cowpea plants were exposed to a mild NaCl concentration (50 mM) in order to res

Redução assimilatória de NO-3 em plantas de cajueiros cultivados em meio salinizado NO-3 assimilatory reduction in cashew plants grown in salinized medium

Autor: Ricardo A. Viégas, Joaquim A. G. da Silveira, Lígia M. de M. Silva, Pedro R. A. Viégas, José E. Queiroz, Iza M. A. Rocha

Publikováno v: Revista Brasileira de Engenharia Agrícola e Ambiental-Agriambi, Vol 8, Iss 2-3, Pp 189-195 (2004)

Com o objetivo de se avaliar os efeitos e mecanismos iniciais da ação da salinidade sobre a redução de NO-3 e a acumulação de solutos nitrogenados, plantas de cajueiro (Anacardium occidentale L.), CCP - 1001, com 42 dias de idade foram cultivad
