Abstract:     The  maize  (Zea  mays  L.,  Poaceae)  is  a  high  productivity  plant,  but  its  agricultural  yield  is compromised  in  areas  with  soil  salinity  problems.  This  study  aimed  to  evaluate  the  performance  of  maize plants  (AL  Bandeirantes  cultivar)  submitted  to  different  levels  of  salinity.  The  experiment  was  conducted  in greenhouse  conditions  under  completely  randomized  design,  with  4  treatments  (0,  50,  100  and  150  mM  of NaCl). An additional group of plants was not exposed to NaCl (control). The plants were evaluated for height, root  volume,  shoot  and  root  dry  weight,  shoot/root ratio,  relative  water  content  and  proline  concentration  in leaves.  The  NaCl  reduced  the  dry  weight  and  the  root  volume  in  comparison  with  that  observed  for  the control.  The  plants  height  was  affected  only  after 21  days  of  exposure  to  salt  stress,  while  no  significant difference  in  relative  water  content  was  observed  among  treatments.  The  proline  accumulation  was expressive  in  the  plants  treated  with  150  mM  of  NaCl,  indicating  a  mechanism  for  regulating  osmotic.  Salt stress did not affect the survival of the AL Bandeirantes cultivar, as was observed by plants development at all concentrations applied.

Resumo:    O  milho  (Zea  mays  L.,  Poaceae)  é  uma  planta  de  alta  produtividade,  mas  o  seu  rendimento agrícola  é  comprometido  em  áreas  com  problemas  de  salinidade  do  solo.  Este  estudo  teve  como  objetivo avaliar  o  desempenho  de  plantas  de  milho  (cultivar AL  Bandeirantes)  submetidas  a  diferentes  níveis  de salinidade.   O   experimento   foi   conduzido   em   condições   de   casa   de   vegetação   sob   delineamento inteiramente casualizado, com 4 tratamentos (0, 50, 100 e 150 mM de NaCl). Um grupo adicional de plantas não foi exposto ao NaCl (controle). As plantas foram avaliadas quanto à altura, volume radicular, peso seco dos  brotos  e  raízes,  razão  parte  aérea/raiz,  teor  relativo  de  água  e  concentração  de  prolina  nas  folhas.  O NaCl reduziu o peso seco e o volume radicular em comparação com o observado no controle. A altura das plantas foi afetada somente após 21 dias de exposição ao estresse salino, enquanto que no teor relativo de água não foi observada diferença significativa entre os tratamentos. O acúmulo de prolina foi expressivo nas plantas tratadas com 150 mM de NaCl, indicando um mecanismo de regulação osmótica. O estresse salino não  afetou  a  sobrevivência  da  cultivar  AL  Bandeirantes,  como  foi  observado  pelo  desenvolvimento  das plantas em todas as concentrações aplicadas.
