CONCLUSÕES

Prolina pode ser considerada atenuante indicador de estresse salino em plantas jovens de cana-de-açúcar submetidas ao estresse salino. A cv. IAC 87-3396 apresenta maior peroxidação lipídica sob estresse salino enquanto a cv. SP 81-3250 mostra melhor recuperação, demonstrada pela diminuição dos teores de peróxido de hidrogênio e ácido malondialdeído, além de manter o crescimento das plantas menos alterado em salinidade severa. A cv. IAC 87-3396 é mais suscetível ao estresse salino que a cv. SP 81-3250.
