Exogenously supplied amino acids and water deficits inZea mays cultivars

Abstract

Wilting of maize seedlings was significantly delayed in the presence of amino acids supplied in the ambient medium along with different levels of osmotic stress. Water saturation deficit (WSD) values at all stress levels were lower in the presence of exogenous amino acids, however, the effect was much clearer in resistant cv. Ageti-76 as compared to susceptible cv. Vijay under similar conditions. The effectiveness of proline in the external medium was in no way better than other amino acidse.g. serine, asparagine, alanine and cystine.
