Abstract

The broad spectrum protective effects of the non-protein amino acid b -aminobutyric acid (BABA) against numerous plant stresses has been well-documented in the literature. In this study the interaction between BABA (0, 300mM) and drought (control, mild and severe stress) were studied. Results showed that rapeseed plants which were under DROUGHT STRESS had lower percentage of membrane stability index (MSI) and relative water content (RWC), higher lipid peroxidation products when compared with control plants. Pretreatment of plants with BABA increased the MSI and RWC and decreased the amount of aldehydes in water stress plants. H2O2 content was increased under DROUGHT STRESS, pretreatment of plants with BABA decreased the amount of hydrogen peroxide. In DROUGHT STRESS condition, activity of SOD, APX, GR and POD were elevated over the controls while CAT activity decreased. In plants which pretreated with BABA and then exposed to DROUGHT STRESS the activity of mentioned enzymes increased.
