Abstract:
|
Eight wheat varieties (Chinese Spring, Pavon, Gabo, Saleem-2000, Zamindar-04, Siren, NR-264 and Marvi) were compared for their response to exogenous application of abscisic acid (ABA), Water Stress (WS) and Control (C) during invitro condition. Their responses were studied in the form of seedlings growth and antioxidant enzymes. Exogenous application of ABA reflected ameliorating effect on catalase activity. Water stress treatment led to increase in levels of catalase except Pavon. Increased activity of antioxidant enzymes showed tolerance capacity under water stress. Correlation coefficient analysis reflected negative and significant relationship between total protein contents and peroxidase and catalase. Further, investigations are needed to enhance the understanding on the effect of different abiotic stresses and growth hormones during early seed development.
Key words: Abscisic acid, catalase, correlation, peroxidase, water stress and wheat, ,
