Abstract:
The present experiment was conducted at Agricultural University Peshawar, Khyber Pukhtun Khwa Pakistan, to study the response of 6 wheat genotypes to foliar ABA applications and induced salinity stress for their proline production using completely randomized design (CRD) with three replications. Shoot proline contents were significantly (p≤0.05) affected by genotypes, salinity levels, ABA application and their all possible interactions. Maximum proline content and yield attributes were produced by SR-40 when compared with other genotypes under study. High salinity stress (10 dSm-1) had a positive effect on proline synthesis of wheat genotypes. Exposure of plants to both salinity stress and foliar application of ABA resulted in elevated levels of proline and better yield when compared with other treatments.
