- Abstract
Salinity is most significant abiotic factor limiting sesame growth, physio-chemical mechanisms and productivity. To address this issue a pot trial was conducted to check the effectiveness of hydropriming (water; control), thiourea (150 mM) seed priming under normal (10.8 mM) and saline conditions (70 mM). The seeds of two varieties (TS-05 and TH-06) was sown at Botany Garden, University of Agriculture, Faisalabad. Results showed that salinity decreases the growth (root and shoot parameters) impaired the balance between antioxidants (superoxide dismutase, catalase, peroxidase) and oxidants (hydrogen peroxide and malondialdehyde), and lessened the uptake of essential minerals (potassium and calcium) irrespective of varietal differences. However, the performance of TH-6 was better than TS-5. In addition, the seed priming of thiourea enhanced the sesame photosynthetic pigments and efficiency, secondary metabolites production, antioxidant machinery, and nutrient uptake in both varieties which increased growth an development as a result. So, thiourea seed priming is an effective strategy to counteract the negative effects of salt stress by improving tolerance mechanisms.
