Abstract EN
Selenium (Se) is an essential micronutrient with a range of physiological and antioxidative properties.
Reports regarding effect of Se application on plants growth and development are not consistent.
The identification of effective Se dose and application method is crucial for better understanding of Se translocation within crop plants under drought stress.
The present study aimed at investigating the role of Se supplementation in improving the drought tolerance potential of wheat at early growth stages.
Two wheat genotypes (Kohistan-97 and Pasban-90) were grown in plastic pots (8 × 12 cm) in green/wire-house experiments.
Results demonstrated that the growth and biomass of seedlings increased at high Se foliar concentrations and decreased at low and high Se fertigation levels.
The seedlings exhibited the highest values for plant height stress tolerance index (PHSI), root length stress tolerance index (RLSI), dry matter stress tolerance index (DMSI), and fresh matter stress tolerance indices (FMSI) at Se fertigation level of 7.35 μM, whereas Se foliar treatment of 7.06 μM resulted in maximum values for these indices.
The seedlings foliarly sprayed with Se maintained higher DMSI and FMSI than those fertigated with Se which suggests that Se foliar spray is more effective than Se fertigation for improving drought tolerance.
