Other claims from this paper (14)
- Intervention effect Strontium treatment significantly decreased biomass and root activity of Vicia faba seedlings.
- Intervention effect Strontium treatment caused almost no root necrosis in Vicia faba seedlings.
- Intervention effect Strontium significantly inhibited taproot length, lateral root number and plant height of V. faba.
- Intervention effect Strontium significantly inhibited branching number and internodes number of V. faba.
- Intervention effect Strontium made the apical dominance of the taproot and terminal bud of Vicia faba more obvious.
- Intervention effect Accumulated Sr decreased leaf area, dry weight and stomatal density of Vicia faba.
- Intervention effect Accumulated Sr decreased stomatal aperture of Vicia faba.
- Intervention effect Accumulated Sr increased guard cell length of Vicia faba.
- Mechanism Changes in stomatal morphology may be a positive regulation that reduces water loss in Vicia faba.
- Intervention effect Vicia faba increased non-photochemical quenching and peroxidase and ascorbate peroxidase activities under Sr stress, protecting the photosynthetic structure.
- Intervention effect Low Sr concentration (250 mg·L−1) promoted photochemical efficiency and electron transfer of PSII in Vicia faba.
- Intervention effect Sr at 250–1,000 mg·L−1 inhibited net photosynthetic rate, transpiration rate and stomatal conductance in Vicia faba leaves.
- Mechanism Net photosynthetic rate in Vicia faba is affected by both stomatal and non-stomatal factors.
- Intervention effect Sr did not cause significant damage to the PSII function of Vicia faba.
