Other claims from this paper (15)
- Intervention effect Salt treatment reduced leaf area, shoot and root weights relative to plants without added NaCl.
- Intervention effect Salinity reduced the osmotic potential of wheat seedlings.
- Intervention effect Salinity had little effect on water potential of wheat seedlings.
- Intervention effect Turgor pressure was not much affected by salt.
- Observation Genotypes varied in all characteristics studied, especially in leaf and root Na accumulation.
- Association Amphiploids and the 5Eb addition line accumulated the least Na compared with other genotypes.
- Association Roots accumulated lower quantities of Na than leaves.
- Intervention effect Genotype K contents were not affected by salt treatment.
- Intervention effect Stomatal conductance declined in salt-treated seedlings.
- Intervention effect ABA content increased in salt-treated seedlings.
- Association The amphiploids and 5Eb addition line were the most salt-tolerant for growth.
- Association Glennson 81 was the most salt-susceptible for growth.
- Association Tetrasomic 2B and tetrasomic 5B lines were the most salt-susceptible for growth.
- Intervention effect Addition of homoeologous group 2 and 5 chromosomes reduced salt tolerance relative to the euploid Chinese Spring.
- Mechanism Salt tolerance may be due to the ability of Thinopyrum bessarabicum chromosome 5Eb to exclude Na ions from leaves and roots.
