Other claims from this paper (10)
- Intervention effect Under single or combined Pb and Cr stress, plant height and ground diameter first increase and then decrease with heavy metal concentration.
- Intervention effect Under single or combined stress, SOD and POD activities first increase and then decrease with heavy metal concentration.
- Intervention effect Under single or combined stress, soluble protein and soluble sugar contents first increase and then decrease with heavy metal concentration.
- Intervention effect Free proline, malondialdehyde and relative electrical conductivity gradually increase with heavy metal concentration.
- Intervention effect As Pb and Cr concentrations increase, their contents rise in roots, stems and leaves.
- Observation B. acutangula has a strong root enrichment capacity for Pb and Cr.
- Observation B. acutangula has a weak translocation ability for Pb and Cr.
- Intervention effect Under combined Pb-Cr stress, the two metals interact primarily antagonistically.
- Intervention effect The P2 treatment group (Pb 200 mg·kg-¹) has the highest comprehensive tolerance value.
- Observation B. acutangula shows strong adaptive potential when Pb concentration does not exceed 200 mg·kg-¹.
