Other claims from this paper (10)
- Observation Native embolism in lateral roots and branches of mature Populus euphratica trees was relatively high, with mean PLC above 50%.
- Observation Morning native embolism at branch level was lower than in the afternoon, with no significant difference.
- Observation Native embolism level in lateral roots of mature trees was higher at 200 m from the river bank than at the river bed, with significant differences.
- Observation The ks(max) value of mature trees at 200 m from the river bank was higher than at the river bed, not significantly.
- Association Lateral root native embolism level of seedlings increased under increased soil drought stress.
- Association Stomata conductance of seedlings decreased under increased soil drought stress.
- Observation Mature trees had significantly larger mean vessel diameter and mean hydraulic diameter than seedlings in lateral roots.
- Observation Seedlings had higher xylem vessel density than mature trees in lateral roots.
- Association Maximum hydraulic conductivity was closely correlated with mean vessel diameter and hydraulic diameter in lateral roots.
- Mechanism Higher native embolism in arid-grown Populus euphratica is beneficial, as it helps prevent excessive water loss and supports plant water status.
