e0“This study was carried out on Populus euphratica Oliv.”
e5“The ks(max) value and native embolism level in lateral roots of mature P.euphratica trees at 200 m from the river bank were higher than those at the river bed”
e6“there were significant differences(P0.05),between the native embolism level but not the ks(max) value”

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.
- 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.
- Association Lateral root native embolism and stomata conductance of seedlings were significantly negatively correlated.
- 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.
