Other claims from this paper (17)
- Intervention effect Water stress decreased dry mass accumulation in poplars.
- Intervention effect Water stress increased the relative allocation to roots in poplars.
- Intervention effect Water stress increased osmolyte contents in poplars, including total amino acids.
- Intervention effect Water deficit increased electrolyte leakage, malondialdehyde and carbonyl content in poplars.
- Intervention effect Water deficit increased hydrogen peroxide content in poplars.
- Intervention effect Water stress enhanced activities of ascorbate peroxidase, guaiacol peroxidase and glutathione reductase in poplars.
- Intervention effect Water stress enhanced ascorbic acid content in poplars.
- Intervention effect Water stress reduced amounts of leaf pigments in poplars.
- Association P. przewalskii allocated more to root dry mass than P. cathayana under water stress.
- Association P. przewalskii had a higher net photosynthesis rate than P. cathayana under water stress.
- Association P. przewalskii accumulated more osmolytes than P. cathayana under water stress.
- Association P. przewalskii had stronger antioxidant activities than P. cathayana under water stress.
- Association P. przewalskii had a lower chlorophyll/carotenoid ratio than P. cathayana under water stress.
- Association P. przewalskii had lower electrolyte leakage, MDA and C=O than P. cathayana under water stress.
- Association P. przewalskii had lower hydrogen peroxide content than P. cathayana under water stress.
- Observation The two poplar species differed significantly in the extent of morphological and biochemical changes.
- Mechanism P. przewalskii from high altitude may have more efficient protective mechanisms than P. cathayana from low altitude.
