Other claims from this paper (13)
- Association Specific root length, tissue density and tip number increased with orchard age.
- Association Root diameter, carbon concentration and C:N ratio decreased with age.
- Association Root traits varied significantly on PC1 along the age gradient.
- Association Root exudation rates differed significantly among ages and were most strongly associated with DOC and DOC:TDN.
- Association Carbon, nitrogen and sugar exudation initially increased then decreased, peaking at 3 or 5 years.
- Association Organic acid exudation initially increased then decreased, peaking at 3 or 5 years.
- Association Exudation was not significantly related to root chemical traits.
- Association Path modeling linked age to exudation directly and indirectly through traits, soil properties and microbial biomass.
- Association Root traits became more strongly associated with carbon exudation as age increased.
- Association Nitrogen exudation shifted from links to nutrient availability toward microbial biomass.
- Mechanism Nutrient availability and root traits jointly shape age-related exudation responses.
- Observation Absorptive root acquisition shifts from structural emphasis to efficiency optimization.
- Observation Exudate composition persists while rates diverge with development.
