Other claims from this paper (9)
- Observation Male Populus cathayana had a higher carbon fixation capacity, with higher leaf gas exchange and fluorescence traits, after severe long-term defoliation under deficient N.
- Observation Males had higher leaf abscisic acid, stomatal conductance and leaf sucrose phosphate synthase activity.
- Intervention effect Under N-deficient conditions, males accumulated more than 131.10% and 90.65% more root starch than control males.
- Intervention effect Under N-deficient conditions, females accumulated more than 40.55% and 52.81% more root starch than control females.
- Observation Males allocated less non-protein N (NNon-p) to leaves.
- Observation Males had higher photosynthetic nitrogen use efficiency.
- Observation Males had higher glutamate dehydrogenase (GDH).
- Observation Males had higher leaf GDH expression.
- Observation Females had higher leaf jasmonic acid concentration and non-protein N (NNon-p).
