Title

Other claims from this paper (7)
- Intervention effect Leaf senescence developed about 12 days after drought treatment started.
- Intervention effect Drought-associated senescence involved decreasing photosynthesis, Fv/Fm and chlorophyll content.
- Observation Senescence marker genes showed differential expression during drought-associated senescence.
- Intervention effect The C:N ratio was significantly enhanced 10 to 12 days into drought treatment.
- Association Older lower leaves senesced and had higher C:N ratios.
- Intervention effect Excess sugar with limited nitrogen promoted drought-induced leaf senescence.
- Mechanism Carbon/nitrogen balance may regulate drought-induced leaf senescence.
