- Intervention effect Elevated CO2 and temperature decreased leaf nitrogen content in three woody species in May 2009 and June 2011.
- Intervention effect Elevated CO2 and temperature decreased leaf nitrogen content of B. latissimum and I. dichotoma under treatment in 2009 and 2011.
- Intervention effect Elevated CO2 and temperature did not significantly affect leaf nitrogen content of C. virosa and V. raddeana in 2009.
- Intervention effect Elevated CO2 and temperature increased leaf nitrogen content of C. virosa under treatment in 2011.
- Intervention effect Elevated CO2 and temperature decreased leaf nitrogen content of V. raddeana under treatment in 2011.
- Intervention effect Elevated CO2 and temperature did not change leaf carbon content in 2009 in the six species other than P. ramosissimus.
- Intervention effect Elevated CO2 and temperature did not change leaf carbon content of Q. gilva in 2011.
- Intervention effect Rising CO2 concentration and temperature increased leaf carbon content of the remaining six species in 2011.
- Intervention effect Elevated CO2 and temperature lowered the leaf C:N ratio of C. virosa in both 2009 and 2011.
- Observation The leaf C:N ratio of V. raddeana decreased by 16.4% from the previous year.
- Observation The leaf C:N ratio of V. raddeana increased by 28.9% in 2011.
- Intervention effect Elevated CO2 and temperature increased the C:N ratios of the other five species in 2009 and 2011.
- Intervention effect Elevated CO2 and temperature raised leaf chlorophyll contents of Q. gilva and H. hamabo in 2009 and 2011.
- Intervention effect Elevated CO2 and temperature raised the chlorophyll ratio of P. ramosissimus in 2009.
- Intervention effect The chlorophyll ratio of P. ramosissimus in the treatment showed the opposite response in 2011.
- Intervention effect Elevated CO2 and temperature did not change leaf chlorophyll contents of C. virosa, V. raddeana and I. dichotoma in 2009.
- Intervention effect Rising CO2 concentration and temperature decreased leaf chlorophyll contents of C. virosa, V. raddeana and I. dichotoma in 2011.
- Association Woody species seem more sensitive than herb species to the rise of CO2 concentration and temperature.
