Physiological metabolism of cotton changed dynamically and responded differently to long term elevated [CO2] (EC) and temperature (ET) during different growth times.
DMC and C/N ratio were markedly increased by the combination of ETEC, but leaf N was reduced by ETEC.
EC enhanced sugar, starch, TNC, total phenolic contents but they were significantly decreased by ETEC.
Specific amino acid content changed differently in response to [CO2] and temperature.
There were differently interactive effects between [CO2] and temperature during different growth times.
