A one-year＇s field experiment was conducted to study the correlation between the greenhouse gases emission and the root characteristics using early and late rice cultivars with different greenhouse gases emission fluxes in Hunan double cropping rice area.The results showed that CH4 emission flux was negatively correlated with root dry weight（P0.05） and amount of root exudates（P0.05） at the full tillering stage of early rice,and was negatively correlated with amount of root exudates（P0.01） in late rice.The N2O emission flux was negatively...
