Abstract: The chlorophyll content of domestic and overseas spring wheat in different ecosystem and its connection with drought resistance have been researched under irrigation condition in different year,the experimental results as the comparison indicated that the chlorophyll content of dry land is lower about 5.37 than that of wet land in the condition of irrigation.Under the dry stress condition,the dry stress treated chlorophyll content went down 2.39 compared with comparison and chlorophyll content of dry land went down 1.89 compared with that of wet land.That also has been found there is less discrepancy among different years of chlorophyll content.Chlorophyll content correlated Δ positively.And chlorophyll content correlated drought resistance tightly.

Key words: Wheat, Chlorophyll content, Carbon isotope discrimination( Δ) , Dry stress, Drought resistance
