Abstract
The yield and photosynthetic characteristics of flag leaf of different drought resistance wheat varieties under different water conditions were studied.The results showed that the yield of Luohan No.2 was significantly higher than Wenmai No.6 under drought stress.The photosynthetic rate,transpiration rate,stomatal conductance and intercellular CO2 concentration of the two varieties with irrigation were higher than that under drought stress.The decreasing rates of photosynthetic rate,transpiration rate and stomatal conductance of Luohan No.2 were lower than Wenmai No.6 under water stress.
