Abstract :
Based on different water deficit treatments, cumulative function of sensitive index for winter wheat was established. The higher water sensitive index was in the period of 160-180 day after seeding, which reached 0.01. The results demonstrated that the cumulative function of sensitive index represented by a growing curve could describe the yield response to water deficit for winter wheat.
