%X The field experiment of clipping stress(simulated herbivory) on the compensatory effects of spring wheat ( Triticum aestivum L.) was conducted in 1995 in semi arid region of Gansu Loess Plateau. The results showed that the yield of spring wheat was decreased by the clipping. The negative effects at the jointing stage was more serious than that at the seeding stage. A more heavy degree of the clipping resulted in the more serious effect at the seeding stage. However, the yield overcompensation for clipping the first three leaves at the jointing stage was expressed due to the change of source sink relations and resulted an increase of the yield. The reason was probably because of cutting away the tedious leaves in the drought.
