Abstract:: To explore the response of hydraulic resistances in the soil-Robinia pseudoacacia system to water stress, changes of transpiration rate, root water potential, leaf water potential of the 2-year-old Robinia pseudoacacia and hydraulic resistances of soil-Robinia pseudoacacia system were identified and calculated by pot experiments under 8 water gradients which were 30%, 40%,…, and 100% of field capacity. The results showed that:(1)transpiration rate, root water potential, and leaf water potential of Robinia pseudoacacia showed a trend of increasing and then remaining stable with the improvement of soil water content, and transpiration rate increased in the range of 30%～70% of field capacity, while root water potential and leaf water potential increased in the range of 30%～50% of field capacity;(2)soil resistance, total root resistance, plant transportation resistance and leaf-air resistance decreased with the increment of the water content, especially in the range of 30%～50% of field capacity, and they changed slightly when the soil water content was above 50%; the values of each resistance decreased in the order: July>October>August>September;(3)the total hydraulic resistance of the soil-Robinia pseudoacacia system was similar to leaf-air resistance, as leaf-air resistance accounted for more than 96.0% of its value and played a predominant role in the adjustment of total hydraulic resistance. According to these results of the research, we speculate the plants of Robinia pseudoacacia can ensure heathy and sustainable growth in the soil with greater than 50% of field capacity.
