• Hydraulic Vulnerability Segmentation Mechanism Helps Compound-leaved Tree Species Withstand Drought Stress

  Compound-leaved tree species usually have higher productivity compared with simple-leaved species. That is because trees with compound-leaves generally have higher water transfer efficiency, and thus higher potential rate of photosynthetic carbon assimilation. This finding had been revealed in a research led by Prof. HAO Guangyou of the Plant Physiology and Ecology Group at the Institute of Applied Ecology of the Chinese Academy of Sciences.
