Morphological, anatomical and physiological responses of Campylotropis polyantha (Franch.) Schindl. seedlings to progressive water stress

▶ The seedlings present linearly lowering responses in morphological and physiological traits. ▶ WUE presents parabola relationship with drought intensity. ▶ Around 25.6% and 12.3% were thresholds separately limiting and stopping growth. ▶ The shrub seedlings take avoidance and tolerance mechanism to withstand progressive drought.
