Fig. 4From: Morphological and physiological responses of Heteropogon contortus to drought stress in a dry-hot valleyBound water/free water ratio (a), total water content (b), relative water content (c) and leaf water potential (d) of Heteropogon contortus on different days under four different water levels. Values represent the mean ± standard error (n = 3) and RW represents the day after re-wateringBack to article page
