Fig. 4. — Relationships between leaf xylem ABA concentration ([X-ABA]_leaf) (A, B) and leaf water potential (C, D) and soil water content from both sides (left and right) of the root system of tomato plants. In PRD-Fixed plants, left and right sides corresponded to wet and dry parts of the root system while, in PRD-Alternated plants, they corresponded to the newly-drying and just re-watered parts of the root system. In PRD-Alternated plants measurements were taken 2h and 6h after irrigation was alternated. Each point represents a single leaf and regression lines were fitted where significant (P <0.05). NC means not correlated.
