Description: |
Biophysical characteristics of sapwood and outer parenchyma water storage compartments were studied in stems of eight dominant Brazilian Cerrado tree species to assess the impact of differences in tissue capacitance on whole-plant water relations. Both the sapwood and outer parenchyma tissues played an important role in regulation of internal water deficits of Cerrado trees. Relationships between minimum leaf water potential and water storage capacity across the different species suggested that daily fluctuations in water deficits were substantially reduced in species with large capacitance, contributing to the isohydric behavior of Cerrado trees. |
