Hydraulic connectivity from roots to branches depicted through sap flow: analysis on a Quercus suber tree

Popis výsledku v původním jazyce

The hydraulic architecture of a mature Quercus suber tree was evaluated through sap flow responses upon branch severing. The tree stem divided at the top into four large branches oriented NE, NW, SE and SW. Half of the branches (NW and SE) were cut one month earlier than the other ones (NE and SW). Sap flow responses to branch severing were recorded in branches, stem and roots with a high time resolution. Sap flow was monitored by the heat field deformation method (HFD). Single-point and multi-point sensors were used. Results showed that sectoriality was high in branches, stem and tap root, since sap flow predominantly responded to branch cuttings in the same orientation, in all xylem layers. All the other roots showed integrated connections to the crown: sap flow responded to all branch cuttings irrespective of orientation. This integrative feature of average sap flow in large roots resulted from preferential connections of outer xylem to the same side branch and of the inner xylem to
