Dynamics of sap flux densities measured by the multi-point HFD sensors in the control lime tree (Tilia, South) and in the sample maple tree at different sides and heights (East_st and West_st – at breast height and East_br and West_br – just below the crown of the main branch) during the first severing experiment. Numbers denote the depth of the measuring points below the cambium (mm). Vertical lines mark the two moments of severing the lateral branch. Data with a 1-min recording interval are presented.
