Abstract: The objective of this study is to determine the spatial existence and anatomical distribution of immature living vessels in the young developing plant stems, and to determine the effect of living vessels on the pattern and direction of movement in the developing xylem networks. The used tests were; the suction-coloration test and the single-vessel dye injection. These tests were applied on the Albezia lophanta. All experiments were conducted in the scientific research center for arid regions (CRSTRA)-Touggourt. The results showed that living vessels occurred along the xylem network of young shoots. These vessels differentiated as successive layers and distributed between the vascular cambium and mature dead vessels. Concerning the single-vessel dye injection test, it is observed that water moved in the lateral direction through the lateral contacts, and this clearly demonstrate the effect of living vessels on the hydraulic architecture and movement patterns in the developing xylem networks.
