Abstract
The experiment had been conducted in the collage of Agriculture and Forestry of Mosel University. Completely Random Block Design (CRBD) was used included four intensive of ultrasonic (0, 20, 40, 60 kilohertz). and four different periods (0, 10, 20, and 30 minutes). The purpose of this experiment was to study the effect of these treatments on some of phenotypic traits and root properties in Buckthorn Ziziphus spina-Christi L. The results obtained indicated that the treatment 20 kilohertz gave significant effect on length of stem, numbers of leaves, length of root and the numbers of secondary root compare with the treatment of control. Furthermore, the treatment of 40 kilohertz gave significant effect on stem diameter, primary root and dry weight of plant root. While, the treatment of 60 kilohertz was significantly influenced on numbers of secondary root compare to the control treatment.
