In this study,Sea buckthorn branches were cut into 5 segments sequentially from the top down. Each one was 3cm long. The segments were treated respectively with five kinds of rooting hormone(ABT1,ABT2,GGR6,GGR7,and sodium nitroprusside+ABT1),and three seedling methods were used with different cutting mediums such as soil,water and sand.The results show that rooting rates on soil water,and sand mediums were 49%,65%,and 80% respectively. The highest rooting rates was the segments treated by GGR6 with the rooting rate of 55% in soil,83.5% in water and 96.8% in sand medium The third segment had the highest rooting rate of all five segments and the rates in each medium(soil,water and sand) were: 67.36%,73.75%,and 84.33%. At the same period, the average lengths of the roots that grew from three different mediuma(soil,water and,sand) were: 1.9cm,3.6cm,and 6.45cm respectively; the numbers of average roots were: 2.1,2.75,and 4.45; and average diameter of the roots were: 2.35mm,2.6mm,and 3.25mm. The study provides a theoretical basis for a large-scale industrial cultivation of seabuckthorn.
