Abstract: The seeds of Oxytenanthera abyssinica from Ethiopian,Africa were soaked with paclobutrazol at 3 concentrations of 50,100 and 200 mg / L for 24 h. The seeds germination,seedling growth,physiological change and anatomical characters of Oxytenanthera abyssinica were studied. The results showed that paclobutrazol soaking had no significant effect on the germination potential and germination rate,but it could restrain plantule length strikingly,dwarf seedlings,and increase the chlorophyll content. In addition,it enlavged the epidermis cells,bulliform cells and thickened the epidermis hair of leaves. After the seeds of Oxytenanthera abyssinica were soaked with paclobutrazol for 7 days,the plantule length was 0. 54 0. 42 cm and 30 days later,the average seedling height was 4. 92 2. 36 cm,the inhibition ratio of which was 52. 42% 77. 2%. From comprehensive analysis,it may be concluded that 50 mg / L or 100 mg / L could be used in practice of production.
