| 摘 要： | 为了解决四倍体刺槐硬枝扦插成活率低的问题,利用冬季沙藏结合生长调节物质处理和倒放催根的方法对四倍体刺槐进行硬枝扦插试验。结果表明:经冬季沙藏,结合沙藏前和扦插时的2次生长调节物质处理,插穗扦插成活率最高,达66.67%;在IBA、NAA和ABT三种生长调节剂的处理试验中,500 mg.kg-1的ABT处理插穗扦插成活率最好,成活率达71.11%;插穗倒放沙藏明显提高了扦插成活率;插穗经温室沙藏处理比室外沙藏处理成活率高。 |

| Abstract: | To enhance the rooting rate of tetraploid Robinia pseudoacacia by hardwood stem cutting, cuttage of hardwood treated by low temperature sand storage with plant growth tegulator and upended were researched. The results showed that cuttage of hardwood treated by sand storage in winter and two-step hormone treatment was the best treatment, the survival rate reach 66.67 percent or more, 500 mg·kg^-1 ABT was the best hormone condition of treatment in three density of IBA, NAA and ABT, the survival rate of hardwood cuttage was appreciably increased by storaged in greenhouse and upended in sand. |
