摘要：对唐古特白刺硬枝扦插繁殖技术进行了研究,结果表明,5种激素(ABT、NAA、IAA、IBA、NAA+IBA)和4种浓度(100,200,400,600 mg/L)的不同处理能够提高白刺的成活率。以NAA 400 mg/L、IBA 100 mg/L和NAA+IBA 100 mg/L为最优,分别是对照的269%,254%和239%。白刺硬枝扦插经激素处理后,可提高苗木的生长指标。在激素与浓度配比中,IBA 400 mg/L对根长和根数的促进作用明显;NAA+IBA 200 mg/L对株高和枝条生长的增长具有一定的作用,ABT 400 mg/L能够加速地径的生长。从综合指标看,以IBA 100 mg/Lg处理最适宜。
Experiment on hardwood cuttage propagation of Nitraria tangutorum was carried out. The results showed that ： The ratio combinations of five kinds of hormone （ ABT, NAA, IAA, IBAand NAA ＋ IBA） and four levels of hormone concentra- tion （ I00,200,400 and 600 mg/L） could improve the survival rate of N. tangutorum. The optimal treatment for improving survival rate ofN. tangutorum was with NAA 400 mg/L （269%）, followed by IBA 100 mg/L （254%） and NAA ＋ IBA 100 mg/L （239%）. The hormone treatment significantly enhanced the growth index of seedlings after hardwood cuttings of N. tangutorum. Among the treatments with different hormone ratio and concentration, the treatment IBA 400 mg,/L played obvious role in increasing the root length and root number of hardwood cutting seedlings, the treatment NAA ＋ IBA 200 mg/L promoted the height and branches, and the treatment ABT 400 mg/L exerted a significant effect on the growth of ground diameter. In addition, the biomass of seedlings was significantly increased after hormone treatment. From the point of com- prehensive index, IBA 100 mg,/L is the optimum treatment combinations.
