Study on in vitro propagation of Alhagi sparsifolia cuttings

Using Alhagi sparsifolia cuttings as explants, the effects of different concentration of 6BA and NAA, LH, GA3 on in vitro propagation and the effects of NAA on seedling rooting were discussed. The results are as follows:1) with 0.1 mg/L NAA, reducing 6BA concentration was benefit to stem growth. On the contrary, it is benefit to differentiation of buds;2) LH is advantaged to seedling growth and differentiation of buds，MS + 0.5 mg/L 6BA + 0.1 mg/L NAA +1.5 g/L LH was the better induction medium. Propagation multiple was 6.8;3）The effect of GA3 on in vitro propagation of A. sparsifolia was not significant;4）1/2MS+ 0.1 mg/L NAA was the best medium for rooting, the rooting rate was 71.7%.
