| 摘 要： | 以芦笋的茎尖为外植体，分别从糖、无机盐、激素等方面研究了在离体条件下影响芦笋生根的因素。结果分析表明：1/2 MS、20 g·L-1的糖有利于生根；10 g·L-1糖、1/4 MS培养基上预处理12 d后，生根率可达到100%，根的质量明显优于生长在含有激素培养基上的根；激素预处理并不能提高生根率。因此，低盐及低糖预处理是提高芦笋生根率的一种比较好的方法。

| Abstract: | Using Asparagua officinalis stem shot as explant, the paper discussed the factors that affected the rooting in vitro. The concentration of sucrose, abiosalt and plant growth regulator were studied. The result indicated that 1/2MS and 20g·L-1 sucrose promoted rooting;Rooting rate arrived at 100% when it was pretreated in the twelfth with 1/4MS and 20 g·L-1 sucrose. Its quality of root excelled the root in the medium with hormone；pretreatment of hormone couldn’t enhance rooting rate.Therefore,low salt or low sucrose pretreatment was a kind of good way for advancing rate of rooting in Asparagua officinalis. |
