摘　　要：为探究广西小黄姜试管姜的诱导条件,采用不同浓度的蔗糖、多效唑和钾营养对广西小黄姜试管苗进行诱导研究,比较分析了诱导的试管姜块大小、直径和植株生长情况。结果表明:广西小黄姜对蔗糖的耐受性较差,70 g/L浓度条件下出现了生长受抑制的现象,最佳的诱导浓度为50 g/L;在低糖浓度条件下添加多效唑并不能诱导广西小黄姜产生姜块,在多效唑添加浓度为6 mg/L时,试管苗的生长开始受到抑制;添加低浓度钾对广西小黄姜试管苗生长具有促进作用,但不产生姜块;添加高浓度的钾可诱导小黄姜试管苗产生姜块,但是生长会受到抑制。优组试验表明,最佳的蔗糖浓度为50 g/L、多效唑浓度为2mg/L、磷酸二氢钾浓度为60mmol/L,该组合诱导的试管姜植株粗壮,叶色翠绿,根系生长良好,诱导出的姜块大,有实际应用价值。In order to explore the inducing conditions of tube-ginger of small yellow ginger in Guangxi,different concentrations of sucrose,paclobutrazol and potassium nutrition were used to induce tube-seedlings of small yellow ginger in Guangxi,and the size,diameter and plant growth of induced tube-ginger were compared and analyzed.The results showed that the tolerance of small yellow ginger to sucrose was poor,and the growth of small yellow ginger was inhibited at the concentration of 70 g/L,and the best induction concentration was 50 g/L.Under the condition of low sugar concentration,addition of paclobutrazol could not induce the production of ginger blocks,and the growth of plantlets in vitro was inhibited when paclobutrazol was added at 6 mg/L.Adding low concentration potassium could promote the growth of tube-seedlings of small yellow ginger in Guangxi,but did not produce ginger blocks.Adding high concentration of potassium could induce small yellow ginger plantlets to produce ginger lumps,but the growth would be inhibited.The optimum sucrose concentration was 50 g/L,paclobutrazol concentration was 2 mg/L,potassium dihydrogen phosphate concentration was 60 mmol/L.These combination induced stout ginger plants,green leaves,good root growth and large ginger blocks,which had practical application value.
