1、毛脉酸模无菌苗的制备及下胚轴愈伤组织诱导的研究?98?中医药信息InformationonTraditionalChineseMedicine2012年第29卷第2期Vo1.29,No.2,2012毛脉酸模无菌苗的制备及下胚轴愈伤组织诱导的研究谢彦梅,许岩,常丰华,沈剑,王振月(黑龙江中医药大学,黑龙江哈尔滨150040)摘要:目的:建立制备毛脉酸模无菌苗及下胚轴愈伤组织诱导方法.方法:通过摩擦种皮,种子浸泡时间,消毒次数,消毒剂种类,消毒时间以及种子贮存时间等因素研究对种子发芽的影响,探讨建立无茵苗培养体系的最佳方法;以获得的无菌苗的下胚轴为外植体,通过在Ms基本培养基中
2、附加6一BA和2,4一D两种激素不同配比筛选诱导愈伤组织的最优培养基配方.结果:制备毛脉酸模无菌苗的方法为:挑选粒大饱满的新种子,120目砂纸摩擦种皮,蒸馏水浸泡24h,75%酒精中浸2min,无菌水冲洗3次,10%NaC10溶液处理10min,无菌水冲洗5次,将其放置在有两层湿润的无菌滤纸的培养皿中10h,再进行第2次消毒,10%NaC10溶液处理8min,无菌水冲洗5次,在无激素的MS培养基中培养即可获得大量无菌苗;下胚轴愈伤组织诱导的最优培养基为MS+3.0rag/L6一BA+1.7mg/L2,4一D.结论:建立了毛脉酸模无菌苗培养体系,得到下胚轴愈伤组织诱导的最优培
