摘  要:
以太行菊(Opisthopappus taihangensis)作为试材,进行了细胞悬浮培养的初步探讨.结果表明,试管苗茎段诱导愈伤组织最适培养基配方为MS+6-BA2.0 mg·L-1+NAA0.5 mg·L-1+2,4-D 1.0 mg·L-1,诱导出的愈伤组织生长迅速,且排列紧密质地松软适合进行细胞悬浮培养.将获得的愈伤组织在液体培养基MS+6-BA 2.0mg·L-1+2,4-D 0.5 mg·L-1中震荡培养,建立细胞悬浮体系.悬浮细胞的生长曲线呈抛物线型,初期增长缓慢,4~6 d进入对数增长期,6 d以后由于培养基中营养物质的消耗和pH值的下降,细胞生长迅速下降.

摘  要:
This paper has done the preliminary research on cell suspension culture of Opisthopappus taihangensis.The results show that the most suitable medium for callus induction using stem as its explant is MS+6-BA 2.0 mg·L-1+NAA 0.5 mg·L-1+2,4-D 1.0 mg·L-1.The callus grows fast and unconsolidated which is appropriate for cell suspension culture.To establish cell suspension culture,put the callus in liquid medium MS+6-BA 2.0 mg·L-1+2,4-D 0.5 mg·L-1 and shake.The growth curve of suspension cells is of a parabola type.At the beginning of the culture,cells increased slowly,and during 4 to 6 days,they reached logarithmic growth.6 days later,as a result of the large consumption of nutrients in medium and the pH value fallen off,the trend of increasing went down.
