The research on the tissue culture and cell suspension culture showed that thesuitable culture medium for inducing bud was MS supplemented with 1.5mg/L 6-BAand 0.1mg/L NAA, and for the generation-continuing multiplication was MSsupplemented with 1.5mg/L 6-BA and 0.2mg/L NAA. The rooting medium was1/2MS supplemented with 0.5mg/L IBA and the rooting rate was 45.0%. Plantletsurvival after transfer to sand was 52.5%.The induction rate of calli was66.7%~86.6% and the optimum medium was MS medium with 0.5mg/L 6-BA and2.0mg/L 2,4-D. The calli became smallest partical size, friable and had gooddispersion ability after 3 times successive transfer culture, the optimum medium wasMS medium with 0.2mg/L 6-BA and 2.0mg/L 2,4-D. Culturing these particles on sixkinds of MS liquid media with different hormone contents, the optimum medium wasselected basing on he change of the density of single-cell, the density of cellaggrefate and the mass of cell.

对蒜头果进行的组织培养与细胞悬浮培养研究结果表明:MS+6-BA1.5mg/L+NAA0.1mg/L+蔗糖3%激素组合能够较好地诱导芽的初始分化和增殖,适宜的芽苗继代增殖培养基为MS+6-BA1.5mg/L+NAA0.2mg/L+蔗糖3%;采用1/2MS+IBA0.5mg/L+蔗糖3%为生根培养基,生根率为45.0%;移栽到河沙的生根苗成活率为52.5%;愈伤组织诱导率为66.7%~86.6%,其中以MS+6-BA0.5mg/L+2,4-D2.0mg/L+蔗糖3%的培养基最佳,其诱导出的愈伤组织具有较强的增殖能力和较好的脆散结构,最佳继代培养基为MS+6-BA0.2mg/L+2,4-D2.0mg/L+蔗糖3%,且培养基中的6-BA与2,4-D浓度的比值越小,愈伤组织生长越快,结构越脆散,增殖率越高;将继代后的愈伤组织转入6种含不同激素浓度组合的MS液体培养基中进行振荡培养,在综合分析各培养基的单细胞密度,细胞团块密度,细胞生物量增长率等指标后,初步筛选出MS+6-BA0.2mg/L+2,4-D2.0mg/L培养基为较好的液体培养基。
