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。

The degradation of 2, 4-dichiorophoxyacetic acid (2, 4-D) by ozonation combined with sonication (03/US) was investigated. Based on the authors' first paper about the synergistic effect of ozone and US, this paper presents intermediate products of 2, 4-D degradation. The main intermediates were 2, 4-dichiorophenol, benzopuinone, hydroquinone and organic acids, such as maleic acid and oxalic acid and soon.
