Result］ The new buds and petals of I.germanica was proper to be used as explant of tissue culture, with lower browning rate compared with other positions. The well situated tissue block of explant (3 mm×3 mm×3 mm) might reduce browning rate. Adding 0.1%Vc or 0.3% active carbon in medium had obvious effect on preventing tissue browning. The exogenous hormone 2 mg/L 6-BA was easy to lead to brownness turning, and 2 mg/L Kt and 2 mg/L NAA brought less effect to tissue browning. When using disinfectants of alcohol, its dipping time of 5～10 s for explant was the best, with the minimum browning rate. The culture under full illumination condition was liable to induce brownness turning, compared with other cultured conditions, the brownness turning could be restrained effectively by using imitating artificial climate condition for culture.

结果］ 鸢尾的新生芽和花瓣较适宜作组织培养的外植体，与其他部位相比褐变率较低；外植体组织块适中（3 mm×3 mm×3 mm）可降低褐变率；在培养基中加入0.1%Vc或0.3%活性炭对防止组织褐化效果明显；外源激素2 mg/L 6-BA易引发褐变，2 mg/L Kt和2 mg/L NAA对组织褐变影响不大；使用乙醇消毒剂时，对外植体浸泡时间以5～10 s为佳，褐变率最低；全光照条件培养容易诱发褐变，采用仿人工气候条件培养较其他条件培养可有效抑制褐变的发生。

The best condition of storage and safe time limit were concluded."ZiHua" snap bean of middle maturity during storage at 9 1 shows good results.TKD treatment of 20g/m3 can effectually decrease the occurrence of decay, put off the respiration peak and restrain the decline of quality of snap bean. 6-BA treatment and GA3 treatment can delay the descent of content of Vc, chlorophyll, soluble protein and the rise of coarse fibre of snap bean. The POD activity and respiratory rate of snap beans treated by 6-BA and GAa were significantly reduced and at last reached the purpose of the delaying of spot and decay.

结果表明，中等成熟度的紫花油豆角在9±1℃下贮藏效果较好，低温可减少油豆角锈斑的发生，延缓呼吸高峰的到来，并能抑制油豆角品质的下降。20g／m~3TKD熏蒸处理油豆角可有效减少贮藏期间腐烂的发生，6-BA和GA_3处理可延缓油豆角Vc、叶绿素、可溶性蛋白质含量的下降和粗纤维含量的上升，延缓电导的增加和POD活性的上升，保持较低的膜透性、丙二醛含量，提高豆荚的PAL活性和总酚含量，从而延缓油豆角的衰老，并减少油豆角腐烂和锈斑的发生。

The biological activities of ScFv obtained from 293T cell culture fluids infected by liposome were evaluated. RESULTS: The accession number of VH and VL genes of antiricin neutralizing monoclonal antibody was DQ389248 and DQ389245. ScFv could bind with ricin specifically. Inhibition percentage of culture liquid of 293T cell without dilution and with 2 times dilution was 33.7% and 29%, respectively. ScFv could neutralize the cytotoxic effects of ricin to SP2/0 cells at the concentration of 0.01-0.005 ng/mL in a nice doseeffect relation.
