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。

Beijing Institute of Technology, Beijing 100081,ChinaIn order to get the high output power, a RF excited diffusively cooled all-metal slab waveguide CO2 laser was reported, in which gas discharge region was constructed by two aluminum side walls and aluminum electrodes. The region dimension was 2 mm height×20 mm width×386 mm length, and the gas composition was CO2:N2:He:Xe=1:1:3:0.26. This technique replaced the old ceramic and metal sandwich waveguide technique.The optimum out power 127 W was achieved from the RF excited diffusively cooled all-metal slab waveguide CO2 laser with the longitudinal voltage uniformity distribution technique and scaling area technique. The electro-optic conversion efficiency was about 14%.
