Abstract: Ahstract The stem-segments of S.lineare were cultured under the light of different wavelength with similar irradiance. By comparing the morphogcnesis and physiobiochemistry of the test tube shoot, the results showed that in some cxtent, the shoot number, biomass, green pigment and the content of carbohy- drates, proteins, total nucleic acids,. RNA and DNA were influenced by the light of different wavelength. The biomass of shoot under blue light is the highest, the green pigment under white light is the highest. Red light is good for sugar synthesis and blue light is good for all others.

Key words: Sedum lineare

摘要： 植物的正常个体发育过程中都存在着一个受光控制的光形态建成过程。光作为植物组织培养中的一个调控因子，已有报道门，引。本实验通过对佛甲草的不同波长的光处理，比较其形态发生及生理生化指标。佛甲草为一种药用植物[3] 本实验为建立佛甲草茎段培养的理想诱导模式提供了初步的资料。
