| 摘 要： | 以灯盏花组培不定芽为材料，研究探讨了不同光照强度对灯盏花无糖组培苗生长发育的影响。结果表明：在一定光照强度、一定CO2浓度范围内，光照强度对灯盏花无糖组培苗生根率、干物质含量的积累具有重要的作用，在适宜的培养条件下，光照强度越强，生根率也越高；强光照对灯盏花无糖组培苗干物质含量的积累明显增强。

| Abstract: | In this research,adventitious bud of Erigeron breviscapus were used as materials.And studied the effect of different light intensity on development of plantlet in sugar-free tissue culture of Erigeron breviscapus.Results showed that under the conditions of stated light intensity and CO2 concentration,the light intensity was an important factor for plantlet in sugar-free tissue culture of Erigeron breviscapus to root and accumulate dry substance.Under feasible conditions,with the improvement of light intensity,the rooting rate and dry substance content increased obviously. |

| Keywords: | Erigeron breviscapus light intensity sugar-free tissue culture rooting rate dry substance content |
