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。
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.
