光质-照度对叶下珠种子萌发的影响

In this study,we explored the different light qualities and intensities treatments on the influence of Phyllanthus urinaria L.'s seed germination, hoping to provide certain scientific basis for raising seedling technology and the artificial cultivation of Phyllanthus urinaria L..Results indicate that:The seeds of Phyllanthus urinaria L. exhibit photosensitive properties, germinating under the condition of light can significantly improve the germination rate;Different treatments of light qualities (red, yellow, green, blue, and purple)stimulate seeds' germination;with the increasing of red light intensity, the seeds' germination rate is higher;Green, blue, violet light with the 1000 lx light intensity are the most suitable for germination;Yellow and white light with low light intensity have a good germination rate.Yellow, green with high light intensity reduce uniformity of the seeds' germination. In this experiment,we obtained the optimal light conditions under different light qualities, and the optimal light qualities under different light intensities of the seeds' germination of Phyllanthus urinaria L., having a guiding role to raise seedling and artificial cultivation.
