It was considered that how the plant growth regulation by light quality to develop and control the growth of seedlings. At same time, it was carried out that the some genes expression concerned with light condition during the growth stage of seedling, were analyzed by comprehensive analysis methods. In the case of petunia, as the results of a comprehensive gene analysis, some genes concerned with floral development under red and blue light condition was find out. From those results, we tried the combination treatment of light quality treatment and some phyto-hormone applications, and showed the possibility of a new plant growth regulation method by light quality during the raising the seedlings of horticultural crops

考虑如何通过光质对植物生长的调控来发育和控制幼苗的生长。同时，采用综合分析方法对幼苗生长阶段一些与光照条件有关的基因表达进行了分析。以矮牵牛为例，综合基因分析的结果，发现了一些与红光和蓝光条件下花发育有关的基因。根据这些结果，我们尝试了光质处理和一些植物激素施用的组合处理，并展示了在园艺作物育苗过程中通过光质调节植物生长的新方法的可能性。
