| 摘 要： | 分别用浓度为0、25、50、100、200 mg/L的GA3处理独一味幼苗,研究不同浓度的GA3对种植独一味幼苗生长发育的影响。结果表明,经100 mg/L GA3处理后,独一味幼苗长出真叶最多,株高、茎粗生长较明显,但壮苗指数和叶绿素含量均较低,而50 mg/L浓度的GA3能促进独一味幼苗的生长发育。

| Abstract: | To study the effect of different concentrations of GA3 seedling on growth and development for plant Lamiophlomis rotata(Benth) Kudo,using concentration for 0,25,50,100,200 mg/L of GA3 treatment seedling growth of Lamiophlomis rotata(Benth) Kudo.Treatment effect is the best for true leaf and plant height,but seedling index and chlorophyll content is low in 100 mg/L.The concentration of 50 mg/L GA3 promote the seedlings growth and development of Lamiophlomis rotata(Benth) Kudo. |
