研究前提：凤仙花是一种常见的园林花卉，适应能力强，栽培历史悠久。但对其生理抗性机制的研究较少。本试验从经历航天诱变和12年栽培育种的凤仙花中选择。因此，在抗旱性方面优于未诱变凤仙花，在生理上也表现出与正常凤仙花的巨大差异，这引起了学者们对其深层原因的研究。方法：以凤仙花为参照，用不同浓度的PEG-6000溶液处理的诱变凤仙花种子，测定干旱下游地区凤仙花种子的发芽率、相对酶活性及SoS2基因和RD29b基因的表达差异。关键结果：模拟干旱胁迫下，诱变凤仙花的发芽率与正常凤仙花无明显差异。但通过测定根分蘖数和根长、相对酶活性、MDA、SoS2基因和RD29b基因在干旱下游地区的表达差异，验证了诱变凤仙花比正常凤仙花具有更大的优势，可以进一步培育成为抗旱性品种。结论：本试验为正突变，诱变凤仙花通过辐射诱变提高抗旱性。这样得到的凤仙花在颜色和形状上都更加美观，在园林绿化中有较高的应用价值。

英文摘要：
  Premise of the Study: Impatiens is a commonly seen garden flower, renowned for its strong adaptability and long history of cultivation. However, seldom has any research touched on its physiological resistance mechanism. In this experiment, the impatiens is selected from those which experienced aerospace mutation and thereafter 12 years of cultivation and breeding. Therefore, it is superior to the non-mutagenized impatiens in terms of drought resistance and demonstrates tremendous differences from the normal impatiens in physiology, which intrigues scholars to search for the underlying reasons . Methods: By reference to Impatiens balsamina L,this experiment uses mutagenized impatiens seeds, processed by PEG-6000 in different solution concentration, to measure the germination rate of impatiens, its relative enzymatic activity and expression differences between gene SoS2 and gene RD29b in the drought lower reaches. Key results: Under simulated drought stress, there is no distinct difference between the mutagenized impatiens and the normal impatiens in terms of germination rate. But by measuring the root tillers and the length, the relative enzymatic activity, MDA, and the expression differences between gene SoS2 and gene RD29b in the drought lower reaches, it is verified that the mutagenized impatiens has more advantages than the normal impatiens, and it Can further cultivate become drought resistance varieties impatiens. Conclusions: In this experiment,which is a positive mutation, the mutagenized impatiens improves drought resistance through radiative mutation. The so obtained impatiens is more pleasing in sight in terms of color and shape and has higher application value in garden virescence.
