| 摘 要： | 为选择高羊茅（Festuca arundinacea）种子的最佳消毒处理方法，选用6种常用种子消毒处理方法：0.1% HgCl2浸泡10 min、10% H2O2浸泡20 min、0.5% KMnO4浸泡10 min、75% C2H5OH浸泡 5 min、2.0% NaClO浸泡20 min、0.16% HCHO浸泡30 min进行消毒处理，对其消毒效果、种子萌发及幼苗的影响进行测定。结果表明：10% H2O2浸泡20 min和0.5% KMnO4浸泡10 min的消毒效果较好，对种子萌发和幼苗生长均没有负面影响，可以作为高羊茅种子理想的消毒方法优先选用；0.1% HgCl2浸泡10 min和2.0%NaClO浸泡20 min的消毒效果虽好，对种子发芽率没有影响但对种子萌发速度和幼苗生长有一定的影响，慎重选用；75% C2H5OH浸泡5 min和0.16% HCHO浸泡30 min的消毒效果不佳，对幼苗的生长也有影响，且0.16% HCHO处理对种子的伤害较大，不宜选用。

| Abstract: | The aim of the study was to find out the most effective disinfection methods of tall fescue (Festuca arundinacea) seeds. The effects of 6 disinfection treatments (0.1% HgCl2 soaking 10 min, 10% H2O2 soaking 20 min, 0.5% KMnO4 soaking 10 min, 75% C2H5OH soaking 5 min, 2.0% NaClO soaking 20 min, 0.16% HCHO soaking 30 min) on disinfection effectiveness, seed germination and seedling growth were assessed in the experiment. Results showed that 0.5% KMnO4 and 10% H2O2 treatments greatly reduced seed infection, and had no obvious negative effects on seed germination and seedling growth. They were recommended as priorities to disinfect tall fescue seed. 0.1% HgCl2 and 2.0% NaClO treatments could effectively reduce seed infection, but had negative effects on seedling growth. 75% C2H5OH and 0.16% HCHO treatments showed poor disinfecting results and had negative effect on seedling growth. |
