探讨适宜浓度冠菌素(COR)浸种提高花生幼苗抗旱性的作用效果，为COR在生产上应用提供依据。在正常水分和25%聚乙二醇(PEG)模拟干旱条件下，研究不同浓度COR浸种对花生种子萌发和幼苗生长的影响。模拟干旱严重影响种子发芽和幼苗生长。0.0001~1μmol/L的COR浸种可不同程度补偿干旱胁迫对种子发芽和幼苗生长的抑制作用，以0.01μmol/L COR处理的效果最好，发芽势、发芽率、发芽指数、活力指数、幼苗生长和干物质积累均明显提高，根系生长接近对照水平，从而使根冠比提高幅度更大。COR可明显缓解干旱对花生幼苗生长的影响，0.01μmol/L的COR浸种可作为提高花生幼苗抗旱性的技术措施。

The aim was to study the effect of suitable concentration coronatine (COR) soaking to improve the drought resistance of peanut seedlings and provide the basis for the application of COR in production. Under normal water and simulated drought with 25%polyethylene glycol (PEG) conditions, the effects of presoaking with different concentrations of coronatine (COR) on peanut seed germination and seedling growth were studied. Simulated drought had serious effects on seed germination and seedling growth. Presoaking with 0.0001-1 μmol/L COR compensated the inhibitory effect on seed germination and seedling growth in different degrees, the 0.01 μmol/L COR showed the best effect. The germination potential, germination rate, germination index and vigor index, shoot growth and dry matter accumulation of seedlings were significantly improved. The root growth was close to the control level, so that the root to shoot ratio was improved more significantly. COR could obviously alleviate the effects of drought on the growth of peanut seedlings, 0.01 μmol/L COR soaking could be used as the technical measures to improve the drought resistance of peanut seedlings.
