The invention relates to a method for promoting germination of peanuts under low-temperature stress, which comprises the following steps: soaking peanut seeds for 6-24 hours by adopting a 12-oxo plant dienoic acid solution with the concentration of 50-350 mu g/L, sowing the soaked seeds in a low-temperature stress environment, and germinating to obtain seedlings. According to the method, OPDA is adopted to soak peanut seeds, germination of the peanut seeds under the low-temperature condition is promoted, the emergence rate is increased, the method is simple and easy to implement, the effect is obvious, the application potential is large, damage of low temperature to peanut germination and seedling stage is effectively relieved, and the cold resistance of peanuts is enhanced. 本发明涉及一种促进花生低温胁迫下发芽的方法，包括以下步骤：采用浓度为50~350μg/L的12-氧代植物二烯酸溶液浸泡花生种子6-24小时，将浸泡后的种子播种于低温胁迫环境中，萌发得到种苗。该方法采用OPDA浸泡花生种子，促进其在低温条件下萌发，提高出苗率，该办法简单易行，效果明显，应用潜力大，有效缓解低温对于花生萌发和苗期的伤害，并且增强花生的耐冷性。
