摘　　要：为探明不同储藏方式对花生萌发的影响,以高油酸花生品种豫花37号和开农1715、高油花生品种远杂9102和豫花9326为试验材料,选用不同储藏温度和包装方式,研究不同储藏方式对种子发芽能力、氧化程度、内源激素含量的影响。结果表明,花生类型、储藏温度和包装方式均对花生种子的耐储性有显著影响,较高的油酸含量、低温和自封袋储藏条件,可有效减缓种子氧化进程,维持种子内源激素含量在相对较高水平,从而保证种子活力及发芽能力。相较常温储藏,低温储藏可较好地保持种子活力,低温储藏39个月后,四品种平均发芽率在82%以上,而常温储藏四品种平均发芽率不足32%;包装方式以自封袋优于塑料袋优于网袋,低温储藏39月后,自封袋、塑料袋、网袋发芽率分别保持在85%、83%、80%左右,常温储藏39月后,自封袋、塑料袋、网袋发芽率仅38%、33%、24%左右;高油酸花生品种比普通花生品种更耐储藏,储藏39个月后,两高油酸品种的平均发芽率可保持75%以上,而两普通花生品种的平均发芽率则不足40%。就花生类型而言,高油酸花生的耐储性要优于普通花生,且如果降低环境温度,增加包装的密封程度,还可在一定程度上提高种子的储藏后的活性。In order to verify the effects of different storage methods on the germination of peanuts,the high oleic acid peanut variety Yuhua 37 and Kainong 1715,the high oil peanut variety Yuanza 9102 and Yuhua 9326 were used as test materials,and different storage temperatures and packaging methods were selected to study the effects of different storage methods on seed germination ability,oxidation degree and endogenous hormone content.The results showed that peanut type,storage temperature and packaging method had significant effects on the storage resistance of peanut seeds.Higher oleic acid content,low temperature and storage conditions in ziplock bags could effectively slow down the oxidation process and maintain the content of endogenous hormones in seeds at a relatively high level,thus ensuring seed vigor and germination ability.Compared with normal temperature storage,low temperature storage could better maintain the vitality of seeds.After 39 months of low temperature storage,the average germination rate of the four varieties was above 82%,while the average germination rate of the four varieties stored at normal temperature was less than 32%.The packaging method of ziplock bags was better than plastic bags and mesh bags.After 39 months of low temperature storage,the germination rates of ziplock bags,plastic bags,and mesh bags were maintained at about 85%,83%,and 80%,respectively.After 39 months of normal temperature storage,the germination rates of ziplock bags,plastic bags,and mesh bags were maintained at about 38%,33%,and 24%,respectively.The peanut varieties with high oleic acid were more resistant to storage.After 39 months’storage,the average germination rate of two high oleic acid varieties could be maintained above 75%,but the average germination rate of two normal peanut varieties was less than 40%.As far as peanut types are concerned,the storage resistance of high oleic acid peanuts is better than that of ordinary peanuts,and reducing the ambient temperature and increasing the sealing degree of the pack
