摘　　要：以2020—2023年在新疆吐鲁番野生骆驼刺草种基地采集的骆驼刺种子为对象,研究骆驼刺种子在不同破除种子休眠方法、不同试验条件下的萌发特性。结果表明:骆驼刺种子在经过预处理破除休眠后发芽率提高;骆驼刺种子的最佳萌发温度为30℃;种皮摩擦处理和浓硫酸浸种预处理,对骆驼刺种子破除休眠效果最好,发芽率可达100%,且萌发时间较快;蒸馏水浸泡处理对骆驼刺种子萌发影响不明显,当浸种温度逐渐升高,浸种时间延长时,骆驼刺种子的发芽率有明显提高,在90℃蒸馏水中浸泡2h后,发芽率最高达70%。In this paper,the seeds of Alhagi sparsifolia were collected from wild Alhagi sparsifolia grass seed base in Turpan area of Xinjiang Province from 2020 to 2023,and the germination characteristics of Alhagi sparsifolia seeds under different dormancy breaking methods and dif⁃ferent experimental conditions were studied.The results showed that the germination rate of Alhagi sparsifolia seeds was improved after the seed dormancy was broken by pretreatment.The optimum germination temperature was 30℃.Seed⁃skin rubbing treatment and concentrated sulfuric acid soaking pretreatment had the best effect on breaking dormancy of Alhagi sparsifolia seeds,the germination rate was up to 100%and the germination time was faster.Distilled water soaking treatment had no obvious effect on seed germination.When the soaking temperature gradually increased and the soaking time extended,the germination rate was significantly increased.After soaking in 90℃distilled water for 2 hours,the germination rate was up to 70%.
