摘要 为优化完善粉花山扁豆种子催芽、贮藏方法,延长其贮藏寿命及开发利用提供理论依据,试验以粉花山扁豆(Cassia javanica subsp.nodosa)种子为试材,通过正交试验设计与单因素对比探究相结合,在人工气候箱中采用托盘毛巾催芽法研究种子萌发特性,将干燥种子在室温25、4、-26℃进行贮藏,研究其贮藏特性。结果表明:粉花山扁豆种子萌发的最优处理为,浓硫酸浸种30 min,洗净后置于沸水中自然冷却至25℃,再恒温浸泡24 h,该处理方法发芽率高达100%,发芽势为76%;此外,其贮藏的最佳条件为,-26℃低温干燥环境,在贮藏180 d后,发芽率依然可以达到72.23%。 To improve and optimize the method for seeds germination and storage of Cassia javanica subsp, nodosa, further to extend the storage life and provide the theory basis for the development and utilization, C. javanica subsp, nodosa seeds were used as material, orthogonal experiment and single factor contrast were conducted. In climate cabinet, seeds were put in damp towels in trays to observe the performance of seed germination. Dry seeds were kept at 25, 4, and - 26 ℃ to investigate the storage characteristics. Results showed that the optimum method for germination was dipping seeds in concentrated sulphuric acid for 30 min, and then washing the seeds with running water, after that treating seeds in boiling bath and allowing them cool to 25 ℃, and soaking them in that constant temperature bath for 24 hours. After the treatment, the germination rate reached up to 100% and the germination viability was approximately 76%. Besides, the best method for storage was keeping dry seeds at - 26 ℃ in low moisture environment, in which the germination rate was still up to 72.23% after 180 days storage.
