摘要
以不同类型野生山楂种子为试材,观察了冷藏、常温处理对野生山楂种子萌发情况的影响,以期探讨山楂种子休眠的原因,寻找破除种子休眠的处理方法。结果表明:山楂种子的休眠性与种子种仁无关,与种壳有关,浓硫酸处理山楂休眠种子的最佳时间为50 min。
Through the investigation for different types of wild hawthorn seed physical proterties as well as observation of the influence of the normal-temperature and refrigerated treatment of wild Hawthorn seed germination,discussed the reason of seed dormancy of the wild Chinese hawthorn.The results showed that the dormancy of Hawthorn seed had not related to seed kernel,but related to the existence of seed shell.In the process of acid-etching treatment of the hawthorn seed,the best time was 50 minutes.
