摘　　要：硬实是种子休眠类型之一,在豆科作物中最为常见。种皮缺乏透性是硬实大豆形成的主要原因。种子硬实的影响因素包括遗传因素、大豆生长后期的环境条件以及贮藏条件等。硬实的处理方法机械划破种皮、温度处理、干湿交错处理和化学处理等。在种质保存过程中还可对种子硬实特性加以利用,发挥坚硬种皮的保水作用。Hard seed is one type of seed dormancy, especially in leguminous species. Soybean hard seed is mainly caused by impermeability to water and gas to the seed coat. Genetic factors, environmental condition in the later period of the soybean growth and storage condition can affect hard seed state. The methods for breaking hard seed include mechanical scarification, low and high temperature, hydration-dehydration, chemical treatments etc. Impermeability of hard seed coat is beneficial to sustain higher seed vigor for a long time and has especially important significance to preserve germplasm.
