摘　　要：概述了种子休眠类型及其破除方法的研究情况。种子休眠根据不同的标准可以分成不同的类型,影响种子休眠的因素是复杂的,通常从种子结构,抑制物和激素作用,光敏素的作用,种胚发育程度等方面考虑。分子遗传学研究表明,种子休眠是由多基因控制的数量遗传性状,需要根据休眠机理采用相应的物理方法、化学方法或者综合方法打破种子休眠。The researches on the seed dormancy types and the breaking methods were summarized. According to various criteria, seed dormancy could he classified into various types. The influencing factors of seed dormancy were complicated, including seed structure, the effect of hormone and inhibitor, the effect of phytochrome, and the development of embryo and so on. The molecular genetics researches indicated that seed dormancy was generally quantitative genetic trait influenced by a large number of genes. The seed dormancy could be broken by using the physical methods, chemical methods or composite ways according to the dormancy mechanism.
