树木种子的休眠性状是普遍存在的,它的类型多样而复杂。本文收集了50科150多种植物休眠性种子的研究材料,分析了各类种子的休眠性状和破除方法,进而从代谢水平上阐述了种子休眠解除的作用机理,其中包括内源激素的相互作用,以及光敏素与需光萌发和磷酸戊糖途径在解休眠中的作用。 The dormancy traits of tree seeds are ubiquitous, and their types are diverse and complex. In this paper, the research materials of more than 150 kinds of plant dormancy seeds in 50 families were collected, and the dormancy and disintegration methods of all kinds of seeds were analyzed. Then the mechanism of seed dormancy release was expounded from the level of metabolism, including the interaction of endogenous hormones , And the role of phototransmitters in photoperiod and pentosephosphate pathway in solution to dormancy.
