| 摘 要： | 种子物理休眠是由种皮不透水层引起的一种休眠类型,是植物在长期系统发育进程中获得的一种适应环境变化的特性。该文简述了种子物理休眠的定义与概念;从不透水层、种皮的特殊水孔器结构以及胚的形态特异性等方面,综述了物理休眠种子的形态特征、物理休眠与综合休眠的解除方法以及物理休眠的可能解除机制;利用Angiosperm Phylogeny Group Ⅲ(APG Ⅲ)系统分析了种子物理休眠的植物在系统发育中的位置;最后提出了今后种子物理休眠有待研究的主要问题。 |

| Abstract: | Seed physical dormancy is a special type of dormancy caused by an impermeable seed coat or pericarp. It is an adaptation to environmental changes that plants acquire during long-term phylogenesis. This article introduces the concept and definition of physical dormancy and summarizes the morphological structure of physically dormant seed, which includes a water-impermeable layer of seed coat, water-gap complex and the embryo. It also summarizes the release of seed physically dormant and the mechanisms involved in the formation of openings in the seed coat. It describes the phylogenetic relationships of physically dormant seed. It also put forword the probable research point on seed physically dormant in the future. |
