| 摘 要： | 近年来国际上一些学者采用电子顺磁共振(electron paramagnetic resonance,EPR)、饱和迁移电子顺磁共振波谱(saturation transfer electron paramagnetic resonance spectroscopy,ST-EPRS)和极性分子探针标记等技术成功地测定了种子和花粉细胞内的分子运动(molecular mobility).依据分子运动速率确定种子和花粉的最佳贮藏条件,已成为一种新的方法,这对于植物种质资源长期保存的研究具有重要的理论和实践意义.文章对近年来花粉和种子的耐贮藏性与细胞内分子运动变化的研究进展作一综述.

| Abstract: | In recent years, it is possible to knowthe optimal storage conditions of seeds and pollenfrom the relationship between storage stability andmolecular mobility, which can be successfully de-termined by techniques of spin probe, electron para-magnetic resonance (EPR) and saturation transferelectron paramagnetic resonance spectroscopy (ST-EPRS). This is theoretically and practically impor-tant to germplasm conservation. This review focuseson the current advances in the research of molecu- lar mobility and storage stability of seed and pollen. |
