植物种子的皱缩现象是种子劣化的一种形态.皱缩种子的产生,不仅严重影响种子的外观品质,还会使种子活力和发芽能力显著下降.目前,皱缩种子的产生已经成为制约杂交大豆、杂交小麦和甜玉米等作物大规模制种的难题之一.然而,在植物皱缩种子的形成机理及改良方法方面,虽然有一些研究,但缺乏系统性.本文对植物种子皱缩的发现和定义、评价方法、影响因素、形成机理和改良方法等进行系统归纳和总结,以期为科研人员研究、解决这一问题提供参考和借鉴.“,”Shrinking seeds is a form of seeds deterioration in plants. The appearance of shrinking seeds not only influence exterior quality of seeds, but also lower seed vigor and germination ability. At present, shrinking seeds has already become constraints of large-scale of seeds production in hybrid soybean, hybrid wheat and sweat corn. There are some studies on formation mechanism and improvement methods of shrinking seeds, however, it is scatted and lack of systematic summary. The discovery and definition of shrinking seeds, as well as its evaluation methods, influence factor, formation mechanism and improvement methods were summarized in the paper to provide reference to help researchers to understand and resolve this problem.
