摘要/Abstract

摘要： 通过常规石蜡切片染色观察，详细研究了糜子胚发育的过程及其时间进程。糜子胚发育的全程包括3个阶段。1.原胚阶段：开花后8-10小时，合子横分裂形成2-细胞胚，再经过一系列有序的细胞分裂，在开花后1天时发育为棒状胚；开花后2天时梨形和弯曲形胚，3天时为蝌蚪形胚。2.器官分化阶段：始于蝌蚪形胚近胎座的一侧细胞液泡化，各

Abstract: The process and timing of embryo development of broomcorn millet were studied through minute observation of paraffin sections. The results indicated that the embryo development in broomcorn millet included three successive stages. (1) Stage of proembryo: Zygote divided transversely to form 2-celled
