从枣胚败育原因、胚培养影响因素、胚培养成苗途径等方面对枣胚培养研究进行了综述。枣胚败育主要由授粉受精不良、胚和胚乳发育不良、激素水平异常等引起;影响胚培养的因素主要有胚龄、培养基和环境条件;胚培养成苗途径主要有维持胚性生长的直接成苗、脱分化成愈伤组织的器官发生、体细胞胚的发生等3种。今后还需深入研究枣胚败育的机理、完善枣幼胚离体培养条件与方法,加快推进枣育种技术创新进程。
The research on jujube embryo culture from the reasons of abortion of jujube embryo, the influencing factors of embryo culture and the path of embryo culture and seedling were reviewed. Jujube abortion abortion is mainly caused by poor pollination and fertilization, poor embryo and endosperm development, and abnormal hormone levels. The main factors influencing embryo culture are embryo age, culture medium and environmental conditions. The main pathways of embryo culture are embryo growth Direct into seedlings, dedifferentiation into callus organs, the occurrence of somatic embryo 3 kinds. In the future, the mechanism of abortion of jujube embryo should be further studied, the conditions and methods of in vitro culture of jujube embryo should be perfected, and the innovation of jujube breeding technology should be accelerated.
