栎属植物体细胞胚胎发生研究现状

总结了影响栎属植物体细胞胚胎发生的主要可控因素及体细胞胚的遗传变异，组织学研究现状。目前，已能从成年组织上诱导出体细胞胚，但诱导率较低。重复性体胚发生系统已被认为是一种可资利用的繁殖途径，倍受关注。应用DNA分子标记分析表明：体胚细胞系内存在遗传变异。成熟和较低的萌发率是这一技术广泛应用的瓶颈。

Recently research situation of somatic embryogenesis in oak (Quercus spp.)

This paper summarizes the research progress of the factors involved in controlling the process of oak somatic embryogenesis,as well as the genetic variation and histology at present. Somatic embryos from mature explants have been obtained,but the frequencies are low. The repetitive embryogenesis system is regarded as a useful propagation pathway and arouses general concern. Somaclonal variation was detected with DNA molecular markers. Maturation and low germination frequencies are the main bottlenecks for a broader use of this technique in Quercus spp.
