1·Normal embryoids could fully develop and mature through the process that was analogous to the differentiation of zygotic embryo.
正常胚状体可通过类似合子胚的分化或不规则发育过程而成熟。
2·A sharp demarcation of adventive embryos from zygotic embryos cannot be drawn.
不定胚与合子胚之间不能划分出明显的界限。
3·As a result, an in vitro zygotic embryogenesis system was build up, in which single tobacco zygotes could develop into fertile plants via embryogenesis or organogenesis under optimal condition.
通过培养条件的优化，使烟草合子在体外通过器官发生途径与胚胎发生途径两种方式再生可育植株，从而创建了烟草合子的体外胚胎发生系统。
4·Its functions are like a zygotic embryo in giving rise to a new plant.
其功能象能产生一株新植物的合子胚。
