The results showed that the levels of endogenous polyamines in embryogenic calli were higher than those in non-embryogenic calli; the changes of endogenous polyamines in the process of somatic embryogenesis approximately showed an Mcurve during embryogeni

结果表明：龙眼胚性愈伤组织中内源多胺含量比非胚性愈伤组织高；体胚发生过程中内源多胺含量变化趋势大致呈M状，在胚性愈伤组织Ⅱ和球形胚阶段转折；内源多胺含量的变化先于形态学的变化。
