ABSTRACT = {In order to study how exogenous hormones in <i>C. lanceolata</i>
(gymnosperm) regulate somatic embryogenesis, we measured the endogenous 
phytohormones of two genotypes with different somatic embryogenesis 
efficiency and found that an increase in endogenous concentrations of IAA and 
ABA may be correlated to more efficient somatic embryogenesis. By applying 
exogenous spermidine, we found that exogenous hormones may affect somatic 
embryogenesis efficiency through affecting the endogenous phytohormone
content. Based on these results, further studies can be conducted whereby the 
concentration of exogenous hormones or the levels of endogenous 
phytohormones by molecular methods are regulated to promote somatic 
embryogenesis. Our research may benefit the long-term economic output of the 
forestry industry and lays the foundation to studying the molecular mechanism
that controls somatic embryogenesis efficiency.},
