Abstract In order to study how exogenous hormones in C. lanceolata
(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… More >
