摘要： Cotyledons of Watermelon (Citrullus lanatus) were cultured in vitro on medium deprived of plant growth regulators. Inbred lines varying in their embryogenic capacity were studied after 90 days in culture media. Endogenous levels of indole-3-acetic acid (IAA), abscisic acid (ABA) and trans-zeatin riboside (ZR) were analyzed in embryogenic cotyledons. Significant differences were observed in total ABA, IAA, ZR, concentrations of the embryogenic cotyledons. On the contrary, lower Z and ACC contents and also a reduced balance between Z and IAA levels were related with the embryogenic capacity of the cotyledons. These results suggest that the difference in somatic embryo formation capacity observed between embryogenic cotyledons is related to their endogenous Z contents and that the endogenous hormonal balance between Z and IAA is an important index defining the embryogenic potential in peach cotyledons.
