Abstract: An experiment was conducted to study the differences in fat soluble constituents in six poplar clones with different anti-rust resistances by ultrasonic extraction technique with petroleum ether and GC-MS analysis in order to shorten the breeding time.The six poplar clones were I108,03-04-170,03-04-141,03-04-111,N177 and N195.Results show that the diffe-rences in fat soluble constituents are significant in the buds of poplar with different anti-rust resistances.The buds of N195 and N177 which resist poplar rust well contain such endemic elements as α-Caryophyllene,alpha-Bisabolol,and methyl arachidate.Cinnamic acid,4-Cyanophenyl-propylbenzoate,9-Phenanthrol,Chlorodiphenylmethane,retinaldehyde,and p-Hydroxy-cinnamic acid only exist in N195,while α-cadinol,2-Phenethyl octanoate,9-Aminoacridine,and 1-Docosanol only exist in N177.Therefore,the differences in fat soluble constituents in poplar buds may determine the rust resistance in poplar.
