The POD isozymograms of shelled seeds and embryos could be used to distinguish seeds of four species of Larix. The period of sampling isozymes was critical and the two periods B and C in radical lengths of germinating seeds were shown to be optimal for sampling. Based on the number of common zones, the degree of similarity of isozymograms and double axises system ordinations, the relationship of four species of the genus was also discussed.
