Abstract

lsozyme variation in sambong collected from Los BaAos, Laguna and Mandaue City, Cebu was studied using starch gel electrophoresis. Three enzyme systems were used namely: esterase, acid phosphatase and alkaline Phosphatase. Two distinct esterase hands, EST F and EST S at RI range, of 0.417 to 0.429 and 0.375 to (1.388, respectively were visualized. These bands produced two phenotypes designated as EST FS and EST SS. The population from Los Banos was found monomorphic with a single phenotype, EST FS, observed while plants from Mandaue was polymorphic with two phenotypes, EST FS and EST SS was observed. The total Population did not significantly show a goodness-of-fit of the observed with the expected frequencies under Hardy-Weinberg equilibrium possibly due to the common practice of propagating the plants by stem cuttings. Acid and alkaline phosphatases were found monomorphic in both populations.
