Abstract

To biochemically characterize the 25 accessions of pili, Canarium ovatum Engler. an indigenous nut in the Philippines collected from Oas, Albay, starch gel electrophoresis was performed. The four enzymes studied were Glucose-6-Phosphate Dehydrogenase (G6PD), Glutamate-oxaloacetate Transaminase (GOT). Esterase (EST). and Phosphogluconatc Dehydrogenase (PGD). A total of 8 presumptive loci were observed. All eight loci were polymorphic. For the eight presumptive loci. three loci were noted for the enzyme G6PD: G6PD-1, G6PD-2. and G6PD-3. Two presumptive loci for the enzyme EST were noted: EST-1 and EST-2. and two presumptive loci for the enzyme PGD: PGD-1 and PGD-2. GOT had a single locus designated as GOT-1. The total population differentiation Sr of the gene pool for this population was found to be equal to 0.59. This value could be due to the fact that though all the accessions were from Oas. Albay, the dioecious nature of pill contributed to the variability found in this population. Also, the trees may have been established in the field of IPB through asexual method of reproduction.
