摘要：
Oil Palm pollen extracts of 97 palms from 31 open pollinated progenies froin Bahia State, Brazil, were analyzed for fluorogenic esterases through polyacrylamide gel isoelectric focusing at two pH gradients. There were a large number of bands distributed over five activity regions. Regions A, B and C presented monomorphic patterns and isozymes of region D were difficult to analyze. The observed profile for region E (esterases E1 and E2) suggests that this control of this esterase is determined by two alleles and that this enzyme has a monomeric structure. Allelic and genotypic frequencies are presented for this locus. A hypothesis for genetic control of the two isozyme variants detected is presented.
