The article focuses on a study which reconstructs the rate of genetic recovery of the population of the hermaphroditic mangrove, Avicennia alba, in Mekong Delta 30 years after the use of Agent Orange, which is a mixture of phenoxyl herbicides. It evaluates the age of Avicennia alba with the use of models based on internode growth and genotypes samples for six microsatellite loci. It also compares the reconstructed evolution of genetic diversity since local extinction with the genetic diversity of an unaffected population from Thailand. Results show that genetic diversity of the population is increasing in Mekong Delta. However, the population is reaching an asymptotic level that is comparable to the Thai population.
