Uso, manejo y procesos de domesticación de pachycereus hollianus (f.a.c. Weber) buxb. (cactaceae), en el valle de tehuacán-cuicatlán, méxico

an ethnobotanical survey was conducted to document uses and traditional management of pachycereus hollianus in the valley of zapotitlán, within the tehuacán-cuicatlán valley in central-mexico. open and semistructured interviews showed that local people still use its products (stems, wood and fruits). six local variants with different kinds of edible fruit were identified and a clear association between plant and human populations was observed. the best phenotypes with large fruit and a red sweet pulp were found to be protected in managed areas and such management might have had effects on phenotype frequency in p. hollianus populations, increasing abundance through artificial selection principally directed towards sexual reproduction structures.
