Evaluación poblacional y mediciones dasométricas de torote prieto Bursera laxiflora S. Watson en condiciones silvestres

The wild populations of endemic plants present in the ecosystems of northwestern Mexico show variability between populations of the same species. The black torote (Bursera laxiflora) is a plant with medicinal uses. The objective of this work was to evaluate the existence of black bull specimens as well as dasometric measurements in two wild sites. The results obtained according to the population of black torote in each site, for S1, there were 74 plants ha^-1 while in S2 there were 58 plants ha^-1, showing an increase of 21.32% in S1, these populations show that in S1 there is one specimen in every 135.13 m² and in S2 a plant is located in every 172.41 m². The evaluated dasometric measurements did not show significant differences (P> 0.05), in relation to height, in S1 an average of 2.52 meters was presented, in S2 the plants presented 2.25 meters. The average aerial coverage for S1 was 4.54 m², while for S2 the average was 3.64 m². Regarding the average basal coverage, the plants evaluated for S1 showed 283.45 cm² and S2 was 190.24 cm². The results obtained in this evaluation show that the plants have the same behavior in their height, aerial and basal coverage, therefore the plants are similar in their phenotypic structure in both sites.
