Diversity and genetic structure of natural populations of the palm tree Euterpe precatoria (Arecaceae)

چکیده

Introduction: The natural ecosystems of northern Mato Grosso, Brazil, are in process fragmentation, mainly due to population growth and the expansion agriculture. This endangers palm Euterpe precatoria (locally known as açaí), used for construction, hearts, juices ice cream. Objective: To evaluate local diversity genetic structure native populations E. precatoria. Methods: We collected leaves from 106 fruiting palms five Grosso State, analysis microsatellite markers with Polymerase Chain Reaction. Results: SSR loci revealed a total 30 alleles, ranging 5 (EE23 EE43) 7 (EE2 EE15), an average 6 alleles per locus. mean PIC was 0.74 confirmed low heterozygosity inbreeding. UPGMA dendrogram produced two groups molecular variance greater differentiation within populations. high levels homozygous indicate diversity. Conclusions: These have gene diversity, number locus, rare exclusive alleles. recommend establishment permanent conservation units corridors among them.

Allometric Equations for Estimating Biomass of Euterpe precatoria, the Most Abundant Palm Species in the Amazon

Allometric models to estimate biomass components such as stem mass Ms, foliage mass Ml, root mass Mr and aboveground mass Ma, were developed for the palm species Euterpe precatoria Mart., which is the most abundant tree species in the Amazon. We harvested twenty palms including aboveand below-ground parts in an old growth Amazonian forest in Brazil. The diameter at breast height D ranged from 3...
