摘      要：The Brazilian state of Acre has an extensive natural reserve of bamboo,making it one of the largest in loco gene *** aim of this study was to characterize the structure and genetic diversity of Guadua weberbaueri *** two populations,one native(FAPB)and the other anthropized(FAPBA),using ISSR *** results show that the FAPB population exhibited higher values for all estimates of population ***,the FAPBA population also showed high heterozygosity,corroborated by estimated gene flow(Nm=3.9)between the *** study of the association between Nei’s genetic distances and the geographic distances between the populations were significantly correlated(r=0.45,p=0.01),corroborated by the dendrogram revealing two distinct groups corresponding to the collection sites,without mixing classes between populations in the same *** for the coancestry coefficient,pairs of individuals in the first distance class were positive and significant,indicating that plants that are geographically closer share common alleles with a frequency greater than by chance,which means that there is a tendency that geographically closer individuals are *** presented similar genetic structure when the geographical distance between them was up to 56 m for FAPB and up to 156 m for *** was concluded that anthropized environments exhibit less genetic diversity than native environments,inferring risks for species conservation if appropriate and planned management techniques are not adopted.
