Abstract:

Random amplified polymorphic DNA (RAPD) phenotypes generated by 15 primers were

scored in 5 subpopulatious of Anthoxanthum alpinum along an altitudinal gradient. Although few

subpopulation-specific markers were found, a significant population differentiation was revealed by

the use of principal factor analysis and Ward‘ s cluster analysis. The result was also confirmed by

the significant positive correlation when comparing beth the matrix of similarity between the individu-

als within subpopulations and the matrix among subpopulations, as well as the matrix of distances

and the differences of altitude between the subpopulations (Mantel test). This study suggests that

the differences of altitude between subpopulation sites may result in the differences of phenological

period for flowering and growth which restrict gene flow.
