Table 1.

Genetic diversity parameters based on ISSR for metapopulations of Zingiber corallinum and Z. nudicarpum. Subpop. size: number of adult plants per subpopulation; PL: number of polymorphic loci; PPL: percentage of polymorphic loci; N_a: number of observed alleles; N_e: number of effective alleles; h: Nei’s gene diversity; I: Shannon’s information index; NS: number of specific bands.
