Fig. 6From: Genetic variation and population structure of clonal Zingiber zerumbet at a fine geographic scale: a comparison with two closely related selfing and outcrossing Zingiber speciesCorrelogram showing the spatial autocorrelation coefficient (r) within four local populations of Zingiber zerumbet within the microgeographic area. (U and L represent the 95% two-tailed confidence interval, which was calculated based on 999 permutations; a-d–local populations DS1, DS2, MLH and HJC)Back to article page
