Table 2. Parameters of habitat quality and sexual reproduction in the B. nana populations. Pop = populations codes according to Table 1; Hab = number of habitat plots; Habitat quality parameters: EC = electrical conductivity; Reproductive parameters: GS = number of germinated (without scarification) seeds per individual, GSC = number of seeds germinated after scarification, ES = number of empty seeds (without ovule), PF = number of partly filled seeds, IN = number of seeds infected by insects; # = median values. | ||||||||||||||||||
