OUTCROSSING RATES IN 2 STANDS OF NOBLE FIR (ABIES PROCERA REHD.) IN DENMARK

The outcrossing rates in 2 stands of noble fir (Abies procera REHD.) i n Denmark were determined from the segregation at 3 polymorphic allozy me loci in 20 progenies from 18 trees in each stand. The outcrossing r ates were found to be slightly smaller than one: 0.98 and 0.90, of whi ch only the latter value differed significantly from one. Noble fir th erefore resembles other coniferous species by reproducing according to a mixed mating system, although with low level of selfing. The differ entiation among the populations was relatively low, as commonly observ ed in wind-pollinated trees: the estimated F-ST, value was 0.029.
