Badania nad zmiennością genetyczną w naturalnie odnawiających się populacjach daglezji zielonej (Pseudotsuga menziesii (Mirb.) Franco)

Genetic variability of Douglas fir was studied in seven naturally regenerated populations. The genetic structure of the self−sown young generation was described by means of variability of eight enzymes (Dia, G−6−pd, Got, Idh, Pgi, Pgm, Sdh and Shdh) separated electrophoretically on a starch gel. The results indicate that no substantial reduction of the genetic pool and no substantial inbreeding effect were observed in naturally regenerated Polish populations of this introduced species.
