Comparison of genetic variability and growth characteristics of naturally regenerated and planted Scots pine

Compartment	Regeneration method	H (cm)	D (mm)	SQ	Density (thousand pcs/ha)	P (%)	N_a	N_e	I	H_e
168b	natural	10.9^a	3.4^a	32.1	39.0^a	70.73	1.512	1.384	0.339	0.225
196c	natural	12.2^a	3.6^a	33.9	41.0^a	87.80	1.854	1.498	0.441	0.293
Mean		11.5	3.5	33.0	40.0	79.26	1.683	1.441	0.390	0.259
246a	planted	32.1^b	9.3^b	34.5	9.2^b	71.95	1.524	1.423	0.372	0.248
256g	planted	33.9^b	9.9^b	34.2	9.5^b	71.95	1.610	1.410	0.360	0.239
Mean		33.0	9.6	34.3	9.3	71.95	1.567	1.416	0.366	0.243

H – height, D – diameter at the root collar, SQ – strength coefficient, P (%) – percentage of polymorphic loci, N_a – average number of alleles per locus, N_e – effective number of alleles per locus, I – Shannon index, H_e – expected heterozygosity;

a,b – homogenous group.

Result of principal coordinate analysis based on genetic distance of natural and artificial regeneration of Scots pine (168b, 196c – crops from natural regeneration; 246a, 256g – crops from planting)

Values of heterozygosity and gene flow index in natural and artificial regeneration of Scots pine

Regeneration	H_T	H_S	G_ST	N_m
Natural	0.3611±0.0208	0.2522±0.0177	0.3014	1.1589
Planted	0.3136±0.0290	0.2754±0.0233	0.1218	3.6051
Total	0.3652±0.0188	0.2636±0.0157	0.2783	1.2968

[i] H_T – total genetic diversity, H_S – intrapopulation differentiation, G_ST – interpopulation differentiation, N_m – gene flow.
