The emergence and growth of polymorphic and inbred progeny of pedunculata oaks seedlings derived from autumn and spring acorns seeding have been studied. It has been shown that the rate of emergence tends to be higher for the acorns collected from isolated trees. This confirms that the size of acorns has a beneficial influence on descendent viability. Seedling survival depended on the maternal tree genotype and was not influenced by the time of sowing. However, the seedlings produced after spring sowing showed a higher growth rate compared to those produced after autumn sowing. The difference in the growth rate was observed visually beginning from the age of three years. Taking into account that oak seedling growth is slow during the first two years, it is recommended to remove weeds in plantations during the first three years (for spring seeded plantation) and four years (for autumn seeded plantation).
