%X <p>The most common way to artificially regenerate cutting areas in Northern Finland has been sowing, which has, however, often given poor results. The aim of the study was to assess the success rate of sowing and study the causes of poor regeneration.</p>
<p>An inventory was made of 28 areas on <em>Empetrum-Myrtillus</em> and <em>Hylocomnium-Myrtillus</em> type sites sown with Scots pine (<em>Pinus sylvestris</em> L.) seeds in 1948-1950. In addition, to study the effect of substrata, a sowing experiment was established. According to the inventory, regeneration failed completely in 8 and partially in 6 of the 28 sown areas. Factors that explained the poor regeneration included unfavourable weather conditions in 1948-1952, insufficient clearing of sowing spot especially when the humus layer was thick, and insect damage by <em>Otiorynchus dubius</em> weevil.</p>
