Lingonberry and low-bush blueberry seeds lose their germination capacity quite quickly. The highest germination rate (70.4 per cent) was observed in lingonberry seeds of Variant 1(fresh strtified seeds) and the lowest (16 per cent) in those of Variant 4(2-year-old stratified seeds). Low-bush blueberry seeds showed the highest germination rate (84 per cent) in Variant 1(fresh stratified seed) and the lowest (26.8 per cent) in Variant 4 (1.5-year-old unstratified seeds). The rates in Variant 2 (unstratified same-year seeds) and Variant 3 (stratified 1.5-year-old seeds) did not differ significantly (44.8 per cent and 40 per cent respectively). Stratification led to a higher seed germination rate in both species. It appeared that both of the fertilisers used were fit for low-bush blueberry seedlings, and that their average effect on shoot height and seedling branching was approximately the same. Fertilisation with Expert Gardener sup(TM), however, resulted in a higher proportion of seedlings producing a large number of shoots than fertilisation with Peat PG-Mix. Fertilisation of seedlings twice during the first period of growth at a rate of 1g l sup(-1) proved sufficient. The shoots of plants fertilised three times did not lignify properly and were vulnerable to damage from low temperatures in winter
