Summary: | In Northern Finland as well as in Northern Sweden there is a shortage of high-quality Scots pine ( L.) seeds, mostly due to unsuitable temperatures during the development and maturation of cones and seeds. Methods have been developed for elimination of non-productive seeds and for invigoration of seeds. In the present work, these methods were tested on poorly developed seed lot from Rovaniemi, Northern Finland (66°15ââ66°30â; 180 m a.s.l.). The seeds were conditioned using the following treatments:Pinus sylvestris |
