This study deals with the climatic adaptation of Scotch pine (Pinus sylvestris L.) in eight
locations in whole Finland. The principal aim was to show the survival of the seeds, their viability to
produce a tree, in different climatic conditions across four studied years, and in last term, the tree
survival and wood tree production.
The present investigation used information from seed weight and amount, flowering days
and climatic conditions. The objectives were to quantify the number of viable seeds (figure 2) per
cone and its weight. On the other hand, the role of the sum of the daily temperature, above 0 º C,
and its relation to seed’s weight and production. Also, it was relevant to measure the importance of
the flowering day and how it affects seeds' development. All together, the purpose was to find what
is going on, nowadays, in Finland regarding seed reproduction and survival and its relation with the
new climatic conditions.
This work is presented as a Bachelor Thesis of Forestry Degree in the Polytechnic
University of Valencia (Spain). The whole study was carried out at both the Finnish Forest Research
Institute (METLA) and the University of Helsinki as a result of the signed agreements between those
within the European Erasmus exchange student program.
